Textile Fbrics Flammability Test Chamber

Textile Fbrics Flammability Test Chamber：

Textile UL94 flame chamber refers to the instrument used to test the combustion performance of textiles. It can measure the burning time, burning rate, smoke emission, dust emission and other indicators of textiles in order to evaluate the combustion performance of textiles.

UL94 Flammability Test Principle:

Place the sample on specified grip in vertical or horizontal direction of the UL 94 instrument. The standard sample is placed horizontally or vertically on a specific fixture to ignite under a specified flame for a certain period of time. By measuring the residual flame and residual combustion time, the sample’s UL 94 flammability rating is evaluated. Find more flammability tester here.
