Designation:F145815Standard Test Method forMeasurement of Cut Resistance to Chainsaw of FootProtective Devices1This standard is issued under the fixed designation F1458;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 test method measures cut resistance of foot protec-tive devices that are designed to protect the foot whenoperating a chainsaw.1.2 This test method may be used to test for compliance tominimum performance requirements in established safety stan-dards.1.2.1 By agreement between the purchaser and the supplier,or as required by established safety standards,this test methodcan be used to determine any one or both of the following:(1)chain speed 50(CS50),(2)success/failure(jamming/chainstop)at specified chain speed.1.3 This test method may be used to determine levels ofprotection for areas of coverage as stipulated in establishedsafety standards.1.4 The values stated in SI units are to be regarded asstandard.NOTE1The values stated in each system may not be exact equiva-lents;therefore,each system must be used independently of the other,without combining values in any way.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2F1414 Test Method for Measurement of Cut Resistance toChainsaw in Lower Body(Legs)Protective ClothingF1494 Terminology Relating to Protective Clothing2.2 AATCC Test Methods:3AATCC 96 Dimensional Changes in Laundering of Wovenand Knitted Fabrics,Except Wool(1988)AATCC 158 Dimensional Changes on Drycleaning in Per-chloroethylene:Machine Method2.3 Military Standards:4MIL-STD-105 Sampling Procedure and Tables for Inspec-tion by AttributesMIL-C-12369 Cloth,Ballistic,Nylon2.4 Federal Standard:5FS 5100-86 Type II,Cloth,Duck,Nylon,PolyurethaneCoated3.Terminology3.1 Definitions:3.1.1 centerline,nin foot protective devices,a line thatextends from the toe of the footwear horizontally along the soleto the heel vertically to the top of the footwear,and diagonallyto the point of intersection at the toe.3.1.2 chainsaw,na portable power-operated tool that hascutters linked in a chain used for cutting wood.3.1.3 chain speed,nthe speed of synchronized movementof linked cutters around a bar and sprocket.3.1.4 chain speed 50(CS50),nfor chainsaw protection,the mean speed at which cut through occurs.3.1.4.1 DiscussionThis value establishes the relationshipbetween the probability of cutting through the chainsaw legprotective clothing(or foot protective device)and the speed ofthe saw chain.For lower chain speeds,the probability of cutthrough approaches zero,while for higher chain speeds,theprobability of cut through approaches one.3.1.5 chain stop,nfor chainsaw cut resistance,the result-ing action when a material clogs(jams)the drive sprocket orslows the speed sufficiently to prevent advancement of the sawchain.1This test method is under the jurisdiction ofASTM Committee F23 on PersonalProtective Clothing and Equipment and is the direct responsibility of SubcommitteeF23.20 on Physical.Current edition approved Nov.1,2015.Published January 2016.Originallyapproved in 1998.Last previous edition approved in 2008 as F1458-04(2008).DOI:10.1520/F1458-15.2For 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 27709-2215,http:/www.aatcc.org.4Available from DLA Document Services,Building 4/D,700 Robbins Ave.,Philadelphia,PA 19111-5094,http:/quicksearch.dla.mil.5Available from U.S.Government Publishing Office,732 North Capitol Street,NW,Washington,DC 20401-0001,http:/www.gpo.gov.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.6 cut resistance,nthe ability of a material,while incontact with the linked cutters,to resist cut through of thecutters of a moving saw chain,independent of either jammingor chain stop.3.1.7 foot,nthe terminal part of the vertebrate leg,includ-ing the ankle,upon which an individual stands.3.1.8 foot protective device,nfor chainsaw cut resistance,an article of personal equipment which covers the foot andankle for the purpose of providing limited protection frominjury due to contact with a moving saw chain.3.1.9 footwear,na boot or shoe of any construction.3.1.10 gaiter,nfor chainsaw cut resistance,a foot protec-tive de
