FOREWORD

- Background of the subject

- Reference documents

Reference documents are referred to within the body of the ETAG and are subject to the specific conditions mentioned therein.

The list of reference documents (mentioning the year of issue) for this ETAG is given in Annex B. When additional parts for this ETAG are written afterwards, they may comprise modifications to the list of reference documents applicable to that part.

Updating conditions

The edition of a reference document given in this list is that which has been adopted by EOTA for its specific use.

When a new edition becomes available, this supersedes the edition mentioned in the list only when EOTA has verified or re-established (possibly with appropriate linkage) its compatibility with the guideline.

EOTA Technical Reports go into detail in some aspects and as such are not part of the ETAG but express the common understanding of existing knowledge and experience of the EOTA-bodies at that moment. When knowledge and experience is developing, especially through approval work, these reports can be amended and supplemented.

EOTA Comprehension Documents permanently take on board all useful information on the general understanding of this ETAG as developed when delivering ETA's in consensus by the EOTA members. Readers and users of this ETAG are advised to check the current status of these documents with an EOTA member.

EOTA may need to make alterations/corrections to the ETAG during its life. These changes will be incorporated into the official version on the EOTA website www.eota.be and the actions catalogued and dated in the associated Progress File

Readers and users of this ETAG are advised to check the current status of the content of this document with that on the EOTA website. The front cover will indicate if and when amendment has taken place.

Section one :

INTRODUCTION

1. PRELIMINARIES

1.1. Legal basis

This ETAG has been established in compliance with the provisions of the Council Directive 89/106/EEC (CPD) and has been established taking into account the following steps:

- the final mandate issued by the EC : 13 July 1999 - the final mandate issued by the EFTA : 13 July 1999 - adoption of the Guideline by the Executive Commission of EOTA : 27 February 2003 - opinion of the Standing Committee for Construction : 14-15 May 2003 - endorsement by the EC : (indicate date)

This document is published by the Member States in their official language or languages according to art. 11.3 of the CPD.

No existing ETAG is superseded. 1.2. Status of ETAG

a. An ETA is one of the two types of technical specifications in the sense of the EC 89/106 Construction Products Directive. This means that Member States shall presume that the approved self-supporting composite lightweight panels are fit for their intended use, i.e. they enable works in which they are employed to satisfy the Essential Requirements during an economically reasonable working life, provided that :

- the works are properly designed and built;

- the conformity of the products with the ETA has been properly attested.

b. This ETAG is a basis for ETAs, i.e. a basis for technical assessment of the fitness for use of a self-supporting composite lightweight panel for an intended use. An ETAG is not itself a technical specification in the sense of the CPD.

This ETAG expresses the common understanding of the approval bodies, acting together within EOTA, as to the provisions of the Construction Products Directive 89/106 and of the Interpretative Documents, in relation to the self-supporting composite lightweight panels and uses concerned, and is written within the framework of a mandate given by the Commission and the EFTA Secretariat, after consulting the Standing Committee for Construction.

c. When accepted by the European Commission after consultation with the Standing Committee for Construction this ETAG is binding for the issuing of ETAs for the self-supporting composite lightweight panels for the defined intended uses.

The application and satisfaction of the provisions of an ETAG (examinations, tests and evaluation methods) leads to an ETA and a presumption of fitness of a self-supporting composite lightweight panel for the defined use only through an evaluation and approval process and decision, followed by the corresponding attestation of conformity. This distinguishes an ETAG from a harmonized European standard which is the direct basis for attestation of conformity.

Where appropriate, self-supporting composite lightweight panels which are outside of the precise scope of this ETAG may be considered through the approval procedure without guidelines according to art. 9.2 of the CPD.

The requirements in this ETAG are set out in terms of objectives and of relevant actions to be taken into account. It specifies values and characteristics, the conformity with which gives the presumption that the requirements set out are satisfied, wherever the state of art permits and after having been confirmed as appropriate for the particular product by the ETA.

