ASTM International Standard Test Method for Evaluation of Dimensional Stability of Pile Yarn Floor Covering ASTM D7570-17

1.1 This test method covers the determination of dimensional changes in the lengthwise and width-wise direction and distortion likely to occur when pile floor coverings are exposed to various conditions of moisture and heat. This method is applicable to all pile floor coverings including carpet module form. 1.2 This method is applicable to machine made pile yarn floor covering. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversion to SI units that are provided for information only and are not considered standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
