1 General
This guideline describes the process of the certification of welding manufacturers for the welding of railway vehicles and components according to EN 15085-2 "Railway
applications – Welding of railway vehicles and components – Part 2: Quality
requirements and certification of welding manufacturer" and serves to define a uniform procedure. It is binding for all manufacturer certification bodies participating in this certification system and also includes supplementary information on the standard. The Federal Railway Authority (EBA) is the national safety authority responsible for railway traffic in Germany. The rules and regulations issued by the EBA must be taken into account for the certification of the welding manufacturers.
Note: For railway traffic on non-federal railways, rules and regulations of the relevant
authorities of the federal states may have to be observed.
The Railway Vehicles Coordination Committee is the responsible steering body to ensure a uniform procedure of the manufacturer certification bodies.
This guideline was prepared by the Coordination Committee in collaboration with DVS Working Group A7, "Welding in the Construction of Railway Vehicles".
The certification of welding manufacturers is based on generally accepted rules of technology. For the welding of railway vehicles and components, these generally accepted rules of technology are embodied in:
− the EN 15085-1 to EN 15085-5 series of standards, and − additionally applicable reference standards.
Welding manufacturers wanting to undertake welding work in new build (including finishing welding) or in repair must provide evidence of their qualification according to EN 15085-2.
Welded subassemblies of railway vehicles and components that have been
manufactured or repaired by welding manufacturers not in possession of the required certificate are not considered to comply with the standards.
Manufacturers who do not perform any welding work themselves but - design, or
- purchase & assemble, or - purchase & resell
welded components and subassemblies require a certificate for the certification level CL 4.
Such qualification is considered to have been demonstrated if a certificate has been issued by a manufacturer certification body. A welding manufacturer having several welding facilities requires a separate certificate for each facility.
The certificate becomes invalid when the prerequisites upon which it was granted, no longer exist.
Annexes 6 and 8 contain supplementary regulations on the repair of railway vehicles and/or for the transition from the DIN 6700 series of standards to the EN 15085 that are only applicable to railway traffic in Germany.

3 Classification of the certificates
The certificates are classified based on the certification levels (CL) defined in EN 15085-2.
According to EN 15085-2, section 4, these certification levels depend on the weld performance class (CP) of the welded joints and the safety relevance of the
components and subassemblies. The certification levels should be specified in the relevant drawing (see EN 15085-3). In the absence of such specification, the
certification level according to EN 15085-2 must be determined prior to submitting the application. For this purpose, the national safety authority (which in Germany is the EBA) and the customer should be consulted as appropriate.
The certification levels that are included in the level for which the certificate was issued are listed in the following Table 1:
Table 1. Included certification levels
Certified Included certification level
certification level CL 1 CL 2 CL 3 CL 4 CL 1 X
1) CL 2 X
2) CL 3 X CL 4 X 3)X Certified certification level.
Included certification level.1) A CL 1 certificate also permits design or purchase & resale or purchase & assembly for all certification levels if so indicated in the certificate.
2) A CL 2 certificates also permits design or purchase & resale or purchase &
assembly for the certification levels CL 2 and CL 3 if so indicated in the certificate. 3) A CL 4 certificate permits design or purchase & resale or purchase & assembly
for the certification level specified in the field of application of the certificate. Note: If CL 4 for design is not included, this must be indicated in the certificate.
4 Requirements
The requirements on the welding manufacturer for the certification level applied for can be seen from EN 15085-2. For details please refer to section 5 and Annex C of EN 15085-2. Further explanations are included in Sections 4.1 to 4.4 of this Guideline.
4.1 Quality requirements
With regard to the EN 15085 series of standards, the welding manufacturer must demonstrate its compliance with the requirements of EN ISO 3834-2 to EN ISO 3834-4 to the manufacturer certification body. For details, please refer to Annex C of EN 15085-2.
