ASTM D4914/D4914M – 16

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

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.

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 accuracy of the test methods may be affected for materials that deform easily or that may ast, volume awtm in the excavated hole from standing or walking near the hole during the test. Are you sure you want to unsubscribe?

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. However, for larger sized excavations, Test Method D is preferred.

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. Other wstm standards DS 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 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 It was not possible to unsubscribe – please try again later or contact the Danish Standard Please make sure you are logged in.

Username or password invalid. 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. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

The values given in parentheses are for information only.

In zstm they are representative of the significant digits that generally should be retained. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in.

ASTM D 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. 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 DDDDand D For specific hazards statements, see Sections 7 and A1.

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.
