General purpose adhesives for structural assembly - Requirements and test methods
This European Standard specifies requirements for adhesives intended for use in the creation and general assembly of load-bearing, structural elements used in civil engineering works and the construction of buildings. Other than the exceptions stated, it embraces all combinations of bonded materials, used to create or repair load-bearing elements.
It covers individual adhesives and special purpose kits comprising various combinations of adhesive types and components.
It includes test methods and methods of assessment.
The performance requirements in this standard may not be applicable to highly specialised applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialised circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading where specific performance requirements will apply.
The intended use is for internal and external construction elements and those cladding and covering elements (excluding ceramic tiles) specifically required, by regulatory authorities, to provide protection from fire in identified building zones, including escape routes.
This European Standard does not cover:
- Prefabricated, bonded structural components;
- Concrete bonded either to itself or steel or a material based on carbon fibre;
- Wood, when bonded to itself to form a timber based, laminated beam [of the type known as a ‘Glulam’ beam] intended for use as a major structural, load bearing element;
- Thermoplastics [e.g. polyethylene, polypropylene, polyamide and fluorinated polymers in general] unless they have been specifically prepared [usually through a specialised oxidative process] for bonded assembly on site;
- Co-axial metallic assemblies comprising fasteners- threaded and otherwise, pipes and tubes;
- Glass assemblies in structural glazing applications made using silicone adhesives;
- Those structural elements that are permanently immersed in water.

EN 15274:2015 (E) 6 4 Performance characteristics for intended uses 4.1 General The manufacturer shall undertake initial performance tests on the product in accordance with Table 1. The measurement temperature is (23 ± 2) ºC. For measurements obtained at other temperatures, record the temperature with the value. Table 1 — Performance characteristics for intended uses No Characteristics Units Reference Test Method Additional information and test methods a 1 Bond shear strength MPa EN 1465 Explain the used adherend material, surface treatment and thickness of adhesive layer in the technical documentation of the product, because this has an influence to the measured value. 2 Tensile strength b MPa EN ISO 527-2 EN ISO 527-3 For very brittle adhesives it may be more suitable to perform flexural tests instead of tensile, e.g. the EN ISO 178. This is also depending from available test equipment. Especially for production control the test should be easy to perform and show reliable results. 3 Young’s modulus MPa EN ISO 527-2 EN ISO 527-3 4 Fatigue strength b MPa EN ISO 9664 Shear stress determined at a specific number of fault test cycles. 5 Heat resistance ºC EN ISO 75-3 Determination of temperature of deflection under load.

EN 15336
7 Durability
EN ISO 9142 Durability shall be measured by means of the change of the bond shear strength (according to EN 1465) after an ageing test according to EN ISO 9142 conditions. Manufacturer shall declare the relevant ageing conditions for the specific application. 8 Release of dangerous substances 3 EN 13999 (all parts)
9 Impact resistance b N/mm EN ISO 11339
10 Pot life (working life) Minutes EN 14022 Only suitable for two component products. a Instead of the reference test method other test methods may be more suitable, depending from the type of adhesive e.g. Therefore additional test methods are possible for factory production control provided that the producer demonstrates sufficient correlation. b The determination of these additional performance characteristics is only partly needed for specific applications by demand of the user or operator and when subject to regulations. WARNING — The characteristics of the bonded joint may be adversely affected by fire and therefore appropriate protection measures will need to be taken where fire is anticipated. SIST EN 15274:2015
EN 15274:2015 (E) 7 4.2 Sampling General requirements for sampling procedures are set out in EN ISO 15605 and EN 1067. 5 Requirements 5.1 Production control requirements The manufacturer shall undertake selected representative initial identification tests for the product or system as specified in Table 2. These tests shall be used to confirm the composition of the product. The manufacturer shall undertake these tests every 10 tons or every batch, whatever is reached first, and hold the test records (batch is a usual production unit). Table 2 — Production control requirements No Characteristics Reference Test Method Requirement/Tolerance additional information and test methods a 1 Appearance Texture and odour Sensory check Serious errors will be detected by a careful visual judgment of the material. The visual check judges the colour and the colour characteristics (clear / cloudy) as well as the surface structure (fineness of grind, gloss) of the material. If the material has to fulfil not only functional requirements but esthetic ones as well, the visual aspect of the material and/or application becomes increasingly important. In this case, the material has to be compared to references. References can be colour charts, customer or standard laboratory samples. If there is any doubt, following measurements have to be made. 2 Epoxy equivalent EN 1877-1 Determination of epoxy equivalent (only suitable for two component epoxy) 3 Amine functions EN 1877-2 Determination of amine functions using the total basicity number (only suitable for two component epoxy) 4 Isocyanate content for adhesives not containing blocked isocyanate group EN 1242 Determination of isocyanate content 5 Isocyanate content for adhesives containing blocked isocyante group EN ISO 14896 or EN ISO 11909 Determination of isocyanate content a a Instead of the reference test method other test methods may be more suitable, depending for example from the type of adhesive. Therefore additional test methods are possible for factory production control provided that the producer demonstrates sufficient correlation. 5.2 Performance requirements The manufacturer shall undertake performance tests on the product in accordance with Table 3, yearly or every 500 tons, whatever is reached first. The manufacturer shall hold the test records. SIST EN 15274:2015

