Thermal Protective Performance Tester (TPP) - lab instrument
The Thermal Protective Performance (TPP) Test Device was developed to measure the time elapsed for convective and radiant heat to penetrate through a protective composite fabric system - measuring the resulting damage to human skin.
Standards：
BS EN ISO 6942. EN 366. EN 407. ISO 11612. ASTM F1939. ASTM F2702. NFPA 1971. NFPA 2112. GB 38543. GB/T 38306
Feature：
Industrial personal computer with analysis software is suitable for severe testing conditions.
Automatic calculation for heat transmission factor and radiant heat transfer index.
Sample holder with force applied kit is easy to operate.
Single pump for shutter movement and cooling water loop.
