1.1 This test method covers the determination of the linear density of "as produced" elastomeric yarns made from rubber, spandex or other elastomers using a skein.

Note 1 - For the determination of linear density of elastomeric yarns using short length specimens, refer to Test Method D2591.

1.2 The method is not applicable to covered, wrapped, or core-spun yarns, or yarns spun from elastomeric staple, or elastomeric yarns removed from fabrics.

1.3 This test method is applicable to elastomeric yarns having a range of 40 to 3200 dtex (36 to 2900 denier).

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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.
