GB5455 Textile Vertical Combustion Tester (Vertical Flame Retardant Performance Tester)

GB5455 Textile Vertical Combustion Tester (Vertical Flame Retardant Performance Tester)

1、 Scope of use

The GB5455 touch screen controlled textile vertical combustion instrument developed and produced by Beijing Xinsheng Zhuorui Technology Co., Ltd. and Xunyu Technology Co., Ltd. is an upgraded product based on the original equipment technology. It adopts touch screen control and has a high degree of automation in testing. 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 testing. This device is suitable for various fabrics and their products such as safety nets, protective clothing, and seat belts, and is ultimately applicable to the test method for the combustion performance of vertical textile bottom edges when ignited as specified in the GB5455-2014 standard.
