These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

While the equipment illustrated in these test methods is used for volumes less than 0. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. For specific hazards statements, see Sections 7 and A1. 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.

Combining values from the two systems may result in non-conformance with the standard. However, conversions are given in the SI system.

Username or password invalid. 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.

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. In addition they are representative of the significant digits that generally should be retained.

However, for larger sized excavations, Test Method D is preferred. The values given in parentheses are for information only. Active view current version of standard. It should also be firm enough zstm to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand.

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 unit weight determined in the laboratory compaction test may be corrected for larger particle sizes in accordance with, 9414 subject to the s of Practice D You must be logged in to sign up for monitoring You must be logged in to sign up for subscription.

In this system the pound lbf represents a unit of force weight. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. In general, the materials tested would have a maximum particle size atsm 75 to mm [3 to 5 in. 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 asm standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 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 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 accuracy of the test methods may astj affected for materials that deform easily or that may undergo volume 4194 in the excavated hole from standing or walking near the hole during the test.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

This test method has been written using the gravitational system of units when dealing with the inch-pound 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 Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results.
