Legal basis This Guideline for European Technical Approvals has been established in full compliance with the provisions of the Council Directive 89/106/EEC (CPD) and has been established taking into account the following steps: 16 April 1998 • Issuing of the final mandate by the EC: Issuing of the final mandate by EFTA: 16 April 1998 • 13 October 1999 • Adoption of the Guideline by EOTA: (Executive Commission) Endorsement of the document by the EC: SCC opinion of 9-10 December 1999 • EC letter of 11 August 2000 idem • Endorsement of the document by EFTA: This document is published by the Member States in their official language or languages according to Art. 11/3 of the CPD No existing ETA-Guideline is superseded.
Status of the ETA-Guidelines An ETA is one of the two types of technical specifications in the sense of the CPD, which means that Member States shall presume the approved products fit for their intended use, e.g. that 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. An ETA-Guideline is a basis for ETAs, that is a basis for technical assessment of the fitness for use of a product for an intended use. *) ETA-Guidelines express the common understanding of the Approval Bodies of the provisions of the EC-Construction Products Directive 89/106 (CPD) and of the Interpretative Documents to the CPD, with regard to the products and uses concerned, established within the framework of a mandate given by the Commission after consulting the EC-Standing Committee for Construction.
ETA-Guidelines are binding for the issuing of ETAs of the products concerned for an intended use, when accepted by the EC-Commission after consultation with the Standing Committee for Construction and published by the Member States in their official language or languages. *) An ETA-Guideline is not in itself a technical specification in the sense of the CPD.
ETAG 005-1 Page 7
The applicability to, and the satisfaction of, the ETA-Guideline for a product and its intended use have to be assessed in a case-by-case evaluation by an authorised Approval Body. Satisfaction of the provisions of an ETA-Guideline (examinations, tests and evaluation methods) leads to a presumption of fitness for use only through this case-by-case evaluation. Products outside of the scope of an ETA-Guideline may be considered, where appropriate, through the approval procedure without guidelines according to Art. 9.2. of the CPD. The requirements in ETA-Guidelines are set out in terms of objectives and of relevant actions to be taken into account. ETA-Guidelines specify values and characteristics, the conformity with which gives the presumption that the requirements set out are satisfied, whenever the state of art permits. The ETA-Guidelines may indicate alternate possibilities for the demonstration of the satisfaction of the requirements.
This ETA-Guideline Part 1: General specifies the terminology and definitions, classification, categorisation, requirements, methods of verification, assessment procedures, product characteristics, attestation of conformity and content of the ETA for liquid applied roof waterproofing kits (LARWK). It also gives guidance for the assessment of the application methods and design rules, based on the present "State of the Art". Consequently it will be updated in case of justifiable reasons. This ETA-Guideline is applicable to in-situ applied liquid roof waterproofing kits which, as an assembled system being part of the works, are supposed to meet the Essential Requirements for a period of: a - 5 years as indicated by the Applicant for ETA b - 10 years; c - 25 years as indicated by the Applicant for ETA This ETA-Guideline is NOT applicable to LARWK(s) for use on roofs accessible to vehicles. This ETA-Guideline Part 1 - General shall be used in conjunction with one of the Complementary Parts which amplifies the scope with respect to a particular family of products.

SECTION TWO GUIDANCE FOR THE ASSESSMENT OF THE FITNESS FOR USE
General This chapter identifies the aspects of performance to be examined to satisfy the relevant Essential Requirements, by: i) expressing in more detail, and in terms applicable to the scope of the guideline, the relevant Essential Requirements of the CPD (given concrete form in the Interpretative Documents and further specified in the mandates), for works or parts of works, taking into account the durability and serviceability of the works, and ii) applying them to the scope of the ETA-Guideline (product/system and intended use), and indicating the relevant product characteristics and eventually other aspects (see 4.7). The aspects of performance to be examined to satisfy the Essential Requirements, as defined by the CPD and amplified by the appropriate ID, relevant to LARWKs are summarised in Table 1. Table 1 - Relationship between the ER, ID and aspects of performance ID reference Performance of the Works Performance of the Products 4.2.4 : Limitation of spread of fire to neighbouring construction works 4.2.4.1 : Statement of principle 4.2.4.2 : Parts of works concerned (a) – roof coverings 4.3.1.2 : Products for roofs subject to fire requirements 4.3.1.2.2 : Roofs exposed to an external fire 4.3.2 : Performance of products ETA-Guideline Clause reference (see table 7) 4.2.1 : Roofs exposed to an external fire 4.2.2 : reaction to fire

Part 1 of this Guideline shall be used in conjunction with one of the Complementary Parts which amplify the requirements in the context of a particular family of products. The assessment of fitness for use is made on the assumption that the LARWK is installed, used and maintained in accordance with the specifications laid down by the Applicant, lodged with, accepted and registered by the Approval Body.
ER1: Mechanical resistance and stability Liquid applied roof waterproofing kits (LARWK), as an assembled system, make no contribution towards enabling a construction works to meet the requirements of ER1 Mechanical resistance and stability. There are therefore no requirements.
