Description of ASTM-D2168 2010ASTM D2168 - 10Standard Test Methods for Calibration of Laboratory Mechanical-Rammer Soil CompactorsActive Standard ASTM D2168 | Developed by Subcommittee: D18.03 Book of Standards Volume: 04.08 ASTM D2168Significance and Use Mechanical compactors are commonly used to replace the hand compactors required for Test Methods D698 and D1557 in cases where it is necessary to increase production. The design of mechanical compactors is such that it is necessary to have a calibration process that goes beyond determining the mass and drop of the hammer. Note 1The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria in Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/and the like. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors. 1. Scope 1.1 These practices for the calibration of mechanical soil compactors are for use in checking and adjusting mechanical devices used in laboratory compacting of soil and soil-aggregate in accordance with Test Methods D698 , D1557 , Practice D6026 , and other methods of a similar nature that might specify these practices. Calibration for use with one practice does not qualify the equipment for use with another practice. 1.2 The weight of the mechanical rammer is adjusted as described in 5.4 and 6.5 in order to provide for the mechanical compactor to produce the same result as the manual compactor.
