Contact Heat Transmission Tester ISO12127
The Contact Heat Transmission Tester for Protective Materials is designed to evaluate the thermal conduction performance of materials under contact heat conditions. The instrument measures heat transfer through protective fabrics or their components when subjected to a heated cylinder under a specified load. With precise data acquisition, simple operation, and high safety standards, this tester is widely used in protective clothing testing, particularly for fire-resistant and heat-protective garments.
Applications
The tester is suitable for assessing the heat transfer performance of materials, specifically:
(1) Protective clothing for firefighters and emergency personnel
(2) Heat-resistant and fireproof garment components
(3) Industrial protective clothing fabrics
(4) Laboratory and quality control testing of protective textiles
(5) R&D evaluation of new protective material composites
(6) Compliance testing for ISO and EN standards in protective equipment manufacturing
Standards
This instrument conforms to the following international standards:
(1) ISO 12127-2007 – Protective clothing – Protection against heat and fire – Determination of contact heat transmission through protective clothing or its materials
(2) EN 702 – Protective clothing – Protective against heat and fire – Test methods for the determination of heat transmission through protective clothing or materials