ER2: Safety in case of fire The Essential Requirement laid down in the Council Directive 89/106/EEC is as follows: The construction works must be designed and built in such a way that in the event of an outbreak of fire: the load bearing capacity of the construction can be assumed for a specific period of time the generation and spread of fire and smoke within the works are limited the spread of fire to neighbouring construction works is limited occupants can leave the works or be rescued by other means the safety of rescue teams is taken into consideration The following aspects of performance are relevant to this Essential Requirement for Liquid Applied Roof Waterproofing Kits:
External fire performance The external fire performance of the roof of which the applied roof waterproofing kit form part shall be in accordance with laws, regulations and administrative provisions applicable to the roof of which the applied roof waterproofing kit form part in its intended end use application. This performance shall be expressed in the form of a classification specified in accordance with the relevant EC decision and the appropriate CEN classification standards. Reaction to fire The reaction to fire performance of the liquid applied roof waterproof kit as applied as an assembled system shall be in accordance with laws, regulations and administrative provisions applicable to the liquid applied roof waterproof kit as applied as an assembled system in its intended end use application. This performance shall be expressed in the form of a classification specified in accordance with the relevant EC decision and the appropriate CEN classification standards. Working Life, Durability Compliance with the Essential Requirement throughout the working life requires that, during the intended use, the assembled system remains undamaged and that the properties are not subject to unacceptable changes due to external agencies in such a way as to affect the reaction to fire and the external fire performance of the assembled system.
ETAG 005-1 Page 13
ER3: Hygiene, health and the environment Indoor environment In conjunction with the other elements of the roof construction, an assembled system of a LARWK shall control the ingress of moisture from the outside into the building, in both liquid and vapour form, to control the presence of damp in parts of the works or on surfaces within the works. Outdoor environment Release of dangerous substances The product/kit must be such that, when installed according to the appropriate provisions of the Member States, it allows for the satisfaction of the ER3 of the CPD as expressed by the national provisions of the Member States and in particular does not cause harmful emission of toxic gases, dangerous particles or radiation to the indoor environment nor contamination of the outdoor environment (air, soil or water).
4.3.2 4.3.2.1.
Working Life, Durability Compliance with the Essential Requirement throughout the working life requires that, during the intended use, the assembled system remains undamaged and that the properties are not subject to unacceptable changes due to external agencies. The assembled system shall be resistant to the effects of: i) ii) iii) iv) v) vi) wind loads; mechanical damage; movement; surface temperature extremes during use; ageing media, including heat, UV radiation and water; plant roots
ER4: Safety in use Resistance to wind load The assembled system of a LARWK shall have sufficient mechanical resistance and stability against wind loads to avoid detachement of parts of the work that, by falling down, might form the risk of injury or death of users in or around the work. The aspects of performance that can influence the meeting of the Essential Requirements are dealt with under ER3 - Hygiene, health and the environment. (see 4.3.1 Indoor environment and 4.3.3 Working life / durability)
Slipperiness The surface of the LAWRK shall not be slippery due to either the inherent surface conditions or the presence of water or grease on the surface so that it will influence the probability of falling after slipping and thereby causing a risk for the occupants/users. Working life, durability Compliance with the Essential Requirement throughout the working life requires that, during the intended use, the assembled system remains attached. This aspect is dealt with under ER3 – Hygiene, health and the environment (see 4.3.3 Working life / durability) ETAG 005-1 Page 14
ER5: Protection against noise The assembled system of a LARWK makes no contribution towards enabling a construction works to meet the requirements of ER5 - Protection against noise. There are therefore no requirements.
ER6: Energy economy and heat retention The assembled system of a LARWK makes no direct contribution towards enabling a construction works to meet the requirements of ER6 - Energy economy and heat retention. There are therefore no requirements. The aspects of performance related to moisture ingress that can influence the meeting of this Essential Requirement are dealt with under ER3 - Hygiene, health and the environment. (See 4.3.1 Indoor environment.)
4.7 4.7.0
Related aspects of serviceability General Account shall be taken of all aspects of use, specification and expected working life that will affect the assessment of fitness for use at the local level. These will include climatic zone in which the assembled system of a LARWK will be used (influencing surface temperatures, levels of UV radiation, durability etc.), accessibility and slope of the roof etc. This will necessitate the use of categorisations for the systems. Effects of application conditions Where the Applicant declares a range of permitted weather conditions or permits variations in proportions and/or the nature of constituent parts, it must be verified that the LARWK and its assembled system satisfies the performance requirements over the whole range of conditions. Classification according to safety in case of fire General The Applicant shall classify each of the kits according to clause 4.7.2.2. Classification will facilitate the assessment of fitness for use of the assembled system and the satisfaction of the Essential Requirement where differences in performance are expected due to reaction to fire. The declared classifications shall be taken into account in the verification of performance against the Essential Requirement ER2.
4.7.2 4.7.2.0
Classification according to external fire performance. Classification of the LARWK with respect to external fire performance is undertaken in accordance with prEN 13501-5. Commission Decision 2000/553/EC shall be taken into account.