Therefore additional test methods are possible for factory production control provided that the producer demonstrates sufficient correlation. 5.3 Sampling General requirements for sampling procedures are set out in EN ISO 15605 and EN 1067. 6 Assessment and verification of constancy of performance (AVCP) 6.1 General The compliance of general purpose adhesives with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — determination of the product type; — factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s). 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. — For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for that same characteristics for all products within that same family. NOTE Products may be grouped in different families for different characteristics. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. SIST EN 15274:2015
EN 15274:2015 (E) 9 In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: — at the beginning of the production of a new or modified general purpose adhesive (unless a member of the same product range), or — at the beginning of a new or modified method of production (where this may affect the stated characteristics); or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the general purpose adhesive design, in the raw material or in the supplier of the components, or in the method of production (subject to the definition of a family), which would affect significantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the DoP, although this does not replace the responsibility on the general purpose adhesives manufacturer to ensure that the general purpose adhesive as a whole is correctly manufactured and its component products have the declared performance values. 6.2.2 Test samples, testing and compliance criteria The number of samples of general purpose adhesive to be tested/assessed shall be in accordance with Table 4. Table 4 — Number of samples to be tested and compliance criteria Characteristic Requirement Assessment method No. of samples Compliance criteria Bond shear strength Clause 4, 5.2 EN 1465 1 Clause 4, 5.2 Tensile strength Clause 4 EN ISO 527-2 EN ISO 527-3 1 Clause 4 Fatigue strength Clause 4 EN ISO 9664 1 Clause 4 Young’s modulus Clause 4 EN ISO 527-2 EN ISO 527-3 1 Clause 4 Impact resistance (by means of T-peel test) Clause 4 EN ISO 11339 1 Clause 4 Heat resistance Clause 4 EN ISO 75-3 1 Clause 4 Creep Clause 4 EN 15336 1 Clause 4 Release of dangerous substances Clause 4 EN 13999 (all parts) 1 Clause 4 Durability Clause 4 EN ISO 9142 1 Clause 4 Pot life (working life) Clause 4 EN 14022 1 Clause 4 6.2.3 Test reports The results of the determination of the product type shall be documented in test reports. All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of the general purpose adhesive to which they relate. SIST EN 15274:2015
EN 15274:2015 (E) 10 6.2.4 Shared other party results A manufacturer may use the results of the product type determination obtained by someone else (e.g. by another manufacturer, as a common service to manufacturers, or by a product developer), to justify his own declaration of performance regarding a product that is manufactured according to the same design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same kind, provided that: — the results are known to be valid for products with the same essential characteristics relevant for the product performance; — in addition to any information essential for confirming that the product has such same performances related to specific essential characteristics, the other party who has carried out the determination of the product type concerned or has had it carried out, has expressly accepted1) to transmit to the manufacturer the results and the test report to be used for the latter’s product type determination, as well as information regarding production facilities and the production control process that can be taken into account for FPC; — the manufacturer using other party results accepts to remain responsible for the product having the declared performances and he also: — ensures that the product has the same characteristics relevant for performance as the one that has been subjected to the determination of the product type, and that there are no significant differences with regard to production facilities and the production control process compared to that used for the product that was subjected to the determination of the product type; and — keeps available a copy of the determination of the product type report that also contains the information needed for verifying that the product is manufactured according to the same design and with raw materials, constituents and manufacturing methods of the same kind. 6.2.5 Cascading determination of the product type results For some construction products, there are companies (often called “system houses”) which supply or ensure the supply of, on the basis of an agreement2), some or all of the components (e.g. in case of windows: profiles, gaskets, weather strips)3) to an assembler who then manufactures the finished product (referred to below as the “assembler”) in his factory. Provided that the activities for which such a system house is legally established include manufacturing/assembling of products as the assembled one, the system house may take the responsibility for the determination of the product type regarding one or several essential characteristics of an end product which is subsequently manufactured and/or assembled by other firms in their own factory. When doing so, the system house shall submit an “assembled product” using components manufactured by it or by others, to the determination of the product type and then make the determination of the product type report available to the assemblers, i.e. the actual manufacturer of the product placed on the market. To take into account such a situation, the concept of cascading determination of the product type might be taken into consideration in the technical specification, provided that this concerns characteristics for which either a notified product certification body or a notified test laboratory intervene, as presented below.
