ASTM C602-19

Standard Specification for Agricultural Liming Materials

ABSTRACT
This specification covers agricultural liming materials, such as quicklime (burnt lime), hydrated lime, limestone, (calcitic and dolomitic), marl, shells, and by-products including slag, and other materials. Agricultural liming materials shall be classified in terms of calcium carbonate equivalent. Hydrated lime, quicklime, and agricultural slag shall be classified depending on the particle size. In sieve analysis of agricultural liming materials, the amount of liming material passing the sieves to the nearest whole percentage of the total weight of the dry sample shall be calculated. Air-cooled blast-furnace slag shall be classified the same as agricultural limestone. The following results for agricultural liming materials shall be reported: percentage calcium carbonate equivalent, percentage moisture, percentage calcium and magnesium, and sieve analysis.
SCOPE
1.1 This specification covers agricultural liming materials, such as quicklime (burnt lime), hydrated lime, limestone, (calcitic and dolomitic), marl, shells, and by-products including slag, lime kiln dust and other materials.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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.  
1.4 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.
