ASTM F1060-18

Standard Test Method for Evaluation of Conductive and Compressive Heat Resistance (CCHR)

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.

1.3 This test method should be used to measure and describe the properties of materials, products, or assemblies in response to heat under controlled laboratory conditions and should not be used to describe or appraise the thermal hazard or fire risk of materials, products, or assemblies under actual exposure conditions.

1.4 The values as stated in SI units are to be regarded as the standard. The values in parentheses are given for information only.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
