This Allied Publication defines a method for determination of smoke generation for a material@ under three sets of specified laboratory conditions. The procedure is based on ISO 5659-2:2006 and as such describes an experimental method for measuring smoke production from specimens of the material@ using a single chamber test. This is supplemented to include detailed requirements for specimen preparation for particular types of material@ additional details for test and calibration procedures to enhance repeatability and reproducibility and data presentation@ including an additional (optional) parameter@ VOF4 (see Sect 10.4) that provides a measure of the early smoke generation by the specimen.
