It is scientifically undesirable to combine the use of two separate systems within a single standard. Link to Active This link will always route to the current Active version of the standard.

The accuracy of the test methods may be affected for d494 that deform easily or that may undergo volume change in the excavated hole from standing or walking near the hole during the 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.

Link to Active This link will always route to the current Active version of the standard. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. However, for larger sized excavations, Test Method D is preferred.

Then the material is considered to consist of two fractions, or portions. 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. Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results. Activation of monitoring failed – please try again later or contact us.

For F4914 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 In addition they are representative of the significant digits astj generally should be retained.

However, conversions are given in the SI system.

The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

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. Continue shopping Proceed to checkout.

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.

Aztm should also be firm enough not to deform or slough due to the minor pressures exerted in digging the hole and pouring the sand. Historical Version s – view previous versions of standard.

It asttm 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 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 undesirable to combine the use of two separate systems within a single standard. The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s. 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 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. 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 AetmDDand D Activation of your subscription failed – please try again later or contact us.

For specific hazards statements, see Sections 8 and A1. Active view current version of standard. The values given in parentheses are for information only. 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 However, conversions are given in the SI system.

The printed version is available at f4914 price when you buy the electronic version. In addition they are representative of the significant digits that generally should be retained.

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 d4941 standard laboratory test method such as determined from Test Method D or Dsubject to the limitations discussed in 1.
