Testing is performed on the product in both an “asreceived” condition and after ten laundering or dry cleaningcycles usin
35、g standardized procedures. Users of this specifica-tion are also permitted to use laundering or dry cleaningprocedures for conditioning samples as specified in the manu-facturers care instructions for a minimum of ten cycles.4.2 This specification is not intended to replace standardsthat have alread
36、y been developed for specific types of flameand heat resistant protective clothing, including clothing forprotection from flash fire, clothing for protection againstF2302032electric arc, and protective clothing for various fire fighting andemergency response applications. SeeAppendix X1 for a list o
37、fspecifications for specific types of heat and flame resistantprotective clothing.4.3 This specification does not address all areas of protec-tive clothing performance for heat and flame exposure. Forexample, the specification does not address insulation providedby these garments. Rather this specif
38、ication is designed toprovide an assessment of the potential of the clothing itself tobecome a hazard to the wearer if exposed to flame and highheat.4.4 This specification does not provide an overall evaluationof the clothings flame or heat resistance. Instead, heat andflame resistance tests of the
39、primary materials used in theconstruction of the clothing are used to assess clothing heat andflame resistance. This specification permits excluding testingof clothing components that are not in direct contact with thebody during normal wearing. Therefore, it is important thatusers of this specifica
40、tion recognize that certain components,based on their composition, size, and location could contributeto burn injury in the event of a high heat or flame exposure.5. Requirements5.1 Test the materials used in the construction of protectiveclothing items for heat and flame resistance as specified inS
41、ection 8. Elastic, hook and loop fastener, closures, labels,emblems, patches and other clothing components, when not incontact with the wearers body in the normal wearing of thegarment, shall be permitted to be excluded from testing. Alltested materials shall meet the minimum criteria provided inTab
42、le 1.NOTE 2While this specification permits excluding elastic, hook andloop fastener, closures, labels, emblems, patches, and other clothingcomponents from testing, users of the specification are cautioned thatthese components could contribute to burn injury depending on theircomposition, size, and
43、location on the protective clothing item beinglabeled.6.
