1.3 This test method is not applicable to unscoured wool or to wool top.

1.4 This test method specifically requires length in inches and mass in metric units, and is not contrary to ASTM policy. The values stated in inch-pound units are to be regarded as the standard. The information in parentheses is for information only.
