Horizontal and vertical combustion tester

Horizontal and vertical combustion tester

1. Instrument usage:

The UL-94 horizontal and vertical combustion tester is designed to simulate the early stages of ignition in the surrounding environment of electronic and electrical products. It is used to assess the fire hazard through simulation technology and ensure that the surrounding area of the product does not cause combustion spread when caught on fire. The testing equipment is suitable for components, parts, and components of electrical, electronic, and household appliances, such as insulated casings, switch panels, printed circuit boards, and insulation materials of household appliances. This UL94 horizontal and vertical combustion testing instrument is designed to test the flammability of equipment and appliance component materials. Many testing indicators that are applicable for ultimate use, such as flammability, combustion rate, flame spread, combustion intensity, and the flame retardant performance of the product, are detectable. With a high degree of automation and accurate test data, it is the latest testing instrument we have launched for high demand users.

2. Compliance with standards:

1. Horizontal combustion test: UL94HB (ASTM D 635, IEC 60695-11-10, IEC 60707, ISO 1210)
