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 procedures appear in the following order: Plastic Property Testing Section 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      Permeabiity 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.
