本试验方法用于测定由羊毛以外的纤维制成的机织物和针织物在经过商业洗衣房常用的洗涤程序后的尺寸变化。提供了从严重到轻微的一系列清洗测试程序，以模拟商业洗衣房中发现的清洗类型。建立了五个干燥试验程序，以涵盖所使用的干燥技术。这些试验不会加速，必须重复进行，以评估多次洗涤的尺寸变化。通过测量洗涤前应用于织物的基准距离的变化，确定机织物和针织物试样在洗涤、干燥和恢复过程中的尺寸变化，这是典型的商业洗涤过程。

This test method is used for the determination of dimensional changes of woven and knitted fabrics made of fibers other than wool when subjected to laundering procedures commonly used in a commercial laundry. A range of laundering test procedures from severe to mild is provided to allow simulation of the types of laundering found in commercial laundry. Five drying test procedures are established to cover the drying techniques used.These tests are not accelerated and must be repeated to evaluate dimensional changes for multiple launderings.The dimensional change of woven and knitted fabric specimens subjected to washing, drying and restoration procedures typical of commercial laundering are determined by measuring changes in bench mark distances applied to the fabric before laundering.
