ASTM C1580-05

Standard Test Method for Water-Soluble Sulfate in Soil

SIGNIFICANCE AND USE
This test method can be used to determine if soils could have an adverse reaction with hydraulic cement concrete.
SCOPE
1.1 This test method is for the determination of water-soluble sulfate in soils.
1.2 This test method was developed for concentrations of water-soluble sulfate in soils between 0.02 and 3.33 % sulfate by mass.
1.3 This test method does not determine sulfur in any form except as sulfate.
1.4 Some governing bodies regulate the movement of soils from one area to another. It is up to the sampler and laboratory to comply with all regulations.
1.5 The values stated in SI units are to be regarded as the standard.
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 to determine the applicability of regulatory limitations prior to use.
