How many types of procedure are there in UL 94 flammability test?
UL94 flammability test grade is the most widely used plastic material flammability performance standard. It is mainly a fire test standard for plastic box foam materials to evaluate the ability of materials to extinguish after being ignited. According to the burning speed, burning time, anti-drip ability and whether the dripping is burning, there are many methods to determine whether the burning of the material is divided into five test methods according to UL94 flammability test. Pls. check below:
1. The 50W flame horizontal combustion UL94 flammability test, HB40, HB75 classification;
2. The 50W flame vertical combustion test V-0, V-1, V-2 classification;
3. 500W flame combustion test 5VA, 5VB classification;
4. Vertical combustion VTM-0, VTM-1, VTM-2 classification of flexible samples of thin film materials;
5. The foam material burns horizontally HF-1, HF-2 and HBF classification.
