1、Designation:D4685/D4685M15(Reapproved 2020)Standard Test Method forPile Fabric Abrasion1This standard is issued under the fixed designation D4685/D4685M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A numb
2、er in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the abra-sion of pile fabrics when the loss of pile tuffs occur,sometimescalled pile retention or
3、pile pull out.It includes two procedures:1.1.1 Procedure AThe“Heavy Duty”procedure describesthe test option for fabrics over 240 g/m2(7 oz/yd2)or fabricswhich should meet heavy duty end-use conditions of wear.1.1.2 Procedure BThe“Light Duty”procedure describesthe test option for fabrics under 240 g/
4、m2(7 oz/yd2)or fabricswhich should meet light duty end-use conditions of wear.1.2 The test method is intended for both regular,riblesswoven corduroy or other woven pile fabric constructions.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The valu
