ISO 2017 All rights reserved vBS EN ISO 5659-2:2017ISO 5659-2:2017(E)IntroductionFire is a complex phenomenon; its development and effects depend upon a number of interrelated factors. The behaviour of materials and prod

49、ucts depends upon the characteristics of the fire, the method of use of the materials and the environment in which they are exposed to (see also ISO/TS 3814 and ISO 13943).A test such as is specified in this document deals only with a simple representation of a particular aspect of the potential fire situation, typified by a radiant heat source, and it cannot alone provide any direct guidance on behaviour or safety in fire. A test of this type may, however, be used for comparative purposes or to ensure the existence of a certain quality of perform
