There are currently three main methods used to evaluate the flame retardant protection of flame retardant workwear:

1. Vertical burning test method, test process: Use a standard methane gas flame to continue burning the fabric for 12 seconds and then remove or extinguish it. Observe the continued burning of the fabric and measure the length of fabric damage after burning. The vertical burning test method is to simulate the burning state of the fabric when the flame starts from the bottom of one end of the fabric, which rarely occurs in actual real fires.

2. Thermal protection performance (TPP) test method, the thermal protection performance TPP test method, is closer to the real situation and can better reflect the thermal protection performance of the fabric. Widely adopted by NFPA and national standards.

3. Thermal instrument test method. Thermal instrument test method uses a thermal instrument of a simulated human model for testing. It is a test of actual fire conditions. It is a more realistic simulation and can better reflect the thermal protection performance of flame-retardant clothing. It is one of the most advanced thermal burn assessment equipment in the world.