1 The formulation of such an agreement can be done by licence, contract, or any other type of written consent. 2 This can be, for instance, a contract, license or whatever kind of written agreement, which should also contain clear provisions with regard to responsibility and liability of the component producer (system house, on the one hand, and the assembler of the finished product, on the other hand. 3 These companies may produce components but they are not required to do so. SIST EN 15274:2015
EN 15274:2015 (E) 11 The determination of the product type report that the system house has obtained with regard to tests carried out by a notified body, and which is supplied to the assemblers, may be used for the regulatory marking purposes without the assembler having to involve again a notified body to undertake the determination of the product type of the essential characteristic(s) that were already tested, provided that: — the assembler manufactures a product which uses the same combination of components (components with the same characteristics), and in the same way, as that for which the system house has obtained the determination of the product type report. If this report is based on a combination of components not representing the final product as to be placed on the market, and/or is not assembled in accordance with the system house’s instruction for assembling the components, the assembler needs to submit his finished product to the determination of the product type; — the system house has notified to the manufacturer the instructions for manufacturing/assembling the product and installat

FprEN 15274:2014 (E) 3 Foreword This document (FprEN 15274:2014) has been prepared by Technical Committee CEN/TC 193 “Adhesives”, the secretariat of which is held by AENOR. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 15274:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Construction Products Directive (89/106/EEC). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Note: Due to fact that the Framework Partnership Agreement between the Commission and CEN & CENELEC is not signed yet, there are currently no New Approach Consultants in place for 2014. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met.
This shall not prevent the processing of draft standards nor the offering of harmonized standards to the Commission. In particular, draft standards can be sent to vote without Consultant assessment.
This note will be removed from the Foreword of the finalized publication.

FprEN 15274:2014 (E) 4 1 Scope This European Standard specifies requirements for adhesives intended for use in the creation and general assembly of load-bearing, structural elements used in civil engineering works and the construction of buildings. Other than the exceptions stated, it embraces all combinations of bonded materials, used to create or repair load-bearing elements. It covers individual adhesives and special purpose kits comprising various combinations of adhesive types and components. It includes test methods and methods of assessment. The performance requirements in this standard may not be applicable to highly specialised applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialised circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading where specific performance requirements will apply. The intended use is for internal and external construction elements and those cladding and covering elements (excluding ceramic tiles) specifically required, by regulatory authorities, to provide protection from fire in identified building zones, including escape routes. This European Standard does not cover: — Prefabricated, bonded structural components; — Concrete bonded either to itself or steel or a material based on carbon fibre; — Wood, when bonded to itself to form a timber based, laminated beam [of the type known as a ‘Glulam’ beam] intended for use as a major structural, load bearing element; — Thermoplastics [e.g. polyethylene, polypropylene, polyamide and fluorinated polymers in general] unless they have been specifically prepared [usually through a specialised oxidative process] for bonded assembly on site; — Co-axial metallic assemblies comprising fasteners- threaded and otherwise, pipes and tubes; — Glass assemblies in structural glazing applications made using silicone adhesives; — Those structural elements that are permanently immersed in water. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

FprEN 15274:2014 (E) 6 4 Performance characteristics for intended uses 4.1 General The manufacturer shall undertake initial performance tests on the product in accordance with Table 1. The measurement temperature is (23 ± 2) ºC. For measurements obtained at other temperatures, record the temperature with the value. Table 1 — Performance characteristics for intended uses No Characteristic Units Reference Test Method Additional information and test methods a 1 Bond shear strength MPa EN 1465 Explain the used adherend material, surface treatment and thickness of adhesive layer in the technical documentation of the product, because this has an influence to the measured value. 2 Tensile strength b MPa EN ISO 527-2 EN ISO 527-3 For very brittle adhesives it may be more suitable to perform flexural tests instead of tensile, e.g. the EN ISO 178. This is also depending from available test equipment. Especially for production control the test should be easy to perform and show reliable results. 3 Young’s modulus MPa EN ISO 527-2 EN ISO 527-3 4 Fatigue strength b MPa EN ISO 9664 Shear stress determined at a specific number of fault test cycles. 5 Heat resistance ºC EN ISO 75-3 Determination of temperature of deflection under load. Heat resistance can also be determined by means of the determination of glass transition temperature according to EN ISO 6721-2. 6 Creep b
EN 15336
7 Durability
