Designation:F189714Standard Specification forLeg Protection for Chain Saw Users1This standard is issued under the fixed designation F1897;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 specifies minimum requirements forthe design,performance,testing,and certification of protectiveclothing and protective devices designed to provide cut resis-tance protection to the legs of operators of power chain saws.1.2 The objective of this specification is to prescribe fit,function,and performance criteria for protective clothing andprotective devices that,when worn by chain saw operators,areintended to reduce the severity of leg injuries caused by contactwith a running power saw chain.1.3 This standard is not intended to serve as a detailedmanufacturing or purchasing specification,but can be refer-enced in purchase contracts to ensure that minimum perfor-mance requirements are met.1.4 Controlled laboratory tests used to determine compli-ance with the performance requirements of this standard shallnot be deemed as establishing performance levels for allsituations to which chain saw operators may be exposed.1.5 Mandatory requirements are indicated by the use ofshall;recommendations and advisory information is indicatedby use of should.2.Referenced Documents2.1 ASTM Standards:2F1414 Test Method for Measurement of Cut Resistance toChain Saw in Lower Body(Legs)Protective Clothing3.Terminology3.1 Definitions:3.1.1 approve,vto be acceptable to the authority havingjurisdiction.3.1.2 authority having jurisdiction,nthe organization,office,or individual responsible for approving any equipment,installation,or procedure.3.1.2.1 DiscussionThe term authority having jurisdictionis used in this document in a broad manner since jurisdictionsand the responsibilities of approval agencies vary.3.1.3 certification,na system whereby an organizationdetermines that a manufacturer has demonstrated the ability tomake a product that complies with the requirements of thespecification,authorizes the manufacturer to use a label onproductsthatcomplywiththerequirementsofthespecification,and conducts a follow-up to verify the methodsthe manufacturer uses to determine compliance with therequirements of this specification.3.1.4 certification organization,nan independent,third-party organization that determines product compliance with therequirements of the specification with a labeling and listingfollow-up program.3.1.5 chain saw,na portable power-operated tool used forcutting wood that has cutters linked in a chain.3.1.6 chain speed,nthe speed of synchronized movementof linked cutters around a guide bar and sprocket.3.1.7 chainspeed 50(CS50),nfor chain saw protection,the mean chain speed at which cut through occurs.3.1.7.1 DiscussionThis value establishes the relationshipbetween the probability of cutting through the chain saw 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.3.1.8 chain stop,nfor chain saw cut resistance,theresulting action when a material clogs(jams)the drive sprocketor slows the speed sufficiently to prevent advancement of thesaw chain.3.1.9 cut resistance,nin chain saw testing,the ability of amaterial,while in contact with the linked cutters,to resist cutthrough by the cutters of a moving saw chain,independent ofeither jamming or chain stop.3.1.10 cut through,nfor chain saw cut resistance,theaction of a running chain saw after complete breakthrough ofeither protective garment or protective device.1This specification is under the jurisdiction of ASTM Committee F23 onPersonal Protective Clothing and Equipment and is under the direct responsibility ofSubcommittee F23.20 on Physical.Current edition approved Feb.1,2014.Published March 2014.Originallyapproved in 1998.Last previous edition approved in 2008 as F1897-08.DOI:10.1520/F1897-14.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.11 cut-through time,nfor chain saw cut resistance,thetime required for a running saw chain to affect completebreakthrough of a protective garment or protective device.3.1.12 follow-up program,nthe sampling,inspection,tests,or other measures conducted by the certification organi-zation on a periodic basis to determine the continued compli-ance of products that are being made by the manufacturer to therequirements of the stan
