Conductive and Compressive Heat Resistance Tester ASTMF1060-2018

Conductive and Compressive Heat Resistance Tester

Product introduction:

1.1 This test method is used to measure the thermal-protective properties of materials that provide thermal insulation when contact is made with hot surfaces during a limited exposure up to 1 min.

1.1.1 During this limited time exposure, the temperature can reach a threshold approaching 600 °F (316 °C).

1.2 Because there is significant potential for injury, the thermal-insulative properties of the materials used in the construction of protective clothing including, but not limited to, woven fabrics, knit fabrics, battings, sheet structures, and any composites, need to demonstrate they are capable of reaching a heat threshold that is sufficient to allow prediction of either a pain sensation or a second-degree burn injury to human tissue.