Evidence of calibration and validation of the measuring, inspection and testing
equipment (see section 16 of EN ISO 3834-2) is only necessary if this is contractually required.
4.2 Staff requirements 4.2.1 Welding coordinators
The welding manufacturer must demonstrate its compliance with the requirements of section 5.1.2 and Annex C of EN 15085-2. EN 15085-2 contains minimum
requirements on the availability of welding coordinators. The required number of welding coordinators depends on the size of the welding manufacturer as well as the extent of the welding production and the number of subcontractors.
The tasks and areas of competence of the welding coordinators must comply with the requirements of EN 15085-2, Annex B. They must be laid down in writing for each welding coordinator and must be verified by the manufacturer certification body as part of the audit for the certification. The independence of the welding coordinators must be clearly shown in an organization chart. The manufacturer certification body must verify that the responsible welding coordinators are integrated in the organization of the welding manufacturer in a way that allows them to attend to their tasks in their areas of competence pursuant to EN ISO 14731 without any restrictions. For this purpose, they must have the required authority to instruct and their own decision-making power. If the areas of competence are separated (e.g. for production, subcontracting and design), this must be indicated in the certificate.
The welding manufacturer must provide evidence of the professional experience of its welding coordinators (e.g. evidence of qualification).
Welding coordinators without a qualification according to the relevant IIW/EWF
guidelines (IWE/EWE, IWT/EWT, IWS/EWS) must demonstrate the necessary technical knowledge on welding during an extended interview as part of the certification audit. In addition, the welding manufacturer must furnish evidence of the professional experience of the welding coordinators.
Note: For further details, please refer to section 5.3.2 "Interview with welding coordinators" of this Guideline.
Section 5.1.2 of EN 15085-2 specifies who may deputise without restriction for the responsible welding coordinator.
4.2.2 Subcontracted welding coordinators
Welding coordinators who are not employed directly (on site) by the respective welding manufacturer are "subcontracted welding coordinators" (referred to below as "external welding coordinators) – please refer to section 5.1.3 "Subcontracted welding
coordinator" of EN 15085-2. This also applies to part-time staff who work less than 50% of the collectively agreed working hours.
According to EN 15085-2, the responsible welding coordinator may be subcontracted in special cases.
For subcontracted welding coordinators, the following must be observed:
The working hours of external welding coordinators must be contractually agreed so that they can perform their tasks as defined in Annex B of EN 15085-2 (evidenced in a work book).
In addition, the following applies:
For new build production, the external welding coordinator should be present
during at least 50% of the welding production within scope of the relevant standard (evidenced in a work book),
For repair/finishing welding, the required presence depends on the extent of the
welding production within the scope of the relevant standard (evidenced in a work book).
Auditors of a manufacturer certification body may not act as external welding coordinators.
A welding coordinator may only be approved for a maximum of two welding manufacturers. For certification level CL 4 (manufacturers without own welding production), a welding coordinator may serve a maximum of three manufacturers. The following table shall apply
Maximum number of manufacturers for which a welding coordinator may be approved:
Variant CL 1, CL 2 CL 4
A 2 1 B 1 2 C - 3
In that case, all work books must be submitted to the auditor of the manufacturer certification body to allow an assessment of the overall extent of his or her work.
4.2.3 Welders/welding operators
For each welding process, material group, joint type and dimension, at least two
welders/welding operators with a valid qualification pursuant to the applicable standards must be available.
Since both butt and fillet welds are common in railway vehicle construction, the welding manufacturer must furnish BW and FW welder qualification test certificates.
The field of work of welders/welding operators in production must be in line with the scope of the available qualification test certificates.
For welding work that is not covered by the welder qualification test, the welding manufacturer must additionally provide evidence of production weld tests prior to production as required by section 4.2.4 of EN 15085-4. Their performance and validity are governed by DVS 1621.
Weld operators must be qualified pursuant to EN 1418.
