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

However, conversions are given in the SI system. Link to Active This link will always route to the current Active version of the standard.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in.

The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the users objectives; it is common practice to increase or reduce significant digits or reported data to be commensurate with these considerations.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of asfm limitations prior to use. In addition they are representative of the significant digits that generally should be retained.

However, conversions are given in the SI system. Other relevant standards DS 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 D, D, D, and 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.

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. Then the material is considered to consist of two fractions, or portions.

The material from the in-place v weight test is physically divided into a control fraction and an oversize fraction based on a designated sieve size. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in.

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 However, for larger sized excavations, Test Method D is preferred.

Then the material is considered to consist of two fractions, or portions. In addition they are representative of the significant digits that generally should be retained. It is undesirable to combine the use of two separate systems within a single standard. 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 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 asrm to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.
