ASTM-D5195 › Historical Revision Information
Standard Test Method for Density of Soil and Rock In-Place at Depths Below Surface by Nuclear Methods
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the calculation of the density of soil and rock by the attenuation of gamma radiation, where the gamma source and the gamma detector are placed at the desired depth in a bored hole lined by an access tube.
1.2 The density, in mass per unit volume of the material under test, is calculated by comparing the detected rate of gamma radiation with previously established calibration data (see Annex A1).
1.3 A precision statement has not been developed for this standard at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasign purposes unless correlated to other accepted ASTM standards.
1.4 The values stated in SI units are regarded as the standard. The inch-pound units given in parentheses are for information only and may be approximate.
1.5 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. Specific precautionary statements are given in Section 6, "Hazards."
