Scheme rules for thermal insulation products for building equipment and industrial installations - VDI certification scheme

April 6, 2011

1. Introduction

This document presents the rules of the VDI product certification scheme "VDI-Mark" for thermal insulation products for building equipment and industrial installations, based on harmonised European product standards.

NOTE 1 The attestation of conformity procedures for this quality mark provide product certification related to all the requirements of the standard and to all characteristics (properties) of the product as declared by the manufacturer, complementing the requirements for CE marking. Product audit testing is included.

These scheme rules are largely based on the existing Keymark scheme for factory made thermal insulation products for buildings and on the VDI scheme for thermal insulation products intended for industrial installations.

NOTE 2 The Keymark scheme for building insulation products was established in 2001 for products according to the product standards EN 13162 through EN 13171. See the web site for further information www.key-mark.org

NOTE 3 The VDI-Mark has been applied for more than two decades and requires a high quality level for insulation materials for industrial installations in the European market. The quality assurance scheme was established by VDI Verein Deutscher Ingenieure e.V. for thermal insulation products for industrial applications based upon the Guideline VDI 2055. The scheme rules are maintained by the VDI-AG "Quality Assurance" ("Gütesicherung") working group. The VDI-AG "Quality Assurance" uses an acknowledged certification body on the basis of a contract for the execution of its resolutions and for organisational support.

The VDI-mark does not apply to insulation products used in heating and exhaust equipments in account of national regulations like EnEV (Energy saving regulation) in Germany.

In case of certification of products where no European Standard exists, the rules given in appendix H apply.

Insulation products carrying the VDI-Mark must have a significantly positive energy balance: This means the reductions in energy used and emissions produced during the service life of an VDI-certified insulation product by far exceed the energy required for and the emissions generated during its production and later disposal.

To limit costs and time delay for manufacturers, the product certification scheme is based on the following principles:

- Scope: Common technical specifications

- Organisation of the body responsible for managing the scheme – Quality Assurance Committee, see appendix G

- Acceptance of conformity assessment bodies (inspection, testing and certification) - Application procedures

- Conformity assessment procedures (inspection, testing and certification) - Fee-system

- Website

- Rules for handling complaints, disputes and appeals - Right to affix markings

The scheme rules will adopt all decisions with regard to conformity assessment with the technical specifications (see 2), taken by Sector Group 19 “Thermal insulation” of the Group of Notified Bodies under the CPD.

8.3 Attestation system 8.3.1 General

The attestation scheme is based on Product certification system 5 in accordance with ISO/IEC Guide 67 and consists of:

- Tasks for the manufacturer:

- Implementation and maintenance of a factory production control system

- Testing of samples taken at the factory by the manufacturer in accordance with a prescribed test plan.

- Tasks under responsibility of the certification body:

- Sample taking of products, representative for the product to be placed on the market - Initial type testing (ITT)

- Initial inspection of factory and of FPC

- Continuous surveillance, assessment and approval of factory production control - Audit-testing of samples taken at the factory

These tasks are performed in accordance with the relevant product specification (see 2) and EN 13172 and EN ISO 13787. Additional requirements are specified in annexes to the scheme rules.

When all requirements have been met by the manufacturer, the Certification body issues a certificate of conformity of the product.

Note: Continuous surveillance, assessment and approval of factory production control and audit-testing of samples taken at the factory are conformity assessment activities performed once the certificate has been issued.

8.3.2 Initial type testing (ITT)

Minimum requirements for ITT are specified in Appendix D.

8.3.3 Factory Production Control (FPC)

Minimum requirements for FPC are specified in Appendix A.

8.3.4 Inspection and surveillance of the factory and factory production control

8.4 Certificates

Each individual product covered by the certification contract shall have its own unique identifier in the form of the manufacturer’s commercial product name and/or code that appears on the product at the point of sale, and can only be assigned to a single certificate.

More than one individual product may be covered by an individual certificate, but an individual certificate shall not cover products that comply with different technical specifications as presented in 2. An individual certificate may cover products from different production units, lines and plants.

9. Fees

The scheme rules foresee a fee system to cover license fees and the operating cost of the secretariat(-s) involved. The fee system is specified in Appendix E.

Costs covering testing, inspection and assessment between manufacturer and third parties are not governed by the scheme rules, but are negotiated by the contracting parties.

10. Website

The VDI-Mark website is the place where up to date information is found including product data of certified products. It allows a paper free system to an advanced extent. Papers that will remain, such as print outs of certificates, will refer to the web site as the only up to date information.

As the web site only includes official information it is open for reading to all without any password.

The official information on the web site(s) as registered by the scheme web manager includes:

- The scheme rules

- Information on manufacturers and products as found on the product labels, but no information on grouping of products for FPC or audit testing, inspection records and test results.

- Lists of names and addresses for empowered bodies and registered testing laboratories can be found on the web site, but information on the relationship between empowered bodies and test results from comparative testing among laboratories shall not be published.

The layout of the web site and updating of pure text (e.g. scheme rules, announcements) and the list of empowered bodies and testing laboratories is the responsibility of the VDI-Mark scheme web master.

Each certification body is responsible for continuous updating of its own part of the database.

11. Rules for handling complaints, disputes and appeals 11.1 General

All complaints regarding the VDI-Mark scheme, shall be dealt with in accordance with these specific scheme rules, and in accordance with the principles laid down in EN 45011.

