Product Details of the the UL94 Flame Chamber
The UL94 horizontal vertical burner adopts the full standard satisfaction design concept and considers many test standards and is integrated into one test box. The horizontal vertical burner is designed to test the UL standard flammability performance of equipment and appliance parts materials. Test indicators for end use such as flammability, burning rate, flame spread, burning strength and flame retardancy of the product can be tested.
It conforms to all five UL 94 horizontal and vertical burner tests and associated ASTM international standards. There are:
Horizontal Burning Test; UL 94HB (ASTM D 635, IEC 60695-11-10, IEC 60707, ISO 1210).
Vertical Burning Test: UL 94 V-0, V-1, or V-2 (ASTM D 3801, IEC 60695-11-10, IEC 60707, ISO 1210).
Vertical Burning Test: 5VA or 5VB (ASTM D 5048, IEC 60695-11-20, IEC 60707, ISO 9772).
