2、icates 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 quicklime(burn
3、t 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 not purport to add
4、ress 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.Referenced Documents2.1 ASTM Standards:2C25 Test Methods

9、 classified in termsof calcium carbonate equivalent(C.C.E.),as shown in Table 1.NOTE1Marl and some by-product liming materials are used forneutralizing soil acidity,but due to their varying composition,theirchemical limits are not included.In some economic circumstanceslimestone,lime kiln dust,slag,
10、and shells of less than 80%C.C.E.may beused.5.Sieve Analysis Classifications for AgriculturalLimestone5.1 Agricultural limestone shall be classified according tothe minimum percentages passing the 2.36-mm(No.8)and250-m(No.60)sieves conforming to Specification E11,asshown in Table 2.NOTE2These classi
11、fications 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 research has shownthat this sieve gives a more accurate repres
12、entation 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 in theproduct.6.Sieve Analysis Classifications for Agricultural S
