ASTM F2731 - 18 - Standard Test Method for Measuring the Transmitted and Stored Energy of Firefighter Protective Clothing Systems

ASTM F2731 - 18

Standard Test Method for Measuring the Transmitted and Stored Energy of Firefighter Protective Clothing Systems

Status : Current   Published : June 2018



1.1 This test method uses one of two procedures to measure: ( 1) heat energy, which can be directly transmitted through the multilayer structure without compressive force, that can result in predicted burn injury, or ( 2) heat energy directly transmitted through the multilayer structure, followed by applying a compressive force, which rapidly releases stored heat energy in the multilayer structure that can result in a predicted burn injury.

1.1.1 This test method is applicable only to protective clothing systems that are suitable for exposure to heat and flames.

1.1.2 Flame resistance of the material system shall be determined prior to testing according to the applicable performance or specification standard, or both, for the material’s end use.

1.2 This test method establishes procedures for moisture preconditioning of firefighter protective clothing material systems.

1.3 The second-degree burn injury prediction used in this standard is based on a limited number of experiments on forearms of human subjects.

1.3.1 The length of exposures needed to generate a second-degree burn injury in this test method exceeds the exposure times found in the limited number of experiments on human forearms.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to English units or other units commonly used for thermal testing.

1.5  This standard is used to measure and describe the properties of materials, products, or assemblies in response to radiant heat under controlled laboratory conditions but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

1.6  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. Specific precautionary information is found in Section 7.

1.7  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.
