BS EN ISO 5659-2:2017 specifies a method of measuring smoke production from the exposed surface of specimens of materials or composites. It is applicable to specimens that have an essentially flat surface and do not exceed 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics.It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested and are not to be considered inherent, fundamental properties.The test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc. and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that can be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye.NOTE This test procedure addresses the loss of visibility due to smoke density, which generally is not related to irritancy potency (see Annex E).It is emphasized that smoke production from a material varies according to the irradiance level to which the specimen is exposed. The results yielded from the method specified in this document are based on exposure to the specific irradiance levels of 25 kW/m2 and 50 kW/m2.Cross References:ISO 13943:2008 Ed 2ISO 291:2008 Ed 4ISO 14934-3:2012 ED2 BS 6809:1987ISO 19706:2011 Ed 2EN 45545-2:2013ISO 5725:1986ISO 29904:2013 ED1ISO/TS 3814:2014ISO 5725-2:1994/COR 1:2002ISO/TS 19021IEC 60695-6-31:1999IEC 60695-6-1:2005/AMD1:2010ISO 5660-1:2015 ED3ISO/TR 16312-2:2007 Ed 1All current amendments available at time of purchase are included with the purchase of this document.
