ASTM D4770/D4770M-00(2007)

1.1 This test method covers procedures for determining the tactile appearance and integrity of a highloft nonwoven batting after machine washing or drycleaning when tested in a finished product or a panel assembly simulating the construction of the finished product.

1.2 This test method is not intended for use on wool/wool blend and cotton/cotton blend batting and needle-punched structures.

1.3 This test method provides the values in both SI units and inch-pound units. "Inch-pound units" is the technically correct name for the customary units used in the United States. "SI units" is the technically correct name for the system of metric units known as the International System of Units. The values stated in either system of units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining in any way.

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.
