Organization: ASTM
Publication Date: 10 April 2002
Status: inactive
Page Count: 10
ICS Code (Physical properties of soils): 13.080.20
scope:

This test method may be used to determine the water content of soils and the in-place density of soils using a TDR apparatus.

This test method applies to soils that have 30 % or less by weight of their particles retained on the 19.0-mm (¾-in.) sieve.

This test method is suitable for use as a means of acceptance for compacted fill or embankments.

This test method may not be suitable for organic and highly plastic soils.

All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D 6026.

The method used to specify how data are collected, calculated, or recorded in this standard is not directly related to the accuracy to which the data can be applied in design or other uses, or both. How one applies the results obtained using this standard is beyond its scope.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with 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 determine the applicability of regulatory limitations prior to use.
