The material from the in-place dry density test is physically divided into a control fraction and an oversize fraction based on a designated sieve size see Section 3.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

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 accuracy of the test methods may be affected for materials that deform easily or that may undergo volume change in the excavated hole from standing or walking near the hole aastm the test.

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.

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

Test Method A can satm 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 D, D, D, and D Are you sure you want to unsubscribe monitoring?

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. Test Method A can f 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 asym the maximum particle size allowed in the laboratory compaction test refer to Test Methods DDDand D Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. However, conversions are given in f SI system. The soil or other material being tested should have sufficient cohesion or particle attraction to maintain stable sides on a small hole or excavation, and be firm enough to withstand the minor pressures exerted in digging the hole and placing the apparatus over it, without deforming or sloughing.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results. Active view current version of standard.
