Designation:D3691/D3691M09Standard Performance Specification forWoven,Lace,and Knit Household Curtain and DraperyFabrics1This standard is issued under the fixed designation D3691/D3691M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This performance specification covers the requirementsfor all knit,lace,foam back,stitch-bonded,conventionalweights,and sheer woven fabrics to be used in the manufactureof curtains and draperies.1.2 This performance specification is applicable to all fab-rics except those made of glass.1.3 For those properties where fabric direction is pertinent,these requirements apply to the length and width directions forwoven fabric and to both the wale and course directions forknit fabric.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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to use.2.Referenced Documents2.1 ASTM Standards:2D231 Methods of Testing Tolerances for Knit Goods;Re-placed by D 3887(Withdrawn 1980)3D1336 Test Method for Distortion of Yarn in Woven FabricsD1424 Test Method for Tearing Strength of Fabrics byFalling-Pendulum(Elmendorf-Type)ApparatusD2261 Test Method for Tearing Strength of Fabrics by theTongue(Single Rip)Procedure(Constant-Rate-of-Extension Tensile Testing Machine)D2724 Test Methods for Bonded,Fused,and LaminatedApparel FabricsD5034 Test Method for Breaking Strength and Elongation ofTextile Fabrics(Grab Test)D7023 Terminology Relating to Home Furnishings2.2 AATCC Test Methods48 Colorfastness to Crocking:AATCC Crockmeter Method16 Colorfastness to Light23 Colorfastness to Burnt Gas Fumes61 Colorfastness to Laundering Home and Commercial:Accelerated116 Colorfastness to Crocking:Rotary Vertical CrockmeterMethod124 Appearance of Fabrics After Repeated Home Launder-ing129 Colorfastness to Ozone in the Atmosphere Under HighHumidities132 Colorfastness to Dry Cleaning135 Dimensional Changes in Automatic Home Launderingof Durable Press Woven or Knit Fabric172 Colorfastness to Non-Chlorine Bleach in Home Laun-dering187 Dimensional Changes of Fabrics:Accelerated188 Colorfastness to Sodium Hyperchlorite Bleach in HomeLaunderingEvaluation Procedure 1 Gray Scale for Color ChangeEvaluation Procedure 2 Gray Scale for StainingEvaluation Procedure 9 Visual Assessment of Color Differ-ence of TextilesNOTE1Reference to test methods in this specification give only thepermanent part of the designation of ASTM,AATCC,or other testmethods.The current editions of each test method cited shall prevail.1This performance specification is under the jurisdiction of ASTM CommitteeD13 on Textiles and is the direct responsibility of Subcommittee D13.63 on HomeFurnishings.Current edition approved Sept.1,2009.Published September 2009.Originallyapproved in 1978.Last previous edition approved in 2008 as D3691 02(2008).DOI:10.1520/D3691_D3691M-09.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American Association of Textile Chemists and Colorists(AATCC),P.O.Box 12215,Research Triangle Park,NC 27709,http:/www.aatcc.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.Terminology3.1 Definitions:For definitions of other textile terms used inthis specification,refer to Terminology D7023 and to theTechnical Manual of the American Association of TextileChemists and Colorists.44.Significance and Use4.1 Fabrics intended for this end-use should meet all of therequirements listed in Table 1.4.2 It should be recognized that fabric can be producedutilizing an almost infinite number of construction variables(e.g.,type of fibers,percentage of fibers,yarn twist,yarnnumber,warp and pick count,chemical and mechanical fin-ished).Additionally,fashion and aesthetics dictate that theultimate consumer may find acceptable articles made fromfabrics that do not conform to all of the requirements in Table1.4.2.1 Hence,no single performance specification can possi-bly apply