ETAG 016

This guideline indicates alternative possibilities for the demonstration of the satisfaction of the requirements.

2. SCOPE

2.1 Scope

This guideline covers self-supporting composite lightweight panels1 with one or both skins made of various organic, mineral or metallic materials assembled, with or without an internal frame and a core which is thermally insulating or not, bonded to at least one of the skins.

The prefabricated panels do not contribute to the loadbearing capacity of the works2. They are used for roofs, external walls, internal walls and ceilings, or claddings of walls, either within a building or as part of a building envelope.

Double metal-skin sandwich panels, covered by prEN 14509, glazing products covered by CEN/TC 129, thermally insulating products covered by CEN/TC 88, masonry products covered by CEN/TC 125, gypsum composite panelscovered by prEN 13950

,

The ETAG is divided into parts: the first part of ETAG deals with general aspects; the other parts deal with specific aspects relating to a different field of application.

Part 1: General

Part 2: Self-supporting composite lightweight panels for use in roofs

Part 3: Self-supporting composite lightweight panels for use in external walls and claddings Part 4: Self-supporting composite lightweight panels for use in internal walls and ceilings

This general part 1 shall be used in conjunction with the relevant specific part(s) relating to the specific intended use(s).

In case the ETA-applicant claims that the composite panel is intended to improve the mechanical resistance or stability of the works, because it supports other structural elements of the works, or because it has a significant positive influence on the racking resistance of the works (horizontally and/or vertically), the product is not covered by this ETA-Guideline.

In that case, and if the composite panel is wood-based, the ETA-Guideline "Stressed-skin load-bearing wood-based panels" shall be used.

2.2 Use categories

See the specific ETAG Parts 2.3. Assumptions

The state of the Art does not enable the development, within a reasonable time, of full and detailed verification methods and corresponding technical criteria/guidance for acceptance for some particular aspects or products. This ETAG contains assumptions taking account of the state of art and makes provisions for appropriate, additional case-by-case approaches when examining ETA-applications, within the general framework of the ETAG and under the CPD consensus procedure between EOTA members.

1

The materials can be as follows:

Skins materials: wood-based sheet, paper, metal foils and sheets (with or without coating), synthetic coatings, gypsum-based sheet, bituminous membranes, fibre-cement sheets; etc.

Core materials: thermally insulating materials, honeycomb materials, glass-fibre tissues, etc.

2

The guidance remains valid for other cases which do not deviate significantly. The general approach of the ETAG remains valid but the provisions then need to be used case by case in an appropriate way. This use of the ETAG is the responsibility of the EOTA body which receives the special application, and subject to consensus within EOTA. Experience in this respect is collected, after endorsement in EOTA-TB, in the ETAG-Format-Comprehension document.

The ETA-applicant has the following possibilities regarding the incorporation of auxiliary products in the ETA (see also chapter 7):

! the incorporation of specific fixings and/or jointing products

In this case, for all the tests where auxiliary products are part of the assembled system, those auxiliary products will be used as specified by the manufacturer. The manufacturer will take full responsibility for those auxiliary products and these products will also be produced under the same attestation of conformity system as indicated in chapter 8 of this ETA-Guideline.

! the reference to generic fixings and/or jointing products

In this case, for all the tests where auxiliary products are part of the assembled system, the auxiliary products used in the tests will be those that conform to the minimum specifications of the manufacturer. These minimum specifications will also be given in the ETA. The ETA will specify clearly that CE marked products should be used, if possible. Where auxiliary products without CE marking are used, the designer should verify the conformity of the auxiliary products with the specifications in the ETA.

3. TERMINOLOGY

3.1. Common terminology and abbreviations (see Annex A) 3.2. Terminology and abbreviations specific to this ETAG Core

Material positioned between two skins. This material can also be a composite material. Self-supporting composite lightweight panel

a prefabricated non-loadbearing panel that, by virtue of its material and shape, will support all applied loadings and transmit these loadings to structural supports.

