Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates
Designation: C136/C136M - 19 Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates1
1. Scope
1.1 This test method covers the determination of the particlesize distribution of fine and coarse aggregates by sieving.
1.2 Some specifications for aggregates which reference thistest method contain grading requirements including bothcoarse and fine fractions. Instructions are included for sieveanalysis of such aggregates.
1.3 Units—The values stated in cither Sl units or inch-pound units are to be regarded separately as standard. Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining valucs from the two systems may result in non-conformance with the standard.
Non lSieve size is idlentified by its starcdarci designation in Speci-fication E11. The altemative designation given in parentheses is forinforimation only and does not mepresent a diflerent starntcard sieve size.Specification ELl cites the following with respect to Sl units vcrsusinch-pound units as sandardl.“ The walues sEated in Sl units shall beconsidered standard for the dimcnsions of the sieve cloth apenings and thewire diarmeers used in the sieve cloth. The values slaed in inich-poundunits shall be considered standard with rcgard to the sicve frames. pans."and covers.
1.4 This standard does nor puarport to address all of thesafety concernas. if any. associcated wirh irs use. It is rhere sponsibility of the user of this siandard to esiablish cappro-pricte safety,healIh, and erivironnievtal practices and deter-erire rhe applicebiliry of regulctory liitationts prior to use.
1.5 This inernactrioal siandard was developed in accor-dance wirh internsationally recognizedd principles ow standard-ization esablished in the Decision on Principles for theDevelopemens of Inrernetional Srandardds,Geides and Recon-sendations issued by the World Trade Orgarization TechunicalBarriers ro Trade (TBTyCowanissee.