Classification according to reaction to fire Classification of the LARWK with respect to reaction to fire is undertaken in accordance with: EN 13501-1: Reaction to fire - Classification The following range of Euroclasses is used: ETAG 005-1 Page 15
A1, A2, B, C, D, E, F 4.7.3 4.7.3.0 Categorisation according to use General The Applicant shall categorise each of his kits according to the categories given in 4.7.3.1 to 4.7.3.5. Categorisation will facilitate the assessment of fitness for use of the assembled systems and of the satisfaction of the Essential Requirements for different expected working lives or where differences in performance are expected due to the intended use. The declared categorisation shall be taken into account in the verification of performance against the Essential Requirements. Categorisation according to working life This Guideline is written on the assumption that the estimated working life of assembled systems for the intended use is 10 years. In special circumstances, where indicated by the Applicant, this may be modified to 5 or 25 years. An estimated working life of assembled systems of 5 years shall only be assumed in the case of LARWKs intended for use as a repair, renovation or maintenance medium only, or for use solely in construction works which have a limited intended life. An estimated working life of 25 years shall only be assumed in the case where the Applicant can offer, for examination by the Approval Body, examples of satisfactory use of that assembled system for a period of at least 5 years in a relevant situation and/or climate. All product specifications and assessment methods shall take account of this expected working life of 25 years. The categories according to working life are given in Table 2. Table 2 - Categorisation according to working life Category W1 Expected working life (years) 5 Category W2 10 Category W3 25
The indication given on the working life of assembled system(s) cannot be interpreted as a guarantee by the Applicant (or the Approval Body) but is regarded only as a means of choosing the appropriate products in relation to the expected economically reasonable working life of the works (ID par. 5.2.2). 4.7.3.2 Categorisation according to climatic zone of use The assembled system, including its support and protection (if any) shall be resistant to the solar exposure effects (solar energy, temperature, etc) occurring during its expected working life which will depend on the geographical location of use. Two categories of climatic zone have been established (Moderate and Severe) and the limiting values for mean annual radiant exposure and the mean air temperature during the warmest month are defined in Table 3. Table 3 - Categorisation according to climatic zone Category M Moderate climate Category S Severe climate
ETAG 005-1 Page 16
Annual radiant exposure on horizontal surface Average temperature of the warmest month per year
< 5 GJ/m and < 22°C
≥ 5 GJ/m and/or ≥ 22°C
Note 1: The annual radiant exposure is the total amount of solar energy received by horizontal global surface within a defined geographical region, calculated as a mean measured value over a period of five years. The average temperature of the warmest month is the calculated mean value over a period of five years for the average measured maximum air temperature of that month. Note 2: The "isoline 5" (see map of TR-010.C - mean UV radiant exposure) can be used as an indicative dividing line between "moderate" and "severe" climatic zones of use, related to temperatures. For a Category M kit to be suitable for use in a particular location both the parameters at that location (derived from national meteorological statistics) shall comply with the limiting values given in Table 3. If one of the parameters exceeds the limiting values for Category M then only kits of Category S may be used. The appropriate climatic zone category required may be declared by Member States [see CPD art. 3(2)]. Kits assessed as fit for use only in the Moderate zone may not be used in those climates categorised as Severe for the same expected working life. 4.7.3.3 Categorisation of user loads The assembled systems, including their support and protection (if any), shall be capable of withstanding mechanical damage due to the user loads likely to occur during their working life. The risk of mechanical damage will depend on the accessibility of the roof and the frequency of the traffic envisaged. The appropriate categories of user loads and examples of the related accessibility are given in Table 4.
Table 4 - Categorisation according to user loads Category P1 P2 P3 P4 Low Moderate Normal Special User load Examples of accessibility non-accessible accessible for maintenance of the roofing only accessible for maintenance of plant and equipment and to pedestrian traffic roof gardens, inverted roofs, green roofs
ETAG 005-1 Page 17
Categorisation of roof slope The assembled system, including its support and protection (if any), shall be capable of withstanding the effects originating from its slope. The appropriate categories of roof slopes and examples of the related effects which can influence the fitness for use are given in Table 5.

General The methods of verification given in this section shall be applied, where appropriate, to the kits proposed by the Applicant. Where possible the Approval Body shall select the kits and levels to be tested so that extrapolation and interpolation are possible, thereby reducing the number of necessary tests. In general a satisfactory performance at a severe level will assure acceptance at a less severe level. It is the responsibility of the Approval Body to identify the most unfavourable conditions e.g. thickness of samples etc.. Reference shall also be made to the appropriate Complementary Part relevant to the family of products which may identify tests omitted or include additional requirements specific to that family of products. The verification of performances shall take into account the declared classification and categorisation of the kit(s) and may also include inspection of existing works. The relationship between the requirements as defined in clause 4, the product performance and the methods of verification listed below, are summarised in Table 7. Identification (1)Depending upon the nature and type of products, the text of the ETAG shall provide indications as to how products shall be identified for approval and other purposes. However what is written shall be flexible because of differences in manufacturing techniques, the possible range of sizes of factories/manufacturing facilities, size of batches and amount of product produced in a given time. (2) Example techniques and procedures to be considered either individually or in combination (not exhaustive) • Fingerprinting (infrared, gas chromatography, ……………..) • Formulation (chemical constitution, recipes, composition of raw materials, amounts, components specified by characteristics, compliance with other specifications eg. ENs or by weight, volume, percentage……………..) • Manufacturing process parameters (temperature, pressure, time … product/production codes) • Testing of physical characteristics - data (geometry, density, mechanical strength…………) Calculations, detailing, drawings • (3) Whichever method(s) is/are used it is necessary to recognise practical tolerances in relation to results/data collected. (4) It is however also essential that these techniques/methods shall be introduced only as far as they have or could have an influence on the fulfilment of the Essential Requirements, including aspects of durability.

ER 2: Safety in case of fire External fire performance The Liquid Applied Roof Waterproofing Kit as an assembled system shall be tested using the method relevant for the corresponding external performance roof class, in order to be classified according to pr EN 13501-5[1]. External fire performance cannot be claimed for individual products alone, since it is a characteristic of a complete roof system. When the product is not a kit, the manufacturer will need to fully define the assembled system of which the product will form part in order to make any external fire performance claim. The liquid applied roof waterproofing kit as an assembled system, may form as part of a roof, may be considered “deemed to satisfy” all the provisions for external fire performance of all National regulations of the Member States without the need for testing. This on the basis that is included within the definitions given Commission Decision 2000/553/EC and provided that any national provisions on the design and executions of works are fulfilled. Where more than one assembled system is possible for an individual Liquid Applied Roof Waterproofing Kit a minimum of one ‘typical’ roof system shall be tested in accordance with ENV 1187:2002, except where the assembled system can be classified without further testing (CWFT) [2]. All other possible assembled systems shall be Classified as ‘No Performance Determined’. This does not prelude the possibility of other assembled systems being tested, at the request of the manufacturer. [2] Where assembled systems are protected by a durable protection layer, the external fire performance can be controlled by the nature of this protection layer. Therefore verification of the external fire performance may be omitted, provided the effect of the protection layer is assessed and/or stipulated by Commission Decision (2000/553/EC).