Joint

Construction formed by the adjacent parts of two or more self-supporting lightweight composite panels, components or building elements. Open joints would render the assembly unable to fulfil some or all the requirements as specified in chapter 4.

Joint product

Building product used to obtain the desired performance of a joint. Skin

Section two :

GUIDANCE FOR THE ASSESSMENT

OF

THE FITNESS FOR USE

GENERAL NOTES

(a) Applicability of the ETAG

This ETAG provides guidance on the assessment of a family of self-supporting composite lightweight panels and their intended uses. It is the manufacturer or producer who defines the self-supporting composite lightweight panels for which he is seeking ETA and how it is to be used in the works, and consequently the scale of the assessment.

In particular a manufacturer needs more than one ETA if :

♦ the family of skin materials is different (metal, polymer, wood-based…), but different materials of the same family are allowed

♦ the family of the core is different (insulating foam, mineral wool, honeycomb …), but different densities and thickness are allowed

Only in the case of the same panel with different end uses a manufacturer will need one ETA which will be split in different chapters, after a common description of the product.

It is therefore possible that for some self-supporting composite lightweight panels, which are fairly conventional, only some of the tests and corresponding criteria are sufficient to establish fitness for use. In other cases, e.g. special or innovative self-supporting composite lightweight panels or materials, or where there is a range of uses, the whole package of tests and assessment may be applicable.

(b) General layout of this section

The assessment of the fitness of self-supporting composite lightweight panels with regard to their fitness for intended use in construction works is a process with three main steps:

Chapter 4 clarifies the specific requirements for the works relevant to the self-supporting composite lightweight panels and uses concerned, beginning with the Essential Requirements for works (CPD art. 11.2) and then listing the corresponding relevant characteristics of self-supporting composite lightweight panels.

Chapter 5:extends the list in chapter 4 into more precise definitions and the methods available to verify product characteristics and to indicate how the requirements and the relevant product characteristics are described. This is carried out by test procedures, methods of calculation and of proof, etc. (selection of the appropriate methods)

Chapter 6 provides guidance on the assessing and judging methods to confirm fitness for the intended use of the self-supporting composite lightweight panels.

Chapter 7, assumptions and recommendations are only relevant in as far as they concern the basis upon which the assessment of the self-supporting composite lightweight panels is made concerning their fitness for the intended use.

ETAG 016

(c) Levels or classes related to the essential requirements and to the product performance (see ID clause 1.2 and EC Guidance Paper E)

According to the CPD, “Classes” in this ETAG refer only to mandatory levels or classes laid down, in the EC-mandate.

This ETAG indicates however the compulsory way of expressing relevant performance characteristics for the self-supporting composite lightweight panels. If, for some uses at least one Member state has no regulations, a manufacturer always has the right to opt out of one or more of them, in which case the ETA will state “no performance determined” against that aspect, except for those properties for which, when no determination has been made, the self-supporting composite lightweight panel does not any longer fall under the scope of the ETAG; such cases shall be indicated in the ETAG.

(d) Working life (durability) and serviceability

The provisions, test and assessment methods in this guideline or referred to, have been written, based upon the assumed intended working life of the self-supporting composite lightweight panels for the intended use of 10 years for the easily replaceable ones, 25 years for others, provided that the self-supporting composite lightweight panel is subject to appropriate use and maintenance (cfr. ch. 7). These provisions are based upon the current state of art and the available knowledge and experience.

An “assumed intended working life” means that it is expected that, when an assessment following the ETAG-provisions is made, and when this working life has elapsed, the real working life may be, in normal use conditions, considerably longer without major degradation affecting the essential requirements.

The indications given as to the working life of a self-supporting composite lightweight panel cannot be interpreted as a guarantee given by the producer or the approval body. They should only be regarded as a means for the specifiers to choose the appropriate criteria for self-supporting composite lightweight panels in relation to the expected, economically reasonable working life of the works (based upon ID. par. 5.2.2).

