1.1本试验方法可用于确定100 mm（4 in.）短纤维的纤维长度和长度分布或更少，使用光纤长度测量单元AL-101。它包括测定松散纤维、精梳条、拉伸条、精轧条、精梳条和粗纱的纤维长度参数。 1.2以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关具体的预防说明，请参阅8。 1.

1.1 This test method can be used to determine the fiber length and length distribution of staple fibers of 100 mm (4 in.) or less, using the Fiber Length Measuring Unit AL-101. It includes determination of the fiber length parameters for loose fibers, carded slivers, drawn slivers, finisher slivers, combed slivers, and roving. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety problems, 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. For specific precautionary statements, see 8.1.
