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 parentheses 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.
