The material from the in-place dry density test is physically divided into a control fraction and an oversize fraction based astj a designated sieve size see Section 3. 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 the responsibility asm the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. 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 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 during the test. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. Then the material is considered to consist of two fractions, or portions. 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 dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 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 during the test. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

The material asstm tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test.

While the equipment illustrated in these test methods is used for volumes less than 0. However, for larger sized excavations, Test Method D is preferred. It is the responsibility of the user d49114 this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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. It is scientifically undesirable to combine the use of two separate systems within a single standard. In addition they are representative of the significant digits that generally should be retained. 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.
