UIC564-2 test is connected to regulations relating to fire protection and firefighting measures in passenger carrying railway vehicles or assimilated vehicles used on international services. Under Appendix 11, the specimen is held vertically in a frame and is exposed to a gas flame which is directed on to the surface of the specimen.
UL94 is a flammability standard by the Underwriters Laboratories of the United States of America. The standard determines the material’s tendency to either extinguish or spread the flame once the specimen is ignited. V0 rating means – burning stops within 10 seconds.
ASTM E84 is an American test standard for assessing the surface burning characteristics of building products. The purpose of this test is to observe the flame spread in order to determine the relative burning behaviour of material. Flame spread index is the measurement for the speed at which the flames progresses across the interior surface of a building, while the smoke developed index measures the amount of smoke the product emits as it burns.
