Standard Test Methods for Calibration of Laboratory Mechanical-Rammer Soil Compactors

2010-12-31 /Historical
Superseeded by:

1.1 These test methods for the calibration of mechanical soil compactors are for use in checking and adjusting mechanical devices used in laboratory compaction of soil in accordance with Test Methods D698, D1557, and other methods of a similar nature which might specify these test methods. Calibration for use with one method does not qualify the equipment for use with another method.

1.2. The mass of the mechanical rammer is adjusted as described in 5.4 and 6.5 in order to provide that the mechanical compactor will produce the same result as the manual compactor.

1.3 Two alternative procedures are provided as follows:

Section Test Method A Calibration based on the compaction of a 5 selected soil sample Test Method B Calibration based on the deformation of a 6 standard lead cylinder

1.4 If a mechanical compactor is calibrated in accordance with the requirements of either Test Method A or Test Method B, it is not necessary for it to meet the requirements of the other test method.

1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 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. >