Specific information on durability aspects will be given in the specific ETAG parts.

(e) Fitness for the intended use

According to the CPD it has to be understood that within the terms of this ETAG, products shall “have such characteristics that the works in which they are to be incorporated, assembled, applied or installed, can, if properly designed and built, satisfy the Essential Requirements” (CPD, art. 2.1). Hence, the self-supporting composite lightweight panels must be suitable for use in construction works which (as a whole and in their separate parts) are fit for their intended use, account being taken of economy, in order to satisfy the essential requirements. Such requirements must, subject to normal maintenance, be satisfied for an economically reasonable working life. The requirements generally concern actions which are foreseeable. “(CPD Annex I, preamble).

4 REQUIREMENTS

for works, and their relationship to the characteristics of self-supporting

composite lightweight panels

This chapter sets out the aspects of performance to be examined in order to satisfy the relevant Essential Requirements, by:

expressing in more detail, within the scope of the ETAG, the relevant Essential Requirements of the CPD in the Interpretative Documents and in the mandate, for works or parts of the works, taking into account the actions to be considered, as well as the expected durability and serviceability of the works.

Applying them to the scope of the ETAG (product and where appropriate its constituents, components and intended uses), and providing a list of relevant characteristics of self-supporting composite lightweight panels and other applicable properties.

When a product characteristic or other applicable property is specific to one of the Essential Requirements, it is dealt with in the appropriate place. If, however, the characteristic or property is relevant to more than one Essential Requirement, it is addressed under the most important one with cross reference to the other(s). This is especially important where a manufacturer claims “No performance determined” for a characteristic or property under one Essential Requirement and it is critical for the assessing and judging under another Essential Requirement. Similarly, characteristics or properties which have a bearing on durability assessments may be dealt with under ER 1 to ER 6, with reference under 4.7. Where there is a characteristic which only relates to durability, this is dealt with in 4.7

This chapter also takes into account further requirements, if any (e.g. resulting from other EC Directives) and identifies aspects of serviceability including specifying characteristics needed to identify the self-supporting composite lightweight panels. (cfr ETA-format par. II.2).

7. ASSUMPTIONS AND RECOMMENDATIONS UNDER WHICH THE FITNESS

FOR USE OF THE PRODUCTS IS ASSESSED

This chapter sets out the assumptions and recommendations for design, installation and execution, packaging, transport and storage, use, maintenance and repair under which the assessment of the fitness for use according to the ETAG can be made (only when necessary and in so far as they have a bearing on the assessment or on the products).

7.1 Design of works

7.1.1 General assumptions

The design of a self-supporting lightweight composite panel, in many important respects, will be specific to the works in which it is to be used.

The following is a brief list of aspects, which need to be taken into account when designing the works, with respect to the self-supporting lightweight composite panel; the list is not exhaustive:

! Permissible deflections under various loads, e.g. wind, snow load

! Permissible deflection limits for the panels and of the adjacent structural parts

! Where and how the self-supporting lightweight composite panel is fixed to the rigid support(s)

! Fire protection

! Assessment of condensation risk

! Sound insulation

! Provisions of vapour control and thermal insulation

! Thermal inertia

! Attachments, fixtures and penetrations

! Means of access for inspection and maintenance.

The ETA will indicate the conditions for design of the particular self-supporting lightweight composite panel into the works. It is for the designer to ensure that the self-supporting composite lightweight panel as installed in the works will provide the required performance on the basis of the information given in the ETA. It has to be taken into account that the determination of mechanical resistance is based on single test measurements, therefore the designer may apply the relevant safety factors according to national practice and for particular use.

When appropriate, special fixings for seismic conditions need to be foreseen. In dynamic actions, such as those occurring in an earthquake, the designer shall take account of the possible contribution of the self-supporting lightweight composite panel in accordance with national or local regulations.

7.1.2 Assumptions regarding the substrate, support or supporting frame

The assessment of the self-supporting lightweight composite panels shall be carried out under the presumption that the substrate, support or the supporting frame will not jeopardise any of the ERs in an assembled system.

