1、Designation:F266807(Reapproved 2011)Standard Practice forDetermining the Physiological Responses of the Wearer toProtective Clothing Ensembles1This standard is issued under the fixed designation F2668;the number immediately following the designation indicates the year oforiginal adoption or,in the c
2、ase 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.INTRODUCTIONProtective clothing ensembles such as firefighter turnout gear,HAZMAT suits,and bomb suits may
3、impose a physiological strain on the wearer.This strain can take the form of heat stress andcardiovascular and respiratory strain,which can result in injury to the wearer.This practice providesinformation on the measurement of the physiological responses of a wearer to a protective clothingensemble.
4、The protocol is designed to allow comparisons of the physiological responses of subjectswearing different protective clothing ensembles of the same type(for example,firefighter turnout gear)and from different types(for example,firefighter ensemble vs.HAZMAT suit).1.Scope1.1 This practice specifies t
5、he test equipment and proce-dures for determining the physiological responses of subjectswearing a protective clothing ensemble.1.2 This practice covers the physiological measurement ofinternal body core temperature,skin temperature,exposuretime,heart rate response,oxygen consumption,and wholebody s
6、weat rate,to assess the physiological responses ofsubjects wearing a protective clothing ensemble.This practicedoes not measure the musculoskeletal strain on the participantimposed by the protective clothing ensemble.1.2.1 To increase safety during physiological testing,thisdynamic test requires the
7、 use of human participants who meetspecific health and physical fitness requirements.1.3 The present standard does not attempt to determineimportant clothing characteristics,such as thermal insulationand evaporative resistance of the protective clothing ensemble.Test Methods F1291 and F2370 can be u
8、sed for these clothingmeasurements.1.4 The values stated in this practice shall be SI units.1.5 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.1.6 This standard does not pu
9、rport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user,and the testing institution,to consultand establish appropriate safety and health practices anddetermine the applicability of regulatory limitations prior touse of this standard.2.Referenced
