Purpose and scope

This test method is intended for determining the dimensional changes of woven or knitted fabrics, made of fibers other than wool, to be expected when the cloth is subjected to laundering procedures commonly used in the commercial laundry and the home.

Four washing test procedures are established, varying in severity from very severe to very mild, and are intended to cover the range of practical washing from commercial procedure to hand washing.

Five drying test procedures are established to cover the range of drying techniques used in the home and commercial laundry.

Three methods for determining the dimensional restorability characteristics are established for those textiles which require restoration by ironing or wearing after laundering.

These tests are not accelerated and must be repeated to evaluate dimensional changes after repeated launderings.
