ASTM C40-99

Standard Test Method for Organic Impurities in Fine Aggregates for Concrete

SCOPE
1.1 This test method covers procedures for an approximate determination of the presence of injurious organic impurities in fine aggregates that are to be used in hydraulic cement mortar or concrete.
1.2 Inch-pound units are to be regarded as standard.  
1.3 This standard does not purport to address all of the safety problems, 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.
