1.1 本规程适用于买方希望获得单一来源生产的石灰石或石灰均匀性信息的情况。本试验方法通常用于工厂制造的主要材料。抽样、测试和结果展示指南( 表1 )给出了。 1.2 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。 1.3 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。 ====意义和用途====== 4.1 本规程旨在以标准化格式呈现一段时间内单一来源的石灰石或石灰的可变性信息。它适用于试验方法中涵盖的所有材料 C25型 , C110 , C1271 和 C1301 ，和规格 C141 .

1.1 This practice is intended for use in instances where the purchaser desires information on the uniformity of limestone or lime produced at a single source. It is intended that this test method normally be used for the predominant material manufactured at a plant. Guidelines for sampling, testing and presentation of results ( Table 1 ) are given. 1.2 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. 1.3 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. ====== Significance And Use ====== 4.1 This practice is designed to present in a standardized format information on the variability of limestone or lime from a single source over a period of time. It can be applied to all materials covered in Test Methods C25 , C110 , C1271 , and C1301 , and Specification C141 .
