Designation:F230208Standard Performance Specification forLabeling Protective Clothing as Heat and Flame Resistant1This standard is issued under the fixed designation F2302;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.1.Scope1.1 This specification provides minimum requirements forlabeling protective clothing as heat and flame resistant forapplications where the potential for flame contact or high heatexposure exist.1.1.1 This specification includes requirements that defineheat and flame resistance of materials used in protectiveclothing in a manner to limit the contribution of the clothing forcausing injury to the wearer when exposed to high heat orflame.1.1.2 This specification does not provide requirements thatestablish the level of protection provided by the clothing.1.1.3 This specification does not include testing for theevaluation of the entire clothing item.1.2 This specification does not pertain to materials andclothing that are addressed in other standards.See AppendixX1 for a list of standards for heat and flame resistant protectiveclothing.1.3 This specification does not pertain to applications wherethe conditions of potential flame contact or heat exposure are ofan extended duration and/or are of a high intensity.NOTE1Examples include fire fighting applications,exposure to highenergy electrical arcs and exposures in flash fires.1.4 The values stated in SI units or in other units shall beregarded separately as standard.The values stated in eachsystem must be used independently of the other,withoutcombining values in any way.1.5 This standard measures and describes the response ofmaterials,products,or assemblies to heat and flame undercontrolled conditions,but does not by itself incorporate allfactors required for fire hazard or fire risk assessment of thematerials,products,or assemblies under actual fire conditions.1.6 The following precautionary caveat pertains only to thetest methods portion,Section 8,of this specification:Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD4391 Terminology Relating to The Burning Behavior ofTextilesD6413 Test Method for Flame Resistance of Textiles(Ver-tical Test)E171 Practice for Conditioning and Testing Flexible BarrierPackagingF1358 Test Method for Effects of Flame Impingement onMaterials Used in Protective Clothing Not DesignatedPrimarily for Flame ResistanceF1494 Terminology Relating to Protective Clothing2.2 AATCC Standards:3AATCC 132 Colorfastness to DrycleaningAATCC 135 Dimensional Changes in Automatic HomeLaundering of Woven and Knit Fabrics2.3 ISO Standards:ISO 17493 Clothing for protection against heat and flameTest method for convective heat resistance using a hot aircirculating oven43.Terminology3.1 DefinitionsFor definitions of terms used in thisspecification,related to the combustion of textiles,refer to theterminology contained in Terminology D4391.For definitionsof terms used in this test method,related to protective clothing,refer to the terminology contained in Terminology F1494.Fordefinitions of terms used in this test method,related to textileissues,refer to the terminology contained in TerminologyD123.1This specification is under the jurisdiction of ASTM Committee F23 onPersonal Protective Clothing and Equipment and is the direct responsibility ofSubcommittee F23.80 on Flame and Thermal.Current edition approved May 1,2008.Published May 2008.Originallyapproved in 2003.Last previous edition approved in 2003 as F2302-03.DOI:10.1520/F2302-08.2For 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.3Available from American Association of Textile Chemists and Colorists(AATCC),P.O.Box 12215,Research Triangle Park,NC 27709,http:/www.aatcc.org.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2 afterflame,npersistent flaming of a material after theignition source has been removed.3.3 afterflame time,nthe length of time for which amaterial continues to flame after the ignition source has beenremoved.3.4 afterglow,na glow in a material after the removal ofan external ignition source,after the cessation(natural orinduced)of flaming of the material(see also
