Introduction:   

The TPP thermal protection performance tester is used to test the thermal protection performance of protective clothing, safety shoes, gloves, helmets, etc., by detecting the thermal protection performance of materials under the action of a predetermined thermal radiation heat source. 
The TPP thermal protection performance tester can comply with NFPA 1971, ASTM D4018, GB 8965.1-2009, ISO 17492 test standards.

• NFPA 1971:Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting
• ASTM D4108:for Thermal Protective Performance of Materials for Clothing by Open-Flame Method
• ISO 17492: Specifies a test method for measuring the heat transfer of horizontally mounted flame-resistant textile materials when exposed to a combination of convective and radiant energy.
