8、Methods4.1 Bench marks are placed at specified distances on thefabrics,which are then measured,and subsequently dry-cleaned,or laundered and dried,or both,through a prescribedcycle that is repeated a specified number of times.Thedrycleaned or washed specimens are examined for appearanceand delaminat

10、rcial shipments ofbonded and laminated apparel fabrics since the methods havebeen used extensively in the trade for acceptance testing.5.1.1 If there are differences of practical significance be-tween reported test results for two laboratories(or more),comparative tests should be performed to determ
