This standard specifies a method for determining the flammability behavior of thin flexible vertical plastic specimens when exposed to small flame ignition sources. It details procedures for preparing and conditioning test samples, conducting the burning tests, and evaluating results according to specific criteria. The method is designed to assess the propensity of plastic materials to propagate flames under specified conditions and can be used by manufacturers, testing laboratories, and regulatory bodies involved in material safety assessments.