4.2.4 Inspection personnel
According to section 5.1.4 of EN 15085-2, the welding manufacturer must have inspection personnel.
The existence of certified inspection personnel pursuant to EN 473 must be
demonstrated if inspections in the inspection classes CT 1 and CT 2 according to EN 15085-3 are required.
4.3 Equipment
The production workplaces, including workplaces for assembly, must be sufficient in size and nature to allow a proper and reproducible performance of welding work. The requirements of section 5.2 of EN 15085-2 must be complied with.
4.4 Welding procedure specifications
According to EN 15085-2, welding procedure specifications (WPS) in line with EN ISO 15607 (EN ISO 15609ff, EN ISO 14555, EN ISO 15620) are required for welds of the weld performance classes CP A to CP C3. Evidence must be furnished as described in section 4.1.4 of EN 15085-4.
Existing approved welding procedure specifications remain valid.
The evidence based on available experience (EN ISO 15611) only applies to welds of the weld performance class CP C3 (see EN 15085-4)
4.5 Organization of welder qualification tests, acceptance of production weld tests, approval of welding procedure specifications
The welding coordinators recognized for the welding manufacturer are authorized to organize, evaluate and conduct welder qualification tests, accept production weld tests, and conduct inspections for the approval of welding procedure specifications.
Conditions:
○ The welding coordinators must have demonstrated appropriate technical knowledge and skills in the audit.
○ The welding coordinators concerned with these responsibilities must be named in the certificate pursuant to EN 15085-2.
4.6 Supplementary regulations
4.6.1 Manufacturer's qualification for longitudinally welded pipes as semi-finished products
For the manufacturing of longitudinally welded pipes (with the welding procedures HF, LB) that are to be used as semi-finished products for the certification levels CL 1 and CL 2, a manufacturer's qualification is required.
Instead of a certification pursuant to EN 15085-2, also one of the following comparable certifications may be accepted:
○ Certification pursuant to EN ISO 3834-2 including qualification of the welding procedure pursuant to EN ISO 15614
○ Certification pursuant to the Building Products Guideline, system 2+ ○ Certification pursuant to AD 2000 code W 0.
4.6.2 Single-purpose production
Single-purpose production in the certification level CL 1 is the fully mechanized welding production of identical subassemblies in a series (e.g. cardan shafts).
The certificate pursuant to EN 15085-2 must be limited to the subassembly and the welding procedure specification.
Notwithstanding the requirements of EN 15085-2, a responsible welding coordinator of the qualification level B may be approved for this purpose.
Details on the inspection and verification measures must be agreed with the
manufacturer certification body, a shorter verification interval (e.g. every six months) may be agreed.
4.6.3 Finishing welding
Finishing welding on subassemblies of the certification level CL 1, the manufacturer (foundry) must furnish proof of the warranted properties and the necessary casting quality by tests and inspections. The evaluation criteria (such as weld performance class) and the inspection procedures (such as weld inspection class) must be
determined by the welding coordinator and – if contractually agreed – be aligned with the customer.
The responsible welding coordinator may also be a foundry engineer if he/she has demonstrated "comprehensive technical knowledge" pursuant to EN ISO 14731 for this field of application in the interview.
The manual skill of the welder may be demonstrated by an appropriately documented production weld test.
4.6.4 Friction stir welding – application of the welding process
For the application of friction stir welding, the following provisions apply: o Process number: 43 according to EN ISO 4063, draft 2008-03
o Materials: aluminium and Al alloys
o Dimensions: all dimensions for which evidence of welding procedure specifications pursuant to EN 15085-4, section 4.1.4 is available at the welding manufacturer.
o Quality requirements: weld performance classes CP A to CP C2 according to EN 15085-3.
o Scope of inspection: corresponding to EN 15085-5, table 1. o Operational prerequisites:
- Certified according to EN 15085-2: certification level CL 1.
