product manual

This machine is widely used in the fields of wire and cable, connector, electronics, communication, electric power, mechanical engineering, metallurgy, etc.

This combustion test is designed and manufactured strictly in accordance with the UL1581 standard. It is mainly used to test the fire protection of insulation or coverings. The tester has the advantages of high accuracy, automatic timing, automatic end of the test, horizontal and vertical combustion integration. This testing machine has an exhaust system that can be automatically opened and closed, a large-area observation window, a lighting device, a flame calibration system, a blowtorch automatic positioning system, etc. In addition, the testing machine adopts PLC+touch screen control, the panel is centralized, and the operation is simple and convenient. This instrument complies with the requirements of VW-1, FT-1, FT-2 in the LU1581, ASTMD5025, ASTMD5207 standards
