Flammability ul 94
WebMaterials with a “B” rating on the UL 94 Vertical test can also be tested in the less severe UL 94 HB (for horizontal burning), which measures simply a flame spread rate. The UL 94 test is the most widely used fire test for plastic materials, especially fire retarded ones, and the results are almost always found in specifications and in data WebUL 94 is a safety standard to determine the flammability of plastic materials. This test is released by Underwriters Laboratories of the United States. It measures: The ability of the plastic part to extinguish or spread the flame after ignition.
