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 should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.

Then the material is considered to consist of two fractions, or portions. However, conversions are given in the SI system. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. Link to Active This link will always route to the current Active version of the standard. 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.

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 during the test.

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 quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Username or password invalid. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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 DDDDand D You must be logged in to sign up for monitoring You must be logged in to sign up for subscription.

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 DDDand D 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 asym that deform easily or that may undergo volume change in the excavated hole from standing or walking near the hole during the test. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

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 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.

The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. Test Method A can also be used to determine percent sstm 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 It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.
