1.1 这些测试方法包括生石灰和熟石灰的物理测试，以及ASTM标准中未涵盖的石灰石的物理测试。 2. 注1: 生石灰和熟石灰对水分和二氧化碳有很高的亲和力。在取样、储存和测试过程中，应注意保护熟石灰和生石灰（见实践 C50 ). 1.2 试验方法按以下顺序出现: 塑性测试 石灰腻子的标准稠度 5. 石灰腻子的可塑性 6. 熟石灰的保水性 7. 空气夹带 8. 坚固性测试 熟石灰和水硬性石灰的高压釜膨胀 9 熟石灰爆裂和点蚀 10 应用程序测试 生石灰消化率 11 石灰石粉的干亮度 12 用实验室球磨机测定石灰石的可磨性 方法 13 熟石灰沉降率 14 粒度分析 残渣和筛分分析 15 干燥石灰石、生石灰和熟石灰的筛分分析 16 空气中粉状生石灰和熟石灰的细度 渗透 17 石灰石粉粒径 18 熟石灰、生石灰粉和 喷气筛分石灰石 19 农业石灰材料的湿筛分析 20 密度测量 熟石灰、生石灰粉的表观松密度， 和石灰石 21 熟石灰、生石灰粉的表观填充密度， 和石灰石 22 熟石灰产品的相对密度（比重） 23 1.3 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸的数学转换- 磅单位仅供参考，不被视为标准单位。 1.4 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。 1.5 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 These test methods cover physical testing of quicklime and hydrated lime, and of limestone not otherwise covered in ASTM standards. 2 Note 1: Quicklime and hydrated lime have a high affinity for moisture and carbon dioxide. Caution should be taken to protect both hydrated and quicklime during sampling, storage, and testing (see Practice C50 ). 1.2 The test methods appear in the following order: Plastic Property Testing Standard Consistency of Lime Putty 5 Plasticity of Lime Putty 6 Water Retention of Hydrated Lime 7 Air Entrainment 8 Soundness Testing Autoclave Expansion of Hydrated and Hydraulic Lime 9 Popping and Pitting of Hydrated Lime 10 Application Testing Slaking Rate of Quicklime 11 Dry Brightness of Pulverized Limestone 12 Limestone Grindability Determination by the Laboratory Ball Mill Method 13 Settling Rate of Hydrated Lime 14 Particle Size Analysis Residue and Sieve Analysis 15 Sieve Analysis of Dry Limestone, Quicklime, and Hydrated Lime 16 Fineness of Pulverized Quicklime and Hydrated Lime by Air Permeability 17 Particle Size of Pulverized Limestone 18 Dry Screening of Hydrated Lime, Pulverized Quicklime, and Limestone by Air Jet Sieving 19 Wet Sieve Analysis of Agricultural Liming Materials 20 Density Measurement Apparent Loose Density of Hydrated Lime, Pulverized Quicklime, and Limestone 21 Apparent Packed Density of Hydrated Lime, Pulverized Quicklime, and Limestone 22 Relative Density (Specific Gravity) of Hydrated Lime Products 23 1.3 The values stated in SI units are to be regarded as standard. The values given in brackets are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.4 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. 1.5 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.
