1.3 The buyer shall designate the use, as listed in Table 1, and may specify one or more of the type designations in 1.1.

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 and health practices and determine the applicability of regulatory limitations prior to use.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.


This specification covers lime and limestone products that are suitable for chemical and industrial uses such as in waste acid neutralization, agricultural liming, soil stabilization, asphalt, flue gas desulfurization, drinking water softening, waste and wastewater neutralization, and wastewater treatment plant residuals stabilization. The required chemical composition of quicklime, hydrated lime, and limestone for each selected end use are on the bases of the weight sample taken at the place of manufacture. Quicklime should be free of unslakable residues and should be capable of disintegrating in water to form suspensions of finely divided material.
