The Protective Clothing Vertical Flame Spread Tester is used to measure the thermal radiation resistance of single or multi-layer fabrics in high temperature environments, and can also be used to measure the thermal insulation properties of other fire-retardant and flame-retardant sheets. Thermal radiation resistance is an important performance index of flame retardant products. Accurate determination of its protective performance has important guiding significance for selecting materials, researching and developing new products, and improving processing technology.
