Scope

This standard specifies the laboratory test method for the horizontal or vertical combustion performance of plastic and non-metallic material samples under the condition of 50W flame. This standard specifies the determination of the linear burning rate and afterflame/afterglow time and the burning length of the specimen. This standard is applicable to solid and foam materials whose apparent density is not less than 250kg/m³ as determined in accordance with GB/T 6343. The material should use ISO 9773. This standard specifies the combustion performance class (see 8.4 and 9.4), which can be used for quality assurance or pre-selection of product constituent materials. Reliable results are obtained when the specimen thickness is equal to the minimum thickness at which the material is applied.
