Thermal Protective Performance Tester
ISO 17492 NFPA 1971 ASTM D4108
Introduction:
Thermal protection performance tester is applicable to different requirements of textile and garment, petrochemical, labour safety protection and quality supervision and testing industries and institutions for the protection of thermal protective performance of protective clothing, for the development of fire-retardant protective clothing, quality control during production and the use of the thermal protection letter function of the flame retardant protective clothing provides a scientific and reliable basis. It is used to detect the thermal protection properties of protective clothing, safety shoes, gloves, helmet outer surfaces, etc. The thermal protection properties of the material are tested by the action of a given heat source of heat radiant.
Standard:
NFPA 1971
Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting
ASTM D4108
Standard test method for thermal protective performance of materials for clothing by the open-flame method
GB 8965.1
Protective clothing--Flame-retardant protection--Part 1: Flame-retardant protective clothing
ISO 17492
Clothing for protection against heat and flame -- determination of heat transmission on exposure to both flame and radiant heat
Application:
Used to detect thermal protection of protective clothing, safety shoes, gloves, outer surfaces of helmets, etc.
