ISO 6942-2002 Fabric Thermal Protection (Radiation) Performance Tester EN 366
Application:
The fabric thermal protection (radiation) performance tester is used to measure the thermal radiation resistance of the single layer or multilayer of the fabric under high temperature environment, and can also be used to determine the thermal insulation performance 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 is of great guiding significance for the selection of materials, research and development of new products, and improvement of processing technology. This instrument fills the domestic gap.
Standard:
ISO 6942-2002,EN 366,GA 10-2014
Instrument Features:
According to the ISO 6942-2002 (EN366) standard, the protection of the material can be tested according to two test methods.
The first method (method A) is that the sample is subjected to a certain amount of heat radiation, and in order to reproduce the harsh conditions of the material, the appearance change is recorded.
The second method (method B) is to place the calorimeter on the back of the sample, the heat is conducted out from the back of the sample, and the trend of temperature change with time is recorded to determine the level of heat radiation transfer.