Reaction to fire The liquid applied roof waterproof kit as an assembled system shall be tested, using the test method(s) relevant for the corresponding reaction to fire class, in order to be classified according to EN 13501-1:2002. Details are given in Annex IV, Reaction to Fire – Test Procedures
ER3: Hygiene, health and the environment Indoor environment Resistance to water vapour To establish the resistance to the passage of water vapour through the assembled system, the water vapour permeability of the assembled system shall be determined in accordance with EN 1931, using a free sample according to Annex III.4. The value shall be declared by the Applicant and verified by the Approval Body. From this value the water vapour resistance shall be calculated for use in the design of the roof. Watertightness The watertightness of the assembled system shall be determined by testing in accordance with the test method given in EOTA technical report TR 003. Release of dangerous substances – Presence of dangerous substances in the product The applicant shall submit a written declaration stating whether or not the product/kit ETAG 005-1 Page 23
contains dangerous substances according to European and national regulations, when and where relevant in the Member States of destination, and shall list these substances. 5.3.2.2 – Compliance with the applicable regulations If the product/kit contains dangerous substances as declared above, the ETA will provide the method(s) which has been used for demonstrating compliance with the applicable regulations in the Member States of destination, according to the dated EU data-base (method(s) of content or release, as appropriate). – Application of the precautionary principle An EOTA member has the possibility to provide to the other members, through the Secretary General, warning about substances which, according to Health authorities of its country, are considered to be dangerous under sound scientific evidence, but are not yet regulated. Complete references about this evidence will be provided. This information once agreed upon, will be kept in an EOTA data base, and will be transferred to the Commission services.
The information contained in this EOTA data base will also be communicated to any ETA applicant. On the basis of this information, a protocol of assessment of the product, regarding this substance, could be established on request of a manufacturer with the participation of the Approval Body which raised the issue.
5.3.3 5.3.3.0 i)
Working Life, Durability General Previous use For kits categorised W3 (25 years) the Approval Body shall take into account, by examination where appropriate, existing examples of use of the assembled system. Such examples of the assembled system shall be: a) in the same, or more severe categorisation as that required for the kit to be assessed and b) as old as possible, with a minimum of 5 years. Where such examples of previous use are not available, it may be possible to utilise existing knowledge of the performance on sites of assembled systems from the same family of products, meeting the above conditions. The Approval Body shall satisfy itself that such indirect evidence of previous use is applicable to the kit under assessment.
Durability assessment The procedures given in sections 5.3.3.1 to 5.3.3.6 are based on performance tests. To obtain a more complete assessment of durability, changes in material characteristics after exposure to ageing media shall be examined. Ageing media used shall be as described in 5.3.3.5 with the possibility of performing tests on intermediate time periods. The methods of verification for the relevant material characteristics are given in the Complementary Parts. The nature of the substrate may influence the durability of the assembled system. Therefore the compatibility of the assembled system with the substrate shall be assessed. This may be done by comparative testing before and after ageing by water or heat.
Resistance to wind loads To continue to comply with the Essential Requirements the assembled system shall resist ETAG 005-1 Page 24
the effects of wind loads. i) If the assembled system is loose laid and ballasted the resistance to wind loads is provided by the mass of the ballast used. Verification of performance shall be based on calculations of the mass of ballast and the weight of the system. Note: Information in that respect can be obtained from national regulations or from EN 1990 together with ENV 1991-2-4. The resistance to wind loads of partially or fully bonded assembled systems shall be verified by measuring the delamination strength at 23°C in accordance with the test method given in EOTA technical report TR-004 for all proposed substrates. In the case of a assembled system incorporating a partially bonded supporting layer, a wind uplift test in accordance with the method given in EOTA technical report TR-005 shall be performed. This test shall be performed on the substrate giving the lowest delamination strength at 23°C {see (ii) above}. Verification of performances of mechanically fastened supporting layer, including the durability of the fasteners, will be covered by guideline 006 - MEFAWAME (Systems of Mechanically Fastened Flexible Roof Waterproofing Membranes). Resistance to mechanical damage (perforation) The resistance to mechanical damage shall be verified by subjecting the assembled system to dynamic indentation and to static indentation. Resistance to dynamic indentation The resistance to dynamic indentation at 23°C shall be determined in accordance with the test method given in EOTA technical report TR-006, using the indentor size appropriate to the level of performance required and defined by the relevant user load category (see Table 4). The relationship between the user load category and the levels of resistance to dynamic indentation is given in Table 8. These tests shall be performed on the most and least compressible of the substrates specified by the Applicant for the kit in question. 5.3.3.2.2 Resistance to static indentation The resistance to static indentation at 23°C shall be determined in accordance with the test method given in EOTA technical report TR-007, using the load appropriate to the level of performance required and defined by the relevant user load category (see Table 4). The relationship between the user load category and the levels of resistance to static indentation is given in Table 8. These tests shall be performed on the most and least compressible of the substrates specified by the Applicant for the kit in question.

5.3.3.4.2 Extreme low temperatures For kits categorised according to minimum surface temperature TL 4 (see Table 6(a)) the crack bridging capability of the assembled system shall be determined according to the method given in EOTA technical report TR-013 at a temperature of - 30° C.
