EN 13238：Reaction to Fire Tests for Building Products - Conditioning Procedures and General Rules for Selection of Substrates
Abstract摘要
The Construction Products Directive requires products to be tested in their end use condition which, for the purpose of substrates, could lead to an economically unrealistic large variety of tests to be carried out. This large spectrum has been reduced to a practical number of standard substrates that enables the majority of end use conditions to be represented. Rules for the selection of such substrates are also given in this standard.
BS EN 13238 is for use in conjunction with European Standards covering the reaction to fire test methods for the relevant construction products.
BS EN 13238 describes the conditioning procedures for test specimens which will be tested according to the European standards for reaction to fire.
BS EN 13238 also covers the rules for the selection of substrates for construction products when carrying out reaction to fire tests.
BS EN 13238 does not contain requirements for:
· The pre-drying of test specimens for the non-combustibility test according EN ISO 1182
· Methods of cleaning (e.g. washing) and other methods for the assessment of durability aspects, which are dealt with in the relevant product standards.