- Welding coordinator: Level A according to EN 15085-2; for manufacturers only certified for friction stir welding, a responsible welding coordinator of the qualification level B may be approved.
- Welding operator qualification test: according to EN 1418.
- Welding procedure specification: according to EN ISO 15609-1, evidence according to EN ISO 15614-2.
- Production weld tests: according to EN ISO 15613 with the following scope of verification:
visual inspection according to EN 970 radiography according to EN 1435
technological bend test according to EN 910 macrosection.
4.6.5 Weld performance class CP – Permissible shapes of welds – Allocation of the weld inspection class CT
As a matter of principle, the selection criteria according to EN 15085-3, tables 2 and 3 apply.
In addition, the following specifications must be observed:
a) Permissible shapes of welds:
CP Permissible shapes of welds
CP A Applies only to welds with full penetration and full accessibility for inspection (NDT) in production and maintenance.
CP B 1. For safety category "high":
Applies only to welds with full penetration and full accessibility for inspection (NDT) in production and maintenance.
2. For safety category "medium":
Also applies to welds without full penetration and without the possibility of a volumetric test. Testing for surface cracks in production and maintenance must be possible.
CP C1 Also applies to welds without full penetration and without the possibility of a volumetric test. Testing for surface cracks in production and maintenance must be possible.
CP C2, CP C3, CP D
Applies to all shapes of welds without special requirements on the testing of the welds; visual inspection in production is sufficient. For maintenance, generally weld performance class CP C 2 applies, if appropriate with higher weld inspection class CT.
b) Allocation of the weld inspection class CT:
Considering the material conditions (e.g. materials tending to crack), a different allocation may be decided; e.g. for steels of group 11 according to CEN ISO/TR 15608: CP C2 - CT 2 (100% VT + 10% surface tests).
5 Certification procedure and verification
Section 6 of EN 15085-2 describes the procedure for certifying welding manufacturers. The manufacturer certification body must audit and verify the welding manufacturers in a way that it can be demonstrated that the requirements of the EN 15085 series of standards and this Guideline are complied with.
For subcontracting, the DVS 1617 code of practice includes further information.
5.1 Manufacturer certification bodies
Audits may only be performed by the manufacturer certification bodies recognized by the national safety authority. In Germany, the EBA keeps a list of the recognized manufacturer certification bodies. The manufacturer certification bodies must be included in the Online Register Railway Vehicles (register of the certified welding manufacturers in railway vehicle construction) (see section 5.6).
5.2 Application
Annex 1 contains the "Application for certification for the welding of railway vehicles and components according to EN 15085-2". The application for the initial or renewed
certification must be addressed by the welding manufacturer to one of the manufacturer certification bodies recognized by the national safety authority. With the application, the welding manufacturer confirms that it complies with the generally accepted rules of technology and that it submits to the annual verification.
The manufacturer certification body issuing the certificate must be notified of any modifications occurring during the period of its validity.
If it can be seen from the application that the manufacturer used to be handled by another manufacturer certification body, the "new" manufacturer certification body must inform the "old" manufacturer certification body. The documents on the previous
certification(s) must be made available to the "new" manufacturer certification body. After the completion of the certification procedure, it must be verified that the welding manufacturer is only listed once in the Online Register Railway Vehicles.
If an external welding coordinator has been recognized by several manufacturer certification bodies, these must consult with each other.
For a renewal of the certificate, the application form must again be completed and the "renewal application" box must be checked. If no changes have occurred in the meantime, the submission of the Annex(es) to the application is waived.
With its application for certification according to EN 15085-2, the welding manufacturer defines the range of certification (welding process, material group according to CEN ISO/TR 15608, dimensions) in a way that it meets the requirements for its welding production.
In the certification procedure, the welding manufacturer must furnish evidence that it has the welder qualifications tests and evidence of welding procedure specifications required for the range of certification applied for; if applicable these must be
supplemented by production weld tests (this applies in particular to repair welding manufacturers).