5.3.3.4.3 High temperatures i) The effect of the maximum surface temperatures on the resistance to wind load shall be determined by performing the delamination strength test in accordance with the method given in EOTA technical report TR-004 at a temperature of + 40°C. ii) The effect of the maximum surface temperatures on the resistance to mechanical damage shall be determined by performing the static indentation test in accordance with the method given in EOTA technical report TR-007 on the least compressible substrate at the appropriate ETAG 005-1 Page 26
maximum surface temperature (see Table 6(b)) and the level of resistance (see Table 8), defined by the categorisation of the kit. iii) The effects of high temperatures on the stability of assembled systems from kits categorised S3 and S4 only, shall be determined by performing the resistance to sliding test in accordance with the method given in EOTA technical report TR-009 at the appropriate maximum surface temperature defined by the categorisation of the kit (see Table 6(b)) and at the maximum slope as defined by the categorisation of the kit according to roof slope (see Table 5). This test is not required for assembled systems from kits categorised according to slope as S1 or S2. However for all kits used on vertical or near vertical parts of details, this test shall be performed at a slope of 90°. iv) Where an assembled system contains a supporting layer which is not fully bonded, the effects of high temperatures are governed by the dimensional stability of that supporting layer. Measurement of the dimensional stability of the supporting layer shall be part of the identification of components, elaborated in the relevant Complementary Part.
5.3.3.5 Resistance to ageing media 5.3.3.5.1 Resistance to heat ageing i) The effects of heat ageing on the resistance to mechanical damage shall be verified by subjecting an assembled system (according to Annex III) to heat ageing in accordance with o EOTA technical report TR-011 at 80 +/- 2 C for a period defined by the categorisation according to climatic zone (see Table 3) and the categorisation according to expected working life (see Table 2). The relationship between these aspects and the period of exposure is given in Table 10. Depending on the nature of different families of products specific ageing conditions, defined in the relevant Complementary Part, may apply. Table 10 - Relationship between climatic zone, working life and period of exposure to heat. Climatic zone category Working life category Exposure period (days) W1 25 Moderate (M) W2 50 W3 100 W1 50 Severe (S) W2 100 W3 200
Following the heat ageing period the resistance to dynamic indentation at the surface temperature according to the TL categorisation as defined in 5.3.3.4.1 (i) shall be performed. ii) The effects of heat ageing on the resistance to fatigue movement of fully bonded assembled systems shall be verified by subjecting an assembled system (according to Annex III) to heat ageing in accordance with EOTA technical report TR-011 at 80 +/- 2°C for a period defined by the categorisation according to the climatic zone (see Table 3) and the categorisation according to expected working life (see Table 2).

Additional specific verification after heat ageing Any additional characteristic as defined in the appropriate Complementary Part shall be measured following the heat ageing/UV ageing/water ageing period.
5.3.3.5.2 UV radiation in the presence of moisture The effects of ageing by UV in the presence of moisture shall be determined by testing the defined characteristics of the assembled system before and after subjecting it to artificial weathering according to the exposure procedure defined in EOTA technical report TR-010. The precise exposure conditions are determined by the categorisation to climatic zone of the kit (see Table 11); the radiant exposure is related to the categorisation to expected working life.
Table 11 - Relationship between categorisation to climatic zone and UV-exposure conditions Categorisation to climatic zone (see table 3) Category "M" Category "S" Exposure conditions (see EOTA technical report TR-010) Conditions "M": UV + spraying Conditions "S": UV + spraying

Any classification relates only to the roof tested so the ETA shall define clearly the build-up of the roof receiving the classification.
6.2.1.2 Where appropriate roofs may be classified in accordance with the EC Decision 2000/553/EC without the need for testing. The ETA shall define clearly the build-up of the roof(s)) that is (are) subject to classification without further testing. The ETA shall also draw to the attention of Regulators that all other possible assembled systems are classified as ‘No Performance Determined’ and shall note that these assembled systems should be assessed or tested prior to use, on a case by case basis.[1] It will be up to the Regulators in each Member State to decide what additional assessment or testing shall be required before the use of ‘no performance determined ’ assembled systems is permitted. 6.2.2 Reaction to fire The product/kit and/or components shall be classified according to EN 13501-1:2002.
ER3: Hygiene, health and the environment Indoor environment Resistance to moisture vapour The resistance of moisture vapour, calculated on the basis of the declared value for water vapour permeability of the assembled system, shall be such that a user of the product is able to carry out the necessary hygrothermal analysis to ensure that the roof is capable of meeting the Essential Requirement. The value for water vapour resistance, assessed by the Approval Body, shall be within the range as declared by the Applicant.
Watertightness After testing in accordance with 5.3.1.2 the assembled system(s) shall be watertight.
Release of dangerous substances The product/kit shall comply with all relevant European and national provisions applicable for the uses for which it is brought to the market. The attention of the applicant should be drawn on the fact that for other uses or other Member States of destination there may be other requirements which would have to be respected. For dangerous substances contained in the product but not covered by the ETA, the NPD option (no performance determined) is applicable.
