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

While the equipment illustrated in these test methods is used for volumes less than 0. 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.

Then the material is considered to consist of two fractions, or portions. Link to Active This link will always route to the current Active version of the standard.

ASTM D4914/D4914M – 16

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. Are you sure you want to unsubscribe?

The material v4914 the in-place unit weight test is physically divided into a control fraction and an oversize fraction based on a designated sieve size.

It is beyond the d49114 of this standard to consider significant digits used in analytical methods for engineering design. Please choose number of devices you want to open the document on.

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

While the equipment illustrated in these test methods is used for volumes less x4914 0. However, conversions are given in the SI system. 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 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 values stated in each system may not be dd4914 equivalents; therefore each system shall be used independently astk the other.

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.

Test Method A can also be used to determine percent compaction or percent relative density when the maximum particle size atsm in the in-place asrm being tested does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods D, D, D, and D Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. 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 the responsibility of the user of this standard to establish appropriate safety atsm health practices and determine the applicability of regulatory limitations prior to use.
