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

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 4194 not exceed the maximum particle size allowed in the laboratory compaction test refer xstm Test Methods DDDDand D For specific hazards statements, see Sections 8 and A1. Active view current version of standard. Combining values from the two systems may result in non-conformance with the x.

It is not possible to buy in the shop – please contact us. 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 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 unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. 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 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 undergo volume change in the excavated hole from standing or walking near the hole during the test.

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.

It is undesirable to combine the use of two separate systems within a single standard.

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

However, for larger sized excavations, Test Method D is preferred. Other relevant standards DS You must be logged in to sign up for monitoring You must be ashm in to sign up for subscription.

The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, asym 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. Then the material is considered to consist of two fractions, or portions.

For specific hazards statements, see Sections 7 and A1. 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 494 laboratory compaction test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D The printed version is available at half price when you buy the electronic version.

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 However, for larger sized excavations, Test Method D is preferred.

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 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 unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. It was not possible to unsubscribe – please try again later or contact the Danish Standard Please make sure you are logged in.

In this system 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. 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.

Username or password invalid. 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. However, conversions are given in the SI system. The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s.

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