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.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 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 Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results.

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. 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. However, conversions are given in the SI system.

Username or password invalid. It is scientifically undesirable to combine the use of two separate systems within a single standard. Are you sure atm want to unsubscribe monitoring?

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. The word “rock” in these test methods is used to imply that the material being tested will typically contain c larger than 3 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. Active view current version of standard. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. However, for larger sized excavations, Test Method D is preferred.

The values given in parentheses are for information only. Other relevant standards DS In this system the pound lbf represents a unit of force weight. The soil or other material being tested should have sufficient cohesion or particle attraction to maintain stable sides on a small hole or excavation, and be firm enough to withstand the minor pressures exerted in digging the hole and placing the apparatus over it, without deforming or sloughing.

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

However, for larger sized excavations, Test Method D is preferred. Link to Active This link will always route to the current Active version of the 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. The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. In addition they are representative of the significant digits that generally should be 4941. For specific hazards statements, see Sections 7 and A1. Historical Version atsm – view previous versions of standard. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the users objectives; it is common practice to increase or reduce significant digits or reported data to be commensurate with these considerations.
