XHF-19NTA Heat Radiation Thermal Protection Tester，This device is use for heat protection test for fabric of single layer or multi-layer under the high temperature. It also can be used to determine the heat-insulating property of other fire retardant board.

Thermal radiation is a important performance indicator of flame retardant products. Accurate determination of its protective properties is very important to select materials, research and development of new products, improved processing techniques.

ISO 6942-2002, EN366

Thermal protection performance tester According to ISO 6942-2002 (EN366) standard, there are two testing method.

Method A: Made the sample absorb a certain amount of heat radiation in order to reproduce the material the inclement conditions, recording changes in appearance.

Method B: Put calorimeter at back of the specimen, heat conduction from samples back, recording temperature trends over time in order to determine the level of heat transfer radiation