ETAG 005-1 Page 34
The ETA shall indicate whether or not the assembled system of the LARWK contains restricted or prohibited products, according clause 5.3.2. When an assembled system does contain restricted or prohibited substances, this shall be identified by nature and content If chemicals are added to prevent root penetration this chemicals shall be listed in consideration to Biocide Directive (Directive 98/8/EC) in the ETA. 6.3.3 6.3.3.0 Working life, durability General The guidance given on the assessment of working life is based on the ‘state of the art’ and a knowledge of current products within the defined family of products. It is possible that, during the assessment of a product, an Approval Body may obtain information which gives concerns relating to the durability of that product, despite the guidance given. In such cases the Approval Body, in consultation with Working Group 4.02/01, may require additional justification relating to the expected working life of the product. This may include additional testing, additional evidence of satisfactory performance in use, etc.. The Approval Body shall satisfy itself that the expected working life, based on the data gathered in accordance with 5.3.3.0 (ii), is consistent with the defined working life category. Note: the data gathered will be reviewed and, in the light of experience, may enable the recommendation of specific requirements. 6.3.3.1 Previous use For kits categorised "W 3" (25 years), the evidence of previous use of the assembled system (or similar systems) for a minimum period of 5 years shall demonstrate continued satisfactory performance. The Approval Body shall be satisfied that the existing use in terms of categorisation (eg situation, climatic zone, etc.) is relevant to the proposed use. Resistance to wind loads In the case of loose laid and ballasted assembled systems the mass of the proposed minimum thickness of ballast layer shall be declared in the ETA to enable the user to judge whether or not the assembled system is suitable for use under local conditions. If the Applicant proposes a calculation method to enable unrestricted use, this shall be declared in the ETA and included in the Manufacturer's Technical Dossier. ii) The delamination strength of partially or fully bonded assembled systems determined in accordance with 5.3.3.1 (ii) shall exceed 50 kPa. Note: The value of 50 kPa is derived from the maximum load applied by wind. In practice the delamination strength will be significantly in excess of this load. The wind uplift resistance, determined in accordance with 5.3.3.1 (iii), shall be declared in the ETA to enable the user to judge whether or not the assembled system is suitable for use under local conditions.

The level of Attestation of Conformity then shall be 1. Concerning table 17 footnote *** this is not applicable for the liquid applied roof waterproofing kits because all the products are based on organic material and therefore not covered by the Commission Decision 96/603/EC and its amendment. Due to their properties with regard to the uses subject to regulations on roof waterproofing use, external fire performance and reaction to fire, uses different AoC systems as stated before shall be applied to the products. That means for the performance of AoC for the product that only the product properties related to these uses shall be evaluated according to the relevant AoC system. The tasks for the manufacturer and the approved body resulting on the combination of different AoC systems shall be laid down by reference to a deposited “control plan” which is part of the ETA and has to be applied for attestation of conformity and the CE marking on the basis of the ETA. A/C System 1: Certification of the conformity of the product by an Approved Certification Body, without audittesting of samples, on the basis of {see CPD - Annex III.2.(i)}: (a) tasks for the manufacturer - Factory Production Control (see 8.2.1.1. and 8.3.4) - further testing of samples taken at the factory by the manufacturer in accordance with a prescribed test plan (see 8.3.6) (b) tasks for the Approved Body - initial type-testing of the product - initial inspection of the factory and of Factory Production Control - continuous surveillance, assessment and approval of Factory Production Control A/C System 3: Declaration of conformity of the product by the manufacturer on the basis of {see CPD – Annex III.2.(ii), Second possibility}: (a) tasks for the manufacturer - factory production control (b) tasks for the Approved Body - initial type-testing of the product (see 8.2.2.1) ETAG 005-1 Page 42
A/C System 4: Declaration of conformity of the product by the manufacturer on the basis of {see CPD – Annex III,2.(ii), Third possibility}: (a) tasks for the manufacturer initial type-testing of the product factory production control (b) task for the Approved Body - none
Responsibilities Tasks for the manufacturer Factory Production Control (FPC) The manufacturer shall exercise permanent internal control of production and shall ensure that the results meet the set quality level. Note: For the products dealt with in this ETA-Guideline a quality level of 5% is suitable. In this respect guidance can be obtained from “Guidance Paper B” – document CONSTRUCT 95/135, Rev. 1) All the elements, requirements and provisions adopted by the maufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system shall ensure that the product is in conformity with the European Technical Approval (ETA). Note: Manufacturers having an FPC system complying with EN ISO 9001/9002 and addressing the requirements of an ETA are recognized as satisfying the FPC requirements of the Directive (see Guidance Paper “B” – document CONSTRUCT 95/135 Rev. 1).
Testing of samples taken at the factory (A/C-system 1) Both large and small companies produce these products and there is a wide variation in the materials used. Therefore a precise test plan can only be set up on a case-by-case basis. In general it is not necessary to conduct tests on complete kits. Indirect methods will normally be sufficient, eg control of raw materials, manufacturing processes and properties of components.
Declaration of Conformity (A/C-systems 3 and 4) When all the criteria of the Conformity Attestation are satisfied the manufacturer shall make a Declaration of Conformity.
Tasks for the manufacturer or the Approved Body Initial type testing Approval tests will have been conducted by the Approval Body or under its responsibility (which may include a proportion conducted by an indicated laboratory or by the manufacturer, witnessed by the Approval Body) in accordance with chapter 5 of this ETA-Guideline.
ETAG 005-1 Page 43
The Approval Body will have assessed the results of these tests in accordance with chapter 6 of this ETA-Guideline, as part of the ETA issuing procedure. These tests shall be used for the purposes of Initial Type Testing. In this respect Approval Bodies shall be able to have open arrangements with relevant approved bodies to avoid duplication, respecting each other's responsibilities. A/C-system 1: this work shall be validated by the Approved Body for Certification of Conformity purposes. A/C-system 3: this work shall be validated by an Approved Laboratory for Declaration of Conformity purposes by the manufacturer. A/C-system 4: this work should be taken over by the manufacturer for Declaration of Conformity purposes. 8.2.3 8.2.3.1 Tasks for the Approved Body (A/C-system 1) Assessment of the Factory Production Control (FPC) system – initial inspection and continuous surveillance. - Assessment of the Factory Production Control system is the responsibility of the Approved Body. All assessments must be carried out on each production unit to demonstrate that the factory production contol is in conformity with the ETA and any subsidiary information. This assessment shall be based on an initial inspection of the factory. Subsequent continuous surveillance of the factory production is necessary to ensure continuing conformity with the ETA. It is recommended that surveillance inspections be conducted at least twice per year. 8.2.3.2 Certification of conformity The Approved Body shall issue Certification of Conformity of the product.
