LFY-607 Radiation Heat Conduction Tester

Main application
It is used to measure the heat radiation protection performance of single or multiple layers of fabrics in high-temperature environments, and can also be used to test the heat insulation performance of other fireproof and flame-retardant materials. Heat radiation protection performance is an important performance indicator of fireproof products. Accurate measurement of its protective performance has significant guiding significance for material selection, research and development of new products, and improvement of processing techniques. This instrument fills the domestic gap.
Instrument features
According to the ISO 6942-2002 (EN366) standard, the protective performance of materials can be tested by two testing methods. The first method (Method A) is that the sample is exposed to a certain amount of heat radiation. To reproduce the harsh conditions of the material, changes in appearance are recorded. The second method (Method B) is to place the calorimeter on the back of the sample, and the heat conducts from the back of the sample, and the trend of temperature changes over time is recorded to determine the level of heat radiation transfer.
