1、Designation: C602 13aStandard Specification forAgricultural Liming Materials1This standard is issued under the fixed designation C602; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parenthes
2、es indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This specification covers agricultural liming materials,such as qui
3、cklime (burnt lime), hydrated lime, limestone,(calcitic and dolomitic), marl, shells, and by-products includ-ing slag, lime kiln dust and other materials.1.2 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.3 This standard does
4、 not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

In some economic cir

11、pecification E11,asshown in Table 2.NOTE 2These classifications apply where the agricultural limestone isobtained by the normal crushing procedure and the product contains thefines of fracture. In some economic circumstances, coarser products areused. The 250-m (No. 60) sieve was selected because re
12、search has shownthat this sieve gives a more accurate representation of the particle sizedistribution of most agricultural limestones presently produced than a fineror coarser sieve. The 2.36-mm (No. 8) sieve is used to control the upperlimit on the amount of coarse limestone particles that may be i
