1.1 这些试验方法包括从制造商工厂装运之前或之后对各种铁合金进行取样和测试以确定尺寸的程序。 1.2 它们旨在提供代表每个批次的结果，与制造商对同一批次的认证分析具有可比性。 1.3 买方可以使用其希望的任何取样程序，但在此类样品上获得的结果不得作为投诉或拒绝的依据，除非所遵循的程序的精度等同于这些试验方法中规定的精度。 1.4 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4.1 例外情况- 与网格尺寸相对应的国际单位制 表1 将被视为标准。 1.5 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、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 These test methods cover procedures for the sampling and testing of the various ferroalloys for sizing, either before or after shipment from the plants of the manufacturers. 1.2 They are designed to give results representative of each lot that will be comparable with the manufacturer's certified analysis for the same lot. 1.3 The purchaser may use any sampling procedure he desires, but the results obtained on such samples shall not be a basis for complaint or rejection, unless the procedure followed is of an accuracy equivalent to that prescribed in these test methods. 1.4 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. 1.4.1 Exception— The SI units that correspond to mesh sizes in Table 1 are to be regarded as standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
