ASTM D2167 PDF

More D It is often used as a basis of acceptance for earthen material compacted to a specified density or percentage of a maximum density determined by a test method, such as Test Methods D, D or D This standard is a field procedure requiring mass measurements to the nearest 5 g. As such, water content calculations should only be reported to two significant digits and density to three significant digits. This test method often is used as a basis of acceptance for soils compacted to a specified density or a percentage of maximum density or unit weight, as determined by a standard test method.

Full Description 1. This test method may require special care for use on 1 soils consisting of unbonded granular materials that will not maintain stable sides in a small hole, 2 soils containing appreciable amounts of coarse material in excess of For soils containing appreciable amounts of particles in excess of The values given in parentheses are for information only. This implicitly combines two separate systems of units; that is, the absolute system and the gravitational system. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.

Zululrajas As such, water content calculations should only be reported to two significant digits and density to three significant digits. However, conversions are given in the SI system. In this system the pound lbf represents a unit of force weight. For soils containing appreciable amounts of particles in excess of This e combines two separate systems of units; that is, the absolute system and the gravitational system. This test method may not be suitable for soils containing crushed rock fragments or sharp edge materials, which may puncture the rubber membrane. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard.
