Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results.
It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. X5873 Method D provides more information on compressive strength of rock.
This test method applies only to hammers with an ast, energy not to exceed 0. Work Item s – proposed revisions of this standard.
Reliable results depend on many factors; Practice D provides a means of asgm some of those factors. Note 2 — The quality of the result produced by this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Accordingly, this limitation should be kept in mind when selecting a hammer type.
Earlier recommendations for rock mechanics applications were only for hammers atsm an impact energy of 0.
Historical Version s – view previous versions of standard. Note 1 — Several types of rebound hammers are commercially available to accommodate testing of various sizes and types of rock. Hammers with energies above 0. For a given plunger tip diameter and radius of curvature, the impact energy of the rebound hammer determines its range of applicability.
Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing and sampling. In addition, they are representative of the significant digits that generally should be retained.
ASTM D – 14 Standard Test Method for Determination of Rock Hardness by Rebound Hammer Method
For the same rock or material, rebound numbers obtained from different hammers are not comparable. Care should be taken when testing such rocks and conglomerates as the rebound values will vary between testing a large piece of aggregate versus softer matrix of the conglomerate. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
No other units of measurement are included in this standard.
These applications include, for examples, the prediction of penetration rates for tunnel boring machines, determination of rock quality for construction purposes, grouping of test specimens, and prediction of hydraulic erodibility of rock.

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.
