1 SCOPE<\/p>\n

This document specifies the laboratory procedure for determining the burning characteristics of plastics and non-metallic materials when vertically or horizontally oriented bar specimens are exposed to a flame ignition source of 50W. These test methods applicable to determining the linear burning rate and the self-extinguishing properties of materials.
\nThis document is applicable to determining the burning characteristics of the solid and cellular materials that have an apparent density of not less than 250 kg\/m3, determined in accordance with GB\/T 6343-2009.
\nThis document includes two test methods. Method A is horizontal burning test, intended to determine the linear burning rate of materials under specified conditions. Method B is vertical burning test, intended to determine the self-extinguishing properties of materials under specified conditions.
\nNote 1: ISO 9772 specifies the test method for determining the burning characteristics of the materials with an apparent density of 250 kg\/m3 or less.
\nISO 9773 specifies the test method for determining the burning characteristics of the materials that deform due to their thinness or are burned up to the holding clamp using Method B of this document.
\nNote 2: Guidance on pre-selection is given in IEC 60695-1-30.<\/p>\n
