1.1 本规范涵盖了水硬性水泥物理试验中使用的天平、天平、参考质量和玻璃刻度的最低要求。 1.2 分析参考质量和天平的要求不包括在本规范中，但可在试验方法中找到 C114 . 有意避免使用限制性术语、类别、范围等，以允许对参考质量和质量测定装置有类似要求的其他标准编写机构使用本规范（如需要）。 1.3 这些要求不足以作为购买参考质量或用于在无放大的情况下确定质量的装置的唯一规范。 1.4 以国际单位制为单位的数值应通过以国际单位制为单位的测量或通过适当的转换获得，使用中给出的转换和舍入规则 IEEE/ASTM SI-10 ，以其他单位进行测量。 1.5 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 This specification covers the minimum requirements for scales, balances, reference masses, and glass graduates used in the physical testing of hydraulic cements. 1.2 Requirements for analytical reference masses and balances are not included in this specification, but are to be found in Test Methods C114 . The use of restrictive terminology, classes, ranges, and so forth has been intentionally avoided to allow the use of this specification by other standards-writing bodies with similar requirements for reference masses and devices for determining mass, if desired. 1.3 These requirements are not sufficiently descriptive to be used as the sole specifications for the purchase of reference masses or devices for determining mass without amplification. 1.4 Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI–10 , of measurement made in other units. 1.5 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.
