ASTM F2703 ISO 17492 TPP Thermal Protection Performance Tester ASTM D4108 Clothing Shoes Fire Protection Test Machine

The TPP Thermal Protection Performance Tester is designed to evaluate the thermal insulation properties of flame-retardant protective clothing fabrics when exposed to both radiant and convective heat sources. This instrument tests the thermal protection performance of various safety equipment including protective clothing, safety shoes, gloves, and helmet outer surfaces.

Complies with multiple international standards including NFPA 1971, ASTM D4018, GB 8965.1-2009, ISO 17492, and others.
