Designation:F230010Standard Test Method forMeasuring the Performance of Personal Cooling SystemsUsing Physiological Testing1This standard is issued under the fixed designation F2300;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONIndividuals in various occupations are exposed to high heat stress resulting from increasedmetabolism,or the environment,or both.Environmental heat stress can be especially severe whenindividuals are required to wear Personal Protective Equipment(PPE),which impairs or preventsevaporation of sweat from the skin,and thus nullifies the bodys principal means of removingmetabolic heat.Failure to dissipate this heat can dramatically limit work capacity and heat tolerance,thereby increasing the risk of heat-related illness.To reduce this risk,workers are wearing PersonalCooling Systems(PCS)to extend their exposure time to thermal stress.These systems are intendedto limit the effects of external environmental heat and the internally generated metabolic heat on thebody.For this purpose,standards that objectively quantify the effectiveness of PCS are essential.Therefore,tests that measure important physiological variables,such as core temperature,are essentialin evaluating PCS applications and increasing workers health and safety.1.Scope1.1 This test method covers the physiological measurementof internal body core temperature,skin temperature,thermalexposure time,heart rate response,oxygen consumption,andwhole body sweat rate,to assess the effectiveness of PersonalCooling Systems(PCS)in reducing the effects of thermalstress.1.1.1 To increase safety during physiological testing,thisdynamic test requires the use of human participants whoexhibit specific health and physical fitness requirements.1.2 This test incorporates the use of protective clothingensembles(outer garments)used in conjunction with or wornover top of the PCS.This scope is therefore oriented toindustrial rather than athletic applications.1.2.1 The effectiveness of different PCS will be quantifiedwith the same protective clothing ensemble.Therefore,thephysiological values obtained apply only to the coolingsystems,the particular protective outer garment,and thespecific test conditions.1.2.2 When a protective outer garment is not provided,thistest method requires that PCS shall be tested with the standardouter garment defined within this test method.1.2.3 The present standard does not attempt to determineimportant clothing characteristics,such as thermal insulationand evaporative resistance,of the PCS or of the garments wornwith the PCS.Test Methods F1291 and F2370 can be refer-enced for these clothing measurements.1.3 The values stated in this test method shall be SI units.1.4 It is the responsibility of the test laboratory to obtain thenecessary and appropriate approval(s)required by their insti-tution for conducting tests using human participants.1.5 This test method does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this test method to establishappropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2F1291 Test Method for Measuring the Thermal Insulation ofClothing Using a Heated ManikinF1494 Terminology Relating to Protective ClothingF2370 Test Method for Measuring the Evaporative Resis-tance of Clothing Using a Sweating Manikin1This test method is under the jurisdiction ofASTM Committee F23 on PersonalProtective Clothing and Equipment and is the direct responsibility of SubcommitteeF23.60 on Human Factors.Current edition approved June 1,2010.Published July 2010.Originally approvedin 2004.Last previous edition approved in 2005 as F2300-05.DOI:10.1520/F2300-10.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.2 Other Standards:ISO 8996 ErgonomicsDetermination of Metabolic HeatProduction3ISO 9886 ErgonomicsEvaluation of Thermal Strain byPhysiological Measurements3The Commission for Thermal Physiology of the Interna-tional Union of Physiological Sciences(IUPS ThermalCommission)Glossary of Terms for Thermal Physiology4U.S.Food and Drug Administration(FDA)Cleared Steri-lants and High Level Disinfectants with General Claimsfor Processing Reusable Medical and Dental Devices(March 2009)53.Terminology3.1 Definitions:3.1.1 acclimation,nphysiological adaptations occurringwithin an organism,which reduces the strain or enhancesendu
