1. Purpose and Scope

1.1 This test method is an accelerated procedure for determination of the dimensional change of fabrics. The procedure uses an apparatus with programmable settings that simulate multiple home or commercial laundering actions as well as wet processing operations. 1.2 This method does not replace dimensional change test methods currently in use.

2.Principle

2.1 Dimensional changes are determined by comparing the distances between length and width direction bench marks before and after a programmed test cycle.
