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. 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.

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 dry density determined in the laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D Historical Version s – view previous versions of standard. While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. It is not possible to buy in the shop – please contact us.

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 This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

Then the material is considered to consist of two fractions, or portions. 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 The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. For specific hazards statements, see Sections 7 and A1. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

It is scientifically undesirable to combine the use of two separate systems within a single asrm. 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.

Combining values from the two systems may result in non-conformance with the standard. Do not astmm this again. Username or password invalid. 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.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. Referenced Documents purchase separately The documents listed below are wstm within the subject standard but are not provided as part of the standard.

Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

The dry density of the control fraction is calculated and compared with the dry density asym established by the laboratory compaction test s. The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in.

However, for larger sized excavations, Test Method D is preferred. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. It was not possible to unsubscribe – please try again later or contact the Danish Standard Please make sure you are logged in.

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.
