ASTM F3672-23

1.1This test method covers the determination of the evaporative resistance of clothing items that cover only the head (Option 1), a hand (Option 2), or a foot (Option 3). It describes the measurement of the resistance to evaporative heat transfer from a heated sweating thermal manikin form to the testing environment.

1.2The evaporative resistance values obtained apply only to the particular clothing items evaluated and for the specified environmental conditions of each test.

1.3Evaporative resistance values reported in SI units shall be regarded as standard.

1.4This 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.

1.5This 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.