EN ISO 9142 Durability shall be measured by means of the change of the bond shear strength (according to EN 1465) after an ageing test according to EN ISO 9142 conditions. Manufacturer shall declare the relevant ageing conditions for the specific application. 8 Release of dangerous substances 3 EN 13999 (all parts)

10 Pot life (working life) Minutes EN 14022 Only suitable for two component products. a Instead of the reference test method other test methods may be more suitable, depending from the type of adhesive e.g. Therefore additional test methods are possible for factory production control provided that the producer demonstrates sufficient correlation. b The determination of these additional performance characteristics is only partly needed for specific applications by demand of the user or operator and when subject to regulations. WARNING — The properties of the bonded joint may be adversely affected by fire and therefore appropriate protection measures will need to be taken where fire is anticipated. kSIST FprEN 15274:2014
FprEN 15274:2014 (E) 7 4.2 Sampling General requirements for sampling procedures are set out in EN ISO 15605 and EN 1067. 5 Requirements 5.1 Production control requirements The manufacturer shall undertake selected representative initial identification tests for the product or system as specified in Table 2. These tests shall be used to confirm the composition of the product. The manufacturer shall undertake these tests every 10 tons or every batch, whatever is reached first, and hold the test records (batch is a usual production unit). Table 2 — Production control requirements No Property Reference Test Method Requirement/Tolerance additional information and test methods a 1 Appearance Texture and odour Sensory check Serious errors will be detected by a careful visual judgment of the material. The visual check judges the colour and the colour properties (clear / cloudy) as well as the surface structure (fineness of grind, gloss) of the material. If the material has to fulfil not only functional requirements but esthetic ones as well, the visual aspect of the material and/or application becomes increasingly important. In this case, the material has to be compared to references. References can be colour charts, customer or standard laboratory samples. If there is any doubt, following measurements have to be made. 2 Epoxy equivalent EN 1877-1 Determination of epoxy equivalent (only suitable for two component epoxy) 3 Amine functions EN 1877-2 Determination of amine functions using the total basicity number (only suitable for two component epoxy) 4 Isocyanate content for adhesives not containing blocked isocyanate group EN 1242 Determination of isocyanate content 5 Isocyanate content for adhesives containing blocked isocyante group EN ISO 14896 or EN ISO 11909 Determination of isocyanate content a a Instead of the reference test method other test methods may be more suitable, depending for example from the type of adhesive. Therefore additional test methods are possible for factory production control provided that the producer demonstrates sufficient correlation. 5.2 Performance requirements The manufacturer shall undertake performance tests on the product in accordance with Table 3, yearly or every 500 tons, whatever is reached first. The manufacturer shall hold the test records. kSIST FprEN 15274:2014

Therefore additional test methods are possible for factory production control provided that the producer demonstrates sufficient correlation. 5.3 Sampling General requirements for sampling procedures are set out in EN ISO 15605 and EN 1067. 6 Assessment and verification of constancy of performance (AVCP) 6.1 General The compliance of general purpose adhesives with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — determination of the product type; — factory production control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s). 6.2 Type testing 6.2.1 General All performances related to characteristics included in this standard shall be determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally accepted performance). Assessment previously performed in accordance with the provisions of this standard, may be taken into account provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction and functionality, such that the results are applicable to the product in question. — For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative for that same characteristics for all products within that same family. NOTE
Products may be grouped in different families for different characteristics. Reference to the assessment method standards should be made to allow the selection of a suitable representative sample. kSIST FprEN 15274:2014
FprEN 15274:2014 (E) 9 In addition, the determination of the product type shall be performed for all characteristics included in the standard for which the manufacturer declares the performance: — at the beginning of the production of a new or modified general purpose adhesive (unless a member of the same product range), or — at the beginning of a new or modified method of production (where this may affect the stated properties); or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the general purpose adhesive design, in the raw material or in the supplier of the components, or in the method of production (subject to the definition of a family), which would affect significantly one or more of the characteristics. Where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed. The specifications of these components shall be documented. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the DoP, although this does not replace the responsibility on the general purpose adhesives manufacturer to ensure that the general purpose adhesive as a whole is correctly manufactured and its component products have the declared performance values. 