Documentation (all A/C-systems) In order to help the Approved Body make an evaluation of the conformity, the Approval Body, issuing the ETA, shall supply the information detailed below. This information together with the requirements given in the EC Guidance Paper "B" will: A/C-system 1: generally form the basis on which the Factory Production Control (FPC) is assessed by the Approved Body.
A/C-systems 3 and 4:generally form the basis of FPC. This information shall initially be prepared or collected by the Approval Body and shall be agreed with the manufacturer. Guidance on the type of information required is given below: 8.3.1 The ETA (see Section four, chapter 9 of this Guideline). The nature of any additional (confidential) information shall be declared in the ETA.
ETAG 005-1 Page 44
Basic manufacturing process The basic manufacturing process shall be described in sufficient detail to support the proposed FPC methods. Components for kits are normally manufactured using conventional techniques. Any critical process or treatment of the components affecting performance shall be highlighted.
Product and material specifications These may include: - incoming (raw) materials specifications and declarations (including tolerances). - references to European and/or international standards or appropriate specifications - manufacturer’s data sheets (including tolerances). - principle detail drawings - installation procedures
Manufacturer's Technical Dossier (MTD) The provisions of the FPC system and installation procedures, documented as the Manufacturer's Technical Dossier (MTD), shall be assessed, accepted and registered by the Approval Body. The Factory Production Control system, as a minimum, shall address the following: A. Organisation and responsibilities This includes the organisation chart of the technical part of the company
B. Quality plan i) Control of incoming materials ("raw materials" and/or components) ii) iii) iiii) Control of the production process Control of test equipment Control of finished products
This control is for materials received, to be directly used as components or for the manufacturing of components. This is only applicable to those processes, where components are manufactured. This includes calibration charts, etc. This is only applicable to the components manufactured in the plant.
C. Inspection and testing i) General ii) Inspections and test status
iiii) Records
Requirements for facilities, equipment and personnel in the manufacturing plant. Procedures for inspection and acceptance criteria for materials (raw materials and/or components) by setting a quality level. If indirect testing is used, this needs to be addressed. Procedures for the registration of quality control data Procedures for dealing with non-conforming products
D. Control of non-conforming products
E. Complaints ETAG 005-1 Page 45
Registration Traceability
Procedures for dealing with complaints and a complaint registration chart. A linked system of complaints registration and records regarding quality control data, non-conforming products, transport, etc. Procedures.
F. Handling, storage, packaging and delivery of the product G. Training of personnel
Since 'liquid applied roof waterproofing’ is made on site from components of a kit, the manufacturer's installation procedures shall include quality requirements and conditions for proper installation, such as:
H. Application methods and design rules
Procedures according clause 7.1, and if applicable the specific procedure according to the relevant clause in the Complementary Part. Recommended procedures (e.g. completion report). Recommended procedures, frequencies, means and specific maintenance of surface protective finish layers, if any.
J. Testing of final product on site
Test plan The manufacturer and the Approval Body issuing the ETA shall agree an FPC test plan. An agreed FPC test plan is necessary, as current standards relating to quality management systems (Guidance Paper “B”, EN ISO 9001 / 9002, etc) do not ensure that the product specification remains unchanged and they cannot address the technical validity of the type or frequency of checks / tests. The validity of the type and the frequency of checks / tests, conducted during production of the components (kit) and, if applicable, on its “assembled system”, shall be considered. This will include the checks conducted during manufacture on properties that cannot be inspected at a later stage. These will normally comprise: - material properties - compatibility of components Where materials / components are not manufactured and tested by the supplier in accordance with agreed methods, then, where appropriate, they must be subject to suitable checks / tests by the manufacturer before acceptance.
ETAG 005-1 Page 46
Details of the test plan shall be included in the Manufacturer's Technical Dossier.
Prescribed test plan (only A/C-System 1) The manufacturer and the Approval Body, issuing the ETA, shall agree a prescribed test plan. The characteristic to be addressed as described in the mandate is the Reaction to fire. This will be controlled at least twice per year by analysis / measurement of the relevant characteristics for the “assembled system” of the kit.
Modification of the MTD If, subsequent to the issue of an ETA, the manufacturer wishes to modify the contents of the MTD the proposed changes shall be submitted to the Approval Body (A/C-systems 3 and 4), or to the Approved Body (A/C-system 1) who shall consult with the Approval Body, if necessary, before implementation. The proposed changes and their effects on the contents of the ETA shall be assessed by the Approval Body. Additional tests or justifications may be required before approval is granted. Significant changes may lead to the need to amend and re-issue the ETA. Acceptable changes shall be recorded and registered by the Approval Body in an amended MTD.
