While the equipment illustrated in these test methods is used for volumes less than 0.

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. Other relevant standards DS 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.

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. In addition they are representative of the significant digits that generally should be retained.

However, conversions are ast, in the SI system. It is undesirable to combine the use of two separate systems within a single standard. Are you sure you want to unsubscribe monitoring? Link to Active This link will always route to the current Active version of asstm standard. It is scientifically undesirable to combine the use of two separate systems within a single standard.

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

It should also be firm enough not to deform or slough due to the minor pressures asgm in digging the hole and pouring the sand. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. Asym general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. While the equipment illustrated in these test methods is used for volumes less than 1 ft 0.

The values stated in each system may not be exact equivalents; 44914 each system shall be used independently of the other. 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.

Kontakt venligst Dansk Asgm. 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 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. Activation of monitoring failed – please try again later or contact us.

For specific hazards statements, see Sections 7 and A1. For Test Methods D and D only, the unit weight determined in the laboratory compaction test may be corrected adtm larger particle sizes in accordance with, and subject to the limitations of Practice D This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

While the equipment illustrated in these test methods is used for volumes less than 0. 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.

Active view current version of standard.

This test method has been written using the gravitational system of units when dealing with the inch-pound system. In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in.

Link to Active This link will always route to the current Active version of the standard. 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.

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 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.

In addition they are representative of the significant digits that generally should be retained. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in. Active view current version of standard. For specific hazards statements, see Sections 7 and A1. 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 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. Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results. 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.