7.1.3 Assumptions regarding auxiliary products 7.1.3.1 General

Auxiliary products need to fulfil specifications for the panel, used in an assembly, to meet the performance characteristics as specified in the ETA-Guideline.

For generic auxiliary products, the ETA-applicant needs to specify minimum criteria, which the generic auxiliary product should fulfil.

If the ETA-applicant chooses to specify specific auxiliary products, those products should be clearly identified and tested and the test results specified in the ETA.

7.1.3.2 Verification methods for fixings

The performance characteristics for fixings should be verified in accordance with European technical specifications for the fixings under consideration:

! harmonised European product standards as published by CEN, or

! European Technical Approvals as published by EOTA-member bodies.

If such technical specifications are not available, the specifications referred to in this paragraph shall be used for verification purposes.

7.1.3.2.1 Reaction to fire

The fixings shall be tested as a part of the panel assembly (see §5.2.1). 7.1.3.2.2 Release of dangerous substances

See § 5.3.3

7.1.3.2.3 Mechanical resistance and stability (of fixings)

This test method establishes the pull-out resistance of a fixing. This test will be conducted on each substrate for which the panels are intended to be used.

The test is carried out on five sample substrates, each measuring at least 300mm ± 20mm. The apparatus consists of:

! a dynamometer,

! a support as shown in Figure 1.

The substrates and fixings are conditioned for at least 2h at 23 ± 2°C before the test. The fixings are installed in accordance with the manufacturer's specifications.

The test will be carried out at 23 ± 2°C. The tensile strength for pulling out the fixing shall be measured with a dynamometer. The tensioning speed is 20 mm/min.

The pull-out resistance of each test is expressed in N. The test results and mean value is recorded in the test report, the ETA will specify the mean value of the five results.

Figure 1: pull-out resistance test 7.1.3.2.4 Durability requirements

The behaviour of fixings can be influenced by corrosion and the degradation of the coating. Therefore, the following shall be considered:

7.1.3.2.4.1 Corrosion

If the fixing is to be used in particularly aggressive conditions, such as chloride atmosphere of indoor swimming pools or atmosphere with extreme chemical pollution, special considerations including testing are necessary, taking into account the environmental conditions and the available experience.

7.1.3.2.4.2 Coating

The durability of the coating that ensures the suitability and the bearing behaviour of the fixing shall be shown.

Special test conditions cannot be given in this ETA-guideline for checking the durability of a coating because they vary depending on the type of coating. Appropriate tests should be decided on by the responsible approval body.

The following environmental conditions should be taken into account in assessing the durability of coatings:

Dry internal conditions

! high alkalinity (pH > 13.2)

! temperature in range of - 5°C to + 40°C. Other environmental conditions

ETAG 016

Zinc coatings (electroplated or hot-dip galvanised) need not be subjected to testing if used under dry internal conditions.

7.1.3.2.5 Identification

During tests on the fixings, the following properties shall be determined: tensile strength, elastic limit, elongation at rupture and hardness. The measured values shall be compared with minimum values or strength classes indicated in European or ISO standards.

For the testing of carbon steel screws, bolts, nuts and threaded cones, reference can be made to ISO 898, Parts 1 and 2.

For the testing of stainless steel screws reference can be made to ISO 3506. For quenched components, the surface hardness and case depth are to be determined. Hardness testing shall be carried out by either the Brinell or Vickers method. Wherever possible, the material declaration, according to the relevant material standard, should be provided.

If appropriate, surface condition, e.g. surface roughness and the type and thickness of any protective coating, shall be measured.

The results obtained shall be assessed to ensure that they are within the manufacturer’s specification.

7.1.3.3 Verification methods for jointing materials (sealants and gaskets)

The performance characteristics for jointing materials should be verified in accordance with European technical specifications for the jointing materials under consideration:

! harmonised European product standards as published by CEN, or
