38、reaction to fire, etc. 4 Principle The reaction to fire classification (Euro classes) shall be determined in accordance with EN 13501-1, respecting the test conditions of the ETICS laid down in this standard. In order to evaluate the reaction to fire all kits of the design ETIC system as well as the

39、 individual components shall be considered. Test results may be also valid for the assessment of the reaction to fire of further design ETICS. Rules are given below. NOTE 1 A European reference fire scenario has not been laid down for facades. In some Member States, the classification of ETICS accor

40、ding to EN 135011 might not be sufficient for the use on facades. An additional assessment of ETICS according to national provisions (e.g. on the basis of large scale tests) might be necessary to comply with Member State regulations, until the existing European classification system has been complet

41、ed. NOTE 2 In some Member States the requirements might exist to demonstrate the behaviour of products with respect to continuous glowing combustion in the case of fire. Additional national assessments e.g. on the basis of national procedures to demonstrate this behaviour might be required until a E

42、uropean harmonized procedure will be available. 5 Instructions for mounting and fixing, field of application 5.1 General This clause gives instructions for mounting and fixing for reaction to fire testing of a kit and its single components. This clause includes the field of application of the test r

43、esults of the kits as well as of its single components. BS EN 16724:2015 EN 16724:2015 (E) 7 Base coats shall be grouped according to the binder type into inorganic (cement-calcium hydroxide, alkali silicate, etc.) and organic (silicon resin, synthetic resin, etc.) coats. Finishing coats shall be gr

44、ouped in the same way. For each group of base coats and finishing coats the product with the highest organic content shall be tested in combination with the adhesive having the highest organic content. If there are only differences in the organic content but no difference in the organic component it

45、self, the product with the highest organic content shall be tested. The test results are valid also for adhesives, base coats and finishing coats with equal or lower organic content. If adhesives, base coats or finishing coats include flame retardants, those components with the lowest amount of flam

46、e retardant shall be tested additionally. The key coat and the decorative coat may be neglected if the layer thickness of each coat is less than 200 m and the organic content is less than 5 %. NOTE The layer thickness may be calculated by the coverage. Key coat and decorative coat shall be considere

47、d for testing unless it can be neglected according to the rules mentioned in the paragraph before. The key coat and the decorative coat with the highest PCS-value (according to EN ISO 1716) shall be used for preparing the specimens. 5.2 Testing according to EN ISO 1182 (Non-combustibility test) 5.2.

48、1 General This test method is relevant for the classes A1 and A2. For classes A1 and A2 every substantial component (3.12) shall be tested. Mechanical fixing devices and ancillary materials which are not continuous but discrete components of an ETICS shall not be considered for testing and classific

NOTE Base coats, finishing coats and adhesives in accordance with the provisions of EC decision 96/603/EC (amended by decisions 2000/605/EC and 2003/424/EC) are considered to satisfy the requirements for performance class A1 without the need for testing. 5.2.2 Base coat and finishing coats The reaction to fire behaviour of base coats and finishing coats not falling under EC decision 96/603/EC (amended by decisions 2000/605/EC and 2003/424/EC) shall be tested by using the product with the highest amount of organic c
