Organization: ASTM International
Publication Date: 10 December 1998
Status: inactive
Page Count: 6
ICS Code (Earthworks. Excavations. Foundation construction. Underground works): 93.020
scope:

1.1 This test method covers the estimation of in situ modulus of a rock mass at various depths and orientations. Information on time-dependent deformation may also be obtained.

1.2 The values stated in SI units are regarded as standard. The inch-pound units in parentheses are for information only.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
