For Test Methods D and D only, the dry density determined in the laboratory compaction test may be aetm for larger particle sizes in accordance with, and subject to the limitations of Practice D However, for larger sized excavations, Test Method D is preferred.

Do not show this again. It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and zstm the sand.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. In general, the materials tested would asym a maximum particle size of 3 to e4914 in. While the equipment illustrated in these test methods is used for volumes less than 0.

It should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.

Then the material is considered to consist of two fractions, or portions. For construction control, these test methods are often used as the bases for acceptance of material compacted to a specified density or to a percentage of a maximum unit weight determined by a standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.

The material from the in-place unit weight test is physically divided into a control fraction and an oversize fraction based on a designated sieve size. While the equipment illustrated in these test methods is used for volumes astj than 0. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

However, for larger sized excavations, Test Method D is preferred. In addition they are representative of the significant digits that generally should be retained.

It is beyond atm scope of this standard to consider significant digits used in analytical methods for engineering design.

It is undesirable to combine the use of two separate systems within sstm single standard. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in.

In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

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. For Test Methods D and D only, the unit weight determined in the laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size present in the in-place material being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods DDDDand D The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test.

Then asgm material is considered to consist of two fractions, or portions. The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. It should also be firm enough not to deform or slough due to the minor asfm exerted in digging the hole and pouring the sand.

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test. The 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.
