16、 at the latest by October 2015, and conflicting national standards shall be withdrawn at the latest by January 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying
17、any or all such patent rights. This document supersedes EN 15274:2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. For relationship with EU Regulation see informative Annex ZA, which is an integral part of this docu
18、ment. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, Franc

BS EN 15274:2015EN 15274:2015 (E) 4 1 Scope This European Standard specifies requ
20、irements 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-beari
21、ng 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 specialized applications in extreme
22、 environmental conditions, e.g. cryogenic use, nor do they cover specialized 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 cl
23、adding 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 t
24、o 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 polyme
25、rs in general unless they have been specifically prepared usually through a specialized 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 a
26、dhesives; 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.

BS EN 15274:2015EN 15274:2015 (E) 6 4 Performance characteristics for intended uses 4.1 General The manufacturer
37、shall undertake initial performance tests on the product in accordance with Table 1. The measurement temperature is (23 2) C. For measurements obtained at other temperatures, record the temperature with the value. Table 1 Performance characteristics for intended uses No Characteristics Units Referen

39、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 Youn

Heat resistance can also be determined by means of the determination
41、of glass transition temperature according to EN ISO 6721-2. 6 Creep bEN 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 releva
42、nt ageing conditions for the specific application. 8 Release of dangerous substances g/m3 EN 13999 (all parts) 9 Impact resistance bN/mm EN ISO 11339 10 Pot life (working life) Minutes EN 14022 Only suitable for two component products. aInstead of the reference test method other test methods may be
43、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. bThe determination of these additional performance characteristics is only partly needed for specific
44、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.

45、ling 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
46、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).

47、ment/Tolerance additional information and test methods a1 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 (fine
48、ness 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
49、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 Isocy
