Applicable scope:

Used to measure the thermal radiation resistance of single or multiple layers of fabrics in high temperature environments, and can also be used to measure the thermal insulation performance of other fire-resistant and flame-retardant panels. The thermal radiation resistance is an important performance indicator of flame retardant products. Accurately measuring its protective performance has important guiding significance for selecting materials, researching and developing new products, and improving processing technology.

Testing method:

According to the ISO 6942-2002 (EN366) standard, the protective properties of materials can be tested using two testing methods. The first method (Method A) involves subjecting the specimen to a certain amount of thermal radiation, in order to reproduce the harsh conditions the material is subjected to, and to record the appearance changes. The second method (Method B) is to place the calorimeter on the back of the sample, transfer heat from the back of the sample, and record the trend of temperature over time to determine the level of heat radiation transfer.
