Description

1.1 This test method provides a measurement of the commercial mass of a shipment of yarn or manufactured staple fiber or tow. This test method applies to ( 1 ) yarn of all fiber types except silk, glass, asbestos, and bast; ( 2 ) tops and slivers of all fiber types except wool, silk, glass, asbestos, and bast; and ( 3 ) manufactured fibers or tow, except glass and other fibers used for special purposes such as flock (Note 1).

Note 1For other test methods for measuring mass of fibrous materials, refer to Practice D2720 .

1.1.1 Sampling in this test method is primarily for use in acceptance testing rather than production control. manufactured fiber producers usually sample for the commercial mass of product on an on-going basis rather than each shipment to a customer.

1.2 Commercial mass has been traditionally based on one of three options depending on the state of the material: ( 1 ) dried, unscoured yarn, staple fiber, tow, and so forth, using commercial moisture regain in the calculations; ( 2 ) dried, scoured yarn, staple fiber, tow, and so forth, using commercial moisture regain values in the calculations; and ( 3 ) dried, scoured yarn, staple fiber, tow, and so forth, using a commercial allowance agreed upon between the purchaser and the supplier in the calculations.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.