6.2.2 Test samples, testing and compliance criteria The number of samples of general purpose adhesive to be tested/assessed shall be in accordance with Table 4. Table 4 — Number of samples to be tested and compliance criteria Characteristic Requirement Assessment method No. of samples Compliance criteria Bond shear strength 4, 5.2 EN 1465 1 4, 5.2 Tensile strength 4 EN ISO 527-2 EN ISO 527-3 1 4 Fatigue Strength 4 EN ISO 9664 1 4 Young’s modulus 4 EN ISO 527-2 EN ISO 527-3 1 4 Impact resistance (by means of T-peel test) 4 EN ISO 11339 1 4 Heat resistance 4 EN ISO 75-3 1 4 Creep 4 EN 15336 1 4 Release of dangerous substances 4 EN 13999 (all parts) 1 4 Durability 4 EN ISO 9142 1 4 Pot life (working life) 4 EN 14022 1 4 6.2.3 Test reports The results of the determination of the product type shall be documented in test reports. All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of the general purpose adhesive to which they relate. 6.2.4 Shared other party results A manufacturer may use the results of the product type determination obtained by someone else (e.g. by another manufacturer, as a common service to manufacturers, or by a product developer), to justify his own kSIST FprEN 15274:2014
FprEN 15274:2014 (E) 10 declaration of performance regarding a product that is manufactured according to the same design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same kind, provided that: — the results are known to be valid for products with the same essential characteristics relevant for the product performance; — in addition to any information essential for confirming that the product has such same performances related to specific essential characteristics, the other party who has carried out the determination of the product type concerned or has had it carried out, has expressly accepted1) to transmit to the manufacturer the results and the test report to be used for the latter’s product type determination, as well as information regarding production facilities and the production control process that can be taken into account for FPC; — the manufacturer using other party results accepts to remain responsible for the product having the declared performances and he also: — ensures that the product has the same characteristics relevant for performance as the one that has been subjected to the determination of the product type, and that there are no significant differences with regard to production facilities and the production control process compared to that used for the product that was subjected to the determination of the product type; and — keeps available a copy of the determination of the product type report that also contains the information needed for verifying that the product is manufactured according to the same design and with raw materials, constituents and manufacturing methods of the same kind. 6.2.5 Cascading determination of the product type results For some construction products, there are companies (often called “system houses”) which supply or ensure the supply of, on the basis of an agreement2), some or all of the components (e.g. in case of windows: profiles, gaskets, weather strips)3) to an assembler who then manufactures the finished product (referred to below as the “assembler”) in his factory. Provided that the activities for which such a system house is legally established include manufacturing/assembling of products as the assembled one, the system house may take the responsibility for the determination of the product type regarding one or several essential characteristics of an end product which is subsequently manufactured and/or assembled by other firms in their own factory. When doing so, the system house shall submit an “assembled product” using components manufactured by it or by others, to the determination of the product type and then make the determination of the product type report available to the assemblers, i.e. the actual manufacturer of the product placed on the market. To take into account such a situation, the concept of cascading determination of the product type might be taken into consideration in the technical specification, provided that this concerns characteristics for which either a notified product certification body or a notified test laboratory intervene, as presented below. The determination of the product type report that the system house has obtained with regard to tests carried out by a notified body, and which is supplied to the assemblers, may be used for the regulatory marking purposes without the assembler having to involve again a notified body to undertake the determination of the product type of the essential characteristic(s) that were already tested, provided that:
1 The formulation of such an agreement can be done by licence, contract, or any other type of written consent. 2 This can be, for instance, a contract, license or whatever kind of written agreement, which should also contain clear provisions with regard to responsibility and liability of the component producer (system house, on the one hand, and the assembler of the finished product, on the other hand. 3 These companies may produce components but they are not required to do so. kSIST FprEN 15274:2014
FprEN 15274:2014 (E) 11 — the assembler manufactures a product which uses the same combination of components (components with the same characteristics), and in the same way, as that for which the system house has obtained the determination of the product type report. If this report is based on a combination of components not representing the final product as to be placed on the market, and/or is not assembled in accordance with the system house’s instruction for assembling the components, the assembler needs to submit his finished product to the determination of the product type; — the system house has notified to the manufacturer the instructions for manufacturing/assembling the product and installation guidance; — the assembler (manufacturer) assu
