2、case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This table listsThese tables list the commercial moisture regains and commercial allowan

3、ces commonly used for a numberof textile fibers. Such moisture regain and allowance values are intended primarily for determining the commercial weight of aspecific fiber when the fiber is bought or sold on this basis. These regain and allowance values also are used in calculating the lineardensity

4、of yarn in procedures employing such factors and in the quantitative analysis of fiber blends.2.
