CZF-5455 Touch Screen Textile Vertical Burning Tester

1、 Applicable scope

The CZF-5455 Touch Screen Controlled Textile Vertical Burner is an upgraded product based on the original equipment technology. It adopts touch screen control, and the test is highly automated. In addition to the automation functions achieved by various buttons and tools, the touch screen control model can store past test data and retrieve it during the test. This device is suitable for various types of fabrics and their products such as safety nets, protective clothing, seat belts, etc., and is ultimately applicable to the test method for the combustion performance of vertical textile bottom edge ignition specified in the GB5455-2014 standard.
