The main purpose
It can be used to measure the thermal radiation resistance of single or multilayer fabrics in high temperature environment, and it can also be used to measure the thermal insulation performance of other fire-retardant panels. Anti-heat radiation performance is an important performance index of flame-retardant products. The accurate measurement of its protective performance has important guiding significance for selecting materials, researching and developing new products, and improving processing technology. This instrument fills the domestic gap.
Instrument characteristics
According to the ISO 6942-2002 (EN366) standard, the protection of materials can be tested according to two test methods. The first method (Method A) is that the sample is subjected to a certain amount of thermal radiation. In order to reproduce the harsh conditions of the material, record Changes in appearance. The second method (Method B) is to place a calorimeter on the back of the sample, heat is conducted from the back of the sample, and record the trend of temperature changes over time to determine the level of heat radiation transfer.
