设计:C51 07^标题:与石灰和石灰石相关的标准术语（行业使用）^范围: 1、范围 1.1本术语是指与行业使用的石灰和石灰石产品相关的术语。 1.2在适当情况下，以下定义的各种术语应以一个或另一个形容词“高钙”、“镁质”或“白云质”作为前缀（例如:白云质生石灰；高钙水化熟石灰；镁质或白云质石灰石。） 1.3石灰石的成分应以碳酸盐的百分比表示。在石灰行业感兴趣的石灰石中，通常假设材料几乎全部由碳酸盐组成。如果该假设无效，则应确定非碳酸盐材料的百分比，并以存在的碳酸盐材料表示成分。 1.4有关石灰或石灰石产品的具体应用，请参阅适当的ASTM规范。

DESIG: C51 07 ^TITLE: Standard Terminology Relating to Lime and Limestone (as used by the Industry) ^SCOPE: 1. Scope 1.1 This terminology refers to the terms relating to lime and limestone products as used by the industry. 1.2 Where appropriate, the various terms defined below should be prefixed with one or other of the adjectives "high-calcium," "magnesian," or "dolomitic." (Examples: dolomitic quicklime; high-calcium hydraulic hydrated lime; magnesian or dolomitic limestone.) 1.3 The composition of a limestone should be given in terms of a percentage of the carbonates present. In limestone of interest to the lime industry, it is usually assumed that the material consists almost entirely of carbonates. Where this assumption is not valid, the percentage of noncarbonate material should be determined, and the composition expressed in terms of the carbonate material present. 1.4 For specific application of lime or a limestone product, see the appropriate ASTM specification.
