            Fire classification standard
            
                    fire classification standard (UL Flame retardant rating)
            
Flammability grade UL94 is the most widely used flammability standard for plastic materials. It is used to evaluate the ability of materials to be extinguished after being ignited. There are many ways to judge whether or not the bead is fired according to the burning speed, burning time, anti dropping ability, and whether the bead is burning.
            
Each material under test gets a lot of value depending on its color or thickness. When selecting a product's material, its UL grade shall meet the requirements for the thickness of the plastic part wall. UL grades should be reported along with thickness values. Only UL grades are reported. No thickness is not enough. The flame retardant grades of plastics are progressively increased from HB, V-2 and V-1 to V-0:
            
1, HB:UL94 standard in the bottom flame retardant grade. For samples of 3 to 13 mm thick, burning rate is less than 40 mm per minute; samples of less than 3 mm thick, burning speed less than 70 mm per minute; or extinguished before 100 mm mark.
            
2, V-2: the sample was subjected to two 10 second combustion tests, and the flame died within 60 seconds. A fire can fall off.
            
3, V-1: the sample was subjected to two 10 second combustion tests, and the flame died within 60 seconds. No fire can fall.
            
4, V-0: the sample was subjected to two 10 second combustion tests, and the flame died within 30 seconds. No fire can fall from e3Jt5vf0d
