ASTM F2668-16R22 - Standard Practice for Determining the Physiological Responses of the Wearer to Protective Clothing Ensembles

1.1 This practice specifies the test equipment and procedures for determining the physiological responses of subjects wearing a protective clothing ensemble.

1.2 This practice covers the physiological measurement of internal body core temperature, skin temperature, exposure time, heart rate response, oxygen consumption, and whole body sweat rate to assess the physiological responses of subjects wearing a protective clothing ensemble. This practice does not measure the musculoskeletal strain on the participant imposed by the protective clothing ensemble.

1.3 The present standard does not attempt to determine important clothing characteristics, such as thermal insulation and evaporative resistance of the protective clothing ensemble. Test Methods F1291 and F2370 can be used for these clothing measurements.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 It is the responsibility of the test laboratory to obtain the necessary and appropriate approval(s) required by their institution for conducting tests using human participants.

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.

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.
