ASTM C 1057:2022

1.1 This practice covers a procedure for evaluating the skin contact temperature for heated surfaces. Two complimentary procedures are presented. The first is a purely mathematical approximation that is used during design or for worst case evaluation. The second method describes the thermesthesiometer, an instrument that analogues the human sensory mechanism and is only used on operating systems. Note 1: Both procedures listed herein are intended for use with Guide C1055 . When used in conjunction with that guide, these procedures can determine the burn hazard potential for a heated surface. 1.2 A bibliography of human burn evaluation studies and surface hazard measurement is provided in the References at the end of Guide C1055 . Thermesthesiometer and mathematical modeling references are provided in the References at the end of this practice ( 1- 5 ) . 2 1.3 This practice addresses the skin contact temperature determination for passive heated surfaces only. The analysis procedures contained herein are not applicable to chemical, electrical, or other similar hazards that provide a heat generation source at the location of contact. 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 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.
