ISO 5660-4:2008 specifies a method for evaluating materials and products that produce low levels of heat release when exposed to high heat flux (i.e. irradiance levels) typical of fully developed fires. It differs from ISO 5660-1 by prescribing items such as specific specimen size, specimen holder, specimen orientation, volumetric flow rate for O2 analyses and irradiance levels at which testing is conducted. ISO 5660-4:2008 is intended for use on products and materials that contain only small amounts of combustible elements, e.g. test specimens that yield a total heat release of < 15 MJ m-2. The information obtained from the test method in ISO 5660-4:2008 can also be used for fire safety engineering purposes.