5.3 Audit
The certification is preceded by an audit.
During that audit, the welding manufacturer must demonstrate that the welding
coordinators have the technical knowledge on welding and the qualification as required by section 5.1.2 of EN 15085-2 (see also further information on the interview in sections 4.2.1 and 5.3.2 of this guideline).
The extent of the audit depends on the certification level, the field of application, the number of welders and the welding procedures, the scope of the welding shops and the materials used. As part of the audit, the following is verified:
− available personnel including evidence of valid qualification test certificates − equipment including production and production quality
− welding procedure specifications, qualification of welding procedures
− documentation of the welding planning (drawings, welding plan, inspection and test
plan).
− compliance with the quality requirements of EN ISO 3834-2, -3 and/or -4.
As part of the first audit, welding tests in the form of production weld tests, welder qualification tests or procedure qualification tests are mandatory to demonstrate the practical knowledge of the welding coordinators. Otherwise, welding tests are required for planned new entries of welding coordinators, procedures and material groups as required by the applicable standards.
Note: Welder qualification tests and/or production weld tests may only be accepted by
welding coordinators who have demonstrated the related qualification as part of the audit. The test certificate may only be issued by welding coordinators who are identified in the certificate of the welding manufacturer.
If the manufacturer has welders with valid qualification tests certificates, the verification is performed on the basis of production weld tests for the responsible welding
coordinators' evaluation.
If the required welder/welding operator qualification test certificates are not available, these tests can be made as part of the audit and the related certificates can be issued by the manufacturer certification body.
For a renewal of the certificate, some of the welder qualification tests or production weld tests accepted by the welding coordinators must be submitted to the manufacturer certification body for examination.
If the manufacturer certification body does not confirm the test results, new tests have to be taken. If there are doubts concerning the knowledge and skills of the welders, production weld tests will be necessary, so test specimens with tack welds should be available.
The test covers: welding procedure specification, evaluation sheet, issued test certificate, memorandum on the verification of the technical knowledge and the weld test specimens.
The welding coordinators must keep a list of the employed welders showing which welders have which valid qualifications. The welding coordinators are also responsible for making the relevant entries on the semi-annual internal qualification renewals at the manufacturer's (may be software-assisted).
For certification level CL 4, the compliance with the requirements of sections 5.1 (welding coordination) and 5.3 (welding coordination organization) of EN 15085-2, and the compliance with the quality requirements of EN ISO 3834-3 (if applicable) must be verified.
5.3.1 Site inspection
Site inspections are made together with the welding coordinators. During these
inspections, the implementation of the above requirements in the welding production is verified.
In addition, the proper execution of the welded subassemblies and structures resulting from the current production will be verified.
If during the initial certification, no corresponding subassemblies are in use, the first verification audit is made when production is started.
5.3.2 Interview with welding coordinators
During this informal interview, documents (such as technical books, training documents, standards, guidelines) or provisions if any issued by the national safety authority may be used freely.
In the interview, the welding coordinators must demonstrate technical knowledge on the special requirements of the EN 15085 series of standards and the related DVS codes of practice / guidelines. This also includes any other standards and regulations applicable to the field of activity. This does not mean that the welding coordinators must know all these standards and regulations by heart. Rather, they must know where to find provisions on specific problems. To demonstrate this, the welding coordinators must find the applicable standard and the relevant provision included in it within a reasonable time. The standards must be available in a language that the welding coordinators understand.
The questions are limited to issues that may arise within the scope of the standards, materials and welding procedures for which the certificate is applied for.
Persons without a IIW/EWF qualification who are to be recognized as welding
coordinators must demonstrate the required technical knowledge pursuant to EN ISO 14731 and section 5.1.2 of EN 15085-2 in an extended interview.
As a matter of principle, the technical knowledge according to section 6 of EN ISO 14731 must be demonstrated depending on the level of the welding coordinator. In addition, adequate knowledge must be demonstrated in the fields listed below,
depending on the certification level. In this respect, the national rules and regulations on occupational safety and the prevention of accidents must be taken into account.

