DANSK DS/ISO 5658-2 PDF

This part of ISO 5658 specifies a method of test for measuring the lateral spread of flame along the
surface of a specimen of a product orientated in the vertical position. It provides data suitable for
comparing the performance of essentially flat materials, composites or assemblies, which are used
primarily as the exposed surfaces of walls. Some profiled products (such as pipes) may also be tested
under specified mounting and fixing conditions.
This part of ISO 5658 is applicable to the measurement and description of the properties of materials,
products or assemblies in response to radiative heat in the presence of a pilot flame under controlled
laboratory conditions. It should not be used alone to describe or appraise the fire hazard or fire risk of
materials, products or assemblies under actual fire conditions.
