ASTM D 6571 : 2022

1.1This test method covers the measurement of compression resistance and recovery properties of any type of highloft nonwoven fabric using a simplistic and economical applied static weight loading technique.

1.2This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.3The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.4This test method offers two options for the measurement of compression resistance and recovery properties. Option 1 contains fewer steps and is, therefore, simpler. Option 2 makes more measurements and provides more details about the behavior of a fabric under these test conditions.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