The manufacturer certification body documents its professional/technical assessment in a report based on the sample enclosed as Annex 2 to this Guideline. An official copy of this report is given to the welding manufacturer and a copy is sent to the national safety authority.
5.5 Final discussion
The result of the audit is evaluated in a discussion with the welding coordinators and, if appropriate, with the management of the firm.
5.6 Issuance of the certificate
Upon a successful audit, the manufacturer certification body issues a certificate
pursuant to Annex 3 (for CL 1 to CL 3) or Annex 4 (CL 4) of this Guideline which states that the welding manufacturer is qualified to perform welding work in line with the requirements of the standard and the manufacturer certification body posts the certificate in the Online Register Railway Vehicles (link: "www.en15085.net" or "www.en15085.de") The manufacturer certification body is obliged to post the
certificate in the Online Register Railway Vehicles within two weeks of completion of the certification procedure.
Only certificate posted in the Online Register Railway Vehicles are valid.
The certificate is posted in the Online Register Railway Vehicles in one of the three language versions of the EN 15085 series of standards agreed within Europe (German, English, French). The welding manufacturer can specify the language in its application. The qualification of the welding coordinators must be stated in line with EN 15085-2. For comparable foreign qualifications, the manufacturer certification body must evaluate their equivalence. The certification level according to EN 15085-2 must be stated in the certificate.
As a minimum, the certificate must contain the following information:
− Name and address of the welding manufacturer
For each welding manufacturer, a separate certificate is required.
− Certification level
Here, the highest certification level pursuant to EN 15085-2 must be stated.
− Field of application
The field of application must be stated in line with Annex A of EN 15085-2. If there are any restrictions, these must already be indicated in the field of application. It must also be indicated if the "design" field of application of certification level CL 4 is not to be included in the range of certification of certificates of levels CL 1 or CL 2 (recommended wording "except design").
Finishing welding recognition for a single-purpose production must be stated separately.
For CL 4 certificates, also the allocation of parts and subassembly allocation with the corresponding certification level must be stated for the range of certification.
− Range of certification
the welding manufacturer's responsibility to ensure that the welder qualification tests and the evidence of welding procedure specifications required for the respective job are available.
○ Welding processes
Welding processes must be indicated using the nomenclature and reference number of DIN EN ISO 4063.
○ Material groups
The following specifications apply to the definition of the materials:
- Indication of the materials according to the CEN ISO/TR 15608 technical report; for steels of groups 1 to 3, the sub-group must be indicated, for all other materials, the group is sufficient.
- Materials that cannot be allocated to a group according to CEN ISO/TR 15608 (e.g. materials pursuant to CIS standards) are identified in the comments section. Austenitic manganese steel is indicated as "Austenitic manganese steel" in the materials section. This material is included in the Online Register Railway Vehicles.
Based on the EN ISO 15614 ff. series of standards, Annex 5 contains the also applicable material groups and related material designations of the materials customary in railway vehicle construction.
○ Dimensions
The following specifications apply to the definition of the dimensions:
- The dimensions must be clear and be stated separately for sheets and pipes. The dimensions to be stated include the wall thickness tmin - tmax and for pipes
additionally Dmin - Dmax.
- In special cases, there may be deviations for fillet welds (e.g. hard facing with austenitic manganese steel plates, grounding bushes)
- Fillet weld thicknesses are only in exceptional cases included in the dimensions (e.g. in case of single-purpose production)
- Ranges of dimensions are not to be stated with decimal points but rounded. ○ Comments
Special characteristics, e.g. type of weld, overlay welding, finishing welding, must be stated in the range of certification or on the reverse. If they are stated on the reverse, this must be indicated on the front.
