Standard Test Method of Sampling and Testing Staple Length of Grease Wool
 N D1234

Annotation

This test method2 covers procedures for sampling and measuring the unstretched staple length, and variability in length, of grease or pulled wool staples. The test method is also applicable to mohair and other animal fibers in staple form. The procedure is not recommended for individual fibers or groups of straightened fibers.

NOTE 1—The determination of fiber length in wool top is covered in Test Method D519, the determination of fiber length of wool is covered in Test Method D1575.

The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This standard does not purport to address 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.

2 Further information covering the procedures and techniques described in this test method appears in D. D. Johnston, H. Dean Ray, W. J. Manning, and E. M. Pohle, "Relationships of Staple Length in Grease Wool and Resultant Top," Textile Research Journal, Vol 21, October 1951, pp. 757–762.