CE - marking and information The ETA shall indicate the information to accompany the CE-marking, the placement of CEmarking and the accompanying information (eg on the kit and/or components, an attached label, the packaging or on the accompanying commercial documents). According to the CE Guidace Paper “D” on CE-marking, the required information to accompany the symbol “CE” is: - identification number of the notified body (A/C-System 1) - name / address or identifying mark of the manufacturer of the kit (LARWK) - “class / type …..” indication as to clarify the intended use(s) - last two digits of the year in which the marking was affixed - number of the EC Certificate of Conformity (A/C-System 1) - number of the ETA - dangerous substances (see clause 5.3.2 of this ETAG) - class of external fire performance - class of reaction to fire
The CE marking should be accompanied by the information as given in the ETAG-format document, taking into account that: If the ETA provides all the information regarding the performance characteristics and the appropriate conditions for their achievement (e.g. details of the relevant end use applications covered by the mounting and fixing arrangements provided for the purpose of test), then reference to the ETA is sufficient. If the ETA covers more than one type of product, and the type designation provides all the information regarding the performance characteristics and the appropriate conditions for
ETAG 005-1 Page 47
their achievement (e.g. details of the relevant end use applications covered by the mounting and fixing arrangements provided for the purpose of test), then reference to the ETA and the relevant type is sufficient. Only when the above two options do not provide all the necessary information regarding the mandated performance characteristics (table 4.1), then additional information regarding the performance characteristics and the appropriate conditions for their achievement (e.g. details of the relevant end use applications covered by the mounting and fixing arrangements provided for the purpose of test), needs to accompany the CE Marking. Reference to accompanying information should be given in the ETA.
ETAG 005-1 Page 48
SECTION FOUR THE ETA CONTENT
The ETA content shall be in accordance with the Commission Decision 97/571/EC, dated 22 July 1997. In section II.2 "characteristics of products and methods of verification" the ETA shall include the following note:: In addition to the specific clauses relating to dangerous substances contained in this European Technical Approval, there may be other requirements applicable to the products falling within its scope (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the EU Construction Products Directive, these requirements need also to be complied with, when and where they apply. The ETA is issued for the product/kit on the basis of agreed data/information, deposited with {the Approval Body name}, which identifies the product/kit that has been assessed and judged. Changes to the product/production process/kit, which could result in this deposited data/information being incorrect, should be notified to the {the Approval Body name} before the changes are introduced. The {Approval body name} will decide whether or not such changes affect the ETA and consequently the validity of the CE marking on the basis of the ETA and if so whether further assessment/alterations to the ETA, shall be necessary.
The ETA shall contain information and/or references allowing for, where there is a need eg. attestation of Conformity [see Chapter 8 clause 8.2.3.3 certification, evaluation of conformity Systems 1 & 2], market surveillance, complaints or accidents [all Systems of A/C]), to determine that the products on the market, or intended to be put on the market are in compliance with the approved product as described in the ETA. When such information/references are of a confidential nature it/they shall exist on the ETA file managed by the Approval body and as necessary on the relevant file of any notified body involved. This information/references shall also be of assistance in any renewal of the ETA. The type, scale, range of information will be based on the identification clauses in Chapter 5 of the ETAG.

PREPARATION OF FREE SAMPLES
SCOPE This Annex gives guidance on the procedure for the preparation of free samples of (an) assembled system(s) of roof waterproofing kits (LARWKS).
INTRODUCTION To perform specific tests and/or verifications (eg. the effects of ageing media on different characteristics of liquid applied waterproofing membranes) it is necessary to prepare free film samples of systems. The method of free film sample preparation may differ with the system under examination and the advice of the manufacturer should be sought on the most appropriate method to be used with the materials.
III.3 III.3.1
APPARATUS Base: a rigid support (eg of plywood, glass, plastic coated chipboard or MDF etc.) of sufficient size to provide an even and stable substrate on which to prepare the sample(s) Release agent: to avoid adhesion to the base and to allow subsequent removal of the sample. Examples of release agents known to work are siliconised paper, spray furniture polish, spray silicone release agent, micro-crystalline parafin wax, etc. Thickness control: a means of ensuring a constant and controllable thickness of the free film. Examples: wet film gauges, film spreaders, film casters, bar coaters, steel frames, etc. Spirit level: to allow the base plate to be adjusted to a horizontal position.
III.4 III.4.1
FREE SAMPLE Composition The free sample is the roof waterproofing kit (LARWK), applied in accordance with the manufacturer’s instructions to the appropriate ratio of constituent parts, or to the specified composition by the Approval Body. Number and size of free samples The number and size of free samples will be declared by the Approval Body, dependent on the relevant method of verification.

III.5 PROCEDURE The base shall be placed on a firm support ensuring that it is horizontal. The release agent shall be applied and, where necessary, allowed to dry. Where sheet release agents are used, these shall be firmly fixed to the base without creases or wrinkles. Apply the roof waterproofing kit (LARWK) in the appropriate number of coats, including reinforcement, where appropriate, in accordance with the manufacturer’s instructions (by spraying, spreading or brushing) to the prepared base. For two-coat brush-applied roof waterproofing kits the manufacturer’s instructions for the direction of brushing shall be followed. The mean thickness of the applied membrane shall be controlled in the appropriate manner. The sample shall be allowed to fully cure before removal, without straining, from the base. Any area of free film falling outside the manufacturer’s thickness specification shall be rejected.

Annex IV Reaction to fire – test procedures
The test methods depend on the classification which the product shall meet. Tests according to EN ISO 11925-2 shall be carried out on substrates according to EN 13238. When the liquid applied roof waterproofing kit is intended to be used in combination with other substrates, it shall be tested in end-use practice. Liquid applied waterproofing kit shall be tested in its highest intended thickness. The result is valid for lower thickness. Tests according EN 13823 shall be carried out on substrates according to EN 13238. If the liquid applied waterproofing kit is intended to be used in combination with other substrates it shall be tested as in end-use practice. The liquid applied roof water proofing kit shall be tested in its highest and lowest thickness intended to be used. The test specimen shall be installed on the sample carrier according to figure 1. As a result the tests for the classification to Euroclasses B, C, D and E according to EN 13501-1 refer to the specified substrates and their characteristics. This may cause different Euroclasses for the liquid applied roof waterproofing as an assembled system for different substrates.