− Responsible welding coordinator
First name, family name, date of birth, IIW/EWF qualification (e.g. IWE/EWE,
IWS/EWS, IWT/EWT, IWP/EWP) or level according to EN 15085-2 must be stated. In case of separate areas of competence, these must be indicated as well (e.g. design, production, different organizational units). External welding coordinators must be marked "external".
− Deputy with equal rights
First name, family name, date of birth, IIW/EWF qualification (e.g. IWE/EWE, IWS/EWS, IWT/EWT, IWP/EWP) or level according to EN 15085-2 must be stated.
− Additional deputies
First name, family name, date of birth, IIW/EWF qualification (e.g. IWE/EWE,
IWS/EWS, IWT/EWT, IWP/EWP) or level according to EN 15085-2 must be stated. Note: If additional deputies are stated on the reverse, this must be indicated on the front.
− Certificate number
The nomenclature described in Annex 5 of this Guideline must be observed. The year of the initial certification is kept. Each welding manufacturer may only have one number (no duplication of numbers).
− Period of validity − Date of issue − Name of auditor − Signature
(head of the manufacturer certification body or its authorized representative)
5.7 Period of validity of the certificate
The certificate is issued for a limited period and subject to revocation. It is valid for a maximum period of three (3) years. If there are good reasons, the manufacturer certification body may make the validity of the certificate contingent on the satisfaction of additional conditions (e.g. additional welding coordinators, testing and assignment of additional welders, additional inspection and testing as part of the quality assurance, continuous production weld tests, production verified by the manufacturer certification body); any such conditions must be stated in the report according to Annex 2.
5.8 Verification
As stipulated in section 7 of EN 15085-2, the manufacturer certification body verifies the compliance with the requirements of EN 15085-1 to -5 in the field of application for which the certificate was granted during the period of the certificate's validity. The verification relates to the current production (parts, subassemblies) and the quality records on running and completed projects as well as to knowledge about new standards and regulations.
The verification is based on the following principles:
− compliance with EN 15085-1 to -5; and
− annual verification on site by the manufacturer certification body.
The annual verification will also be carried out if no parts or subassemblies according to EN 15085 ff are available in the workshop at the time of the audit. This means that the welding manufacturer must in any case demonstrate that it continues to satisfy the staff-related and operational requirements of the standard for as long as its certificate is listed in the register. This serves to ensure that follow-up jobs can be processed without delay.
If certification was granted with conditions, the verification interval may be shortened, depending on the extent of production.
(e.g. in case of separate welding shops).
5.9 Renewal of the certificate
After the period of validity of the certificate has expired, the certificate may be renewed following an audit of the welding manufacturer (site inspection) by the manufacturer certification body without comprehensive interview and production weld tests if: the welding coordinators continue to perform their functions without any changes
over the previous certification and
the technical, staff-related and organizational conditions comply with the requirements of the standard and
valid qualification test certificates for the welders and the welding personnel are available and
there have been no material complaints in the range of certification.
During the site inspection, the welding coordinators must also demonstrate their knowledge of new standards and regulations.
5.10 Modification of the certificate
If there are any changes in the scope of the certificate, a modification application (no special form required) must be submitted to the manufacturer certification body without delay.
5.11 Revocation of the certificate
The manufacturer certification body or the national safety authority may revoke a
certificate if the conditions pursuant to EN 15085-2 are no longer satisfied. The welding manufacturer must acknowledge the revocation to the manufacturer certification body in writing. The national safety authority must be notified of the revocation by the
manufacturer certification body. The main customer for the current production must be informed of the revocation by the welding manufacturer.
5.12 Validity of the certificate
The certificate is only valid for the respective welding manufacturer (site of the facility) and its welding coordinators.
5.13 Exceptions
Any exceptions and disputes between the welding manufacturer and the manufacturer certification body are decided by the national safety authority.
In case of violations against generally accepted rules of technology or this Guideline, the national safety authority must be informed (e.g. also by the customer).
