Designation:F141415Standard Test Method forMeasurement of Cut Resistance to Chainsaw in Lower Body(Legs)Protective Clothing1This standard is issued under the fixed designation F1414;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 garmentsand devices worn to protect the lower body(legs)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,it will bedecided if this test method will be used to determine one orboth of the following:(1)chain speed 50(CS50),and(2)success/failure(jamming/chain stop or no cut in less than 1.5 s)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 The following documents,form a part of this specifica-tion to the extent referenced herein:2.2 ASTM Standards:2D123 Terminology Relating to TextilesD1056 Specification for Flexible Cellular MaterialsSponge or Expanded RubberD1776/D1776M Practice for Conditioning and Testing Tex-tilesF1494 Terminology Relating to Protective Clothing2.3 AATCC Test Methods:3AATCC 96 Dimensional Changes in Laundering of Wovenand Knitted Fabrics,except Wool(1988)AATCC 158 Dimensional Changes on Dry Cleaning inPerchloroethylene:Machine Method2.4 Military Standards:4MIL-STD-105 Sampling Procedures and Tables for Inspec-tion by Attributes2.5 Federal Standard:4FS 5100-86 Type II,Cloth,Duck,Nylon,PolyurethaneCoated3.Terminology3.1 Definitions:3.1.1 chain saw,na portable power operated tool used forcutting wood which has cutters linked in a chain.3.1.2 chain speed,nthe speed of synchronized movementof linked cutters around a guide bar and sprocket.3.1.3 chain speed 50(CS50),nfor chainsaw protection,the mean speed at which cut through occurs.3.1.3.1 DiscussionThis value establishes the relationshipbetween the probability of cutting through the protectiveclothing(or foot protective device)and the speed of the sawchain.For lower chain speeds,the probability of cut throughapproaches zero,while for higher chain speeds,the probabilityof cut through approaches one.3.1.4 chain stop,nthe resulting action when a materialclogs(jams)the drive sprocket or slows the speed sufficientlyto prevent advancement of the saw chain.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 1992.Last previous edition approved in 2013 as F1414-13.DOI:10.1520/F1414-15.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.5 cut resistance,nin chainsaw testing,the ability of amaterial,while in contact with the linked cutters,to resist cutthrough of the cutters of a moving saw chain independent ofeither jamming or chain stop.3.1.6 cut-through,nfor chainsaw cut resistance,the actionof a running chainsaw after complete breakthrough of either aprotective garment or protective device.3.1.6.1 DiscussionWhen a cut through is effected,speedof the saw chain must be measured.3.1.7 jamming,nfor chainsaw cut resistance,the cloggingaction manifested by a protective garment or a device that canproduce a chain stop.3.1.8 lower body,nthat part of the human body whichincludes all portions between the waist and feet,not to includethe feet.3.1.9 protective clothing,nan item of clothing that isspecifically designed and constructed for the intend
