ASTM D2259-96

1.1 This test method is used to determine the shrinkage of yarns in skein form when immersed in solvent or boiling water or exposed to dry heat, or saturated steam, for specific time periods. All measurements are made when the yarn is at standard conditions. This test method is applicable to yarns made from any fiber or combination of fibers where the tex of the yarn is known or can be determined. This is not recommended for elastomeric yarns and those yarns that stretch more than 5% under the tension loadings prescribed, although it has been used for the latter.

Note 1-Procedures for determining yarn shrinkage and bulk properties of textured yarns are covered in Test Method D 4031.

1.2 This test method shows the values in both inch-pound and SI 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 acceptable metric units or in other units shall be regarded as standard. The values expressed in each system may not be exact equivalents; therefore each system must be used independently of the other without combining in any way.

1.3 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.