(11)

VDI

11

11.2 Complaints about certified products

Complaints about certified products may be lodged with the manufacturer or with the certification body concerned, or with the Quality Assurance Secretariat. In the latter case a copy of the complaint is also sent to the relevant certification body.

The manufacturer of certified products shall:

• keep a record of all complaints relating to a product’s compliance with requirements of the relevant European standard and the manufacturer's performance declaration and make these records available to the empowered organisation when requested;

• take appropriate action in respect of such complaints and any deficiencies found in products or services that affect compliance with the requirements for certification;

• document the actions taken.

The certification body shall ensure that the manufacturer investigates complaints as soon as possible and, where appropriate, advice the complainant of the outcome.

If the investigations of the certification body reveal non-compliance with the requirements of the relevant European standard or these scheme rules, the action arising from the investigation of this complaint is notified by the certification body in a registered letter to the manufacturer.

11.3 Complaints about certification bodies

Complaints regarding the actions of a certification body may be lodged with the certification body

concerned, or with the Quality Assurance Secretariat. In the latter case a copy of the complaint is also sent to the relevant certification body. The certification body shall deal with the complaint using its own complaints procedure, in accordance with the principles laid down in EN 45011. The Quality Assurance Secretariat shall be informed of the complaint and of the outcome and react if needed.

11.4 Disputes about test results

Disputes regarding test results should be addressed to the certification body responsible for the placing of the test work with the laboratory involved. The certification body shall deal directly with the test

laboratory involved using the complaints procedure of the certification body, in accordance with the principles laid down in EN 45011

In the event that a challenge of test results cannot be resolved, e.g. by comparative testing in the presence of the two disputing parties, the arbitration procedure (11.5) shall be followed.

(12)

VDI

12

11.5 Test result arbitration procedure.

The certification body shall take samples as required preferably from the original production in question.

Test specimens from the sample shall be tested for the property in dispute at an agreed 2nd registered laboratory in the presence of both the manufacturer and the certification body. The number of test

specimens tested shall be agreed between parties (e.g. large enough to enable a statistical comparison with the original results). A comparison shall be made between the test results obtained by the initial registered laboratory and the results obtained by the 2nd registered laboratory to detect variations or to confirm similarity (if statistics are used the population shall be the same at a confidence level relevant for the test).

If the second results are seen to be from the same population, the original results will be upheld, even where the result changes the pass/fail assessment.

In the event that the results obtained by the 2nd registered laboratory cannot be confirmed as from the same population as the original results, the results obtained by the 2nd registered laboratory in the presence of both the manufacturer and the certification body shall be used.

Both the manufacturer and the certification body shall have access to the test results from the 2nd laboratory and details of the test procedures used, to enable both parties to investigate any possible non- conformity within their respective systems, and take the appropriate corrective actions.

11.6 Appeals

11.6.1 Appeal to a certification body

The manufacturer may lodge an appeal with the certification body to whom he addressed an application for the right to use the VDI-Mark. The certification body for that purpose maintains its own appeal procedure, in accordance with the principles laid down in EN 45011.

The appeal does not suspend the decision against which it is made.

Appeals can only be related to the certification process carried out by, or under the responsibility of the certification body.

An appeal should be lodged, by registered letter, with the certification body within one month of the formal notification of the contested decision. The certification body shall formally give its answer within one month of receipt of the appeal.

11.6.2 Appeal to the Quality Assurance Secretariat

Manufacturers may lodge an appeal directly with the Quality Assurance Secretariat in the following cases:

• when an appeal is rejected or in case of lack of response by the certification body;

• If the appeal is in respect of the interpretation of the principles contained in this document.

(13)

VDI

13

The appeal procedure does not suspend the decision against which it is made. It shall be notified to the Quality Assurance Secretariat by registered letter, within one month of the formal notification of the contested decision.

In the event of an appeal being addressed by the manufacturer to the Quality Assurance Secretariat, the secretariat prepares a decision within one month of receipt. The decision is formally notified to the

manufacturer and to the certification body by the secretary. The Quality Assurance Secretariat may ask for possible expert assistance/advice by it's choice depending on the actual case

12. Labelling

The labelling of products certified in accordance with these scheme rules may consist of the following marks if requested:

- The CE Marking in accordance with the previsions of the Construction Products Directive (89/106/CEE), complemented by EC Guidance paper D, and with the harmonised product standard (see 2);

- The VDI-Mark, the design of which is shown in Annex 1. The VDI-Mark includes an identification code referring to the Certification Body.

The labelling combining the CE Marking with the VDI-Mark shall be located as specified in the harmonised product standard (see principle of example in Annex 1).

NOTE In addition the VDI-Mark may be licensed for use in conjunction with a mark granted by an empowered/authorised certification body, demonstrating conformity with the European standard.

13. Right to affix the VDI-Mark

After decision of the Management Group the Quality Assurance Secretariat will inform about the authorisation of a certification body for the right to use the VDI-Mark, VDI can conclude a contract with this certification body pursuant to a license agreement.

Formal application for the granting of a licence to use the VDI-Mark is made through signing a contract between the manufacturer and the chosen certification body which sets their relationship, with respect to the implementation of the system for the product(s) concerned.

Only those applicants having obtained a licence to affix the VDI-Mark by means of the procedures laid down in these scheme rules shall be entitled to use the VDI-Mark.
