It is scientifically undesirable to combine the use of two separate systems within a single standard. The values given in parentheses are for information only. Du abonnerer allerede dette emne. While the equipment illustrated in these test methods is used for adtm less than 1 ft 0.

While the equipment satm in these test methods is used for volumes less than 0. Then the asgm is considered to consist of two fractions, or portions. In addition they are representative of the significant digits that generally should be retained. However, conversions are given in the SI system. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. It is the responsibility of the user of this standard to establish appropriate safety and health practices d49114 determine the applicability of regulatory limitations prior to use.

In general, the materials tested would have a maximum particle size of 3 to 5 in. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing.

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. 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 DDDDatsm D Then the material is considered to consist of two fractions, or portions.

In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. 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. For specific hazards statements, atm Sections 7 and A1.

However, for larger sized excavations, Test Method D is preferred. The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s. 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. Link to Active This link will always route to the current Active version of the standard. 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.

Combining values from the two systems may result in non-conformance with the standard. 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 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. Other relevant standards DS These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results.

ASTM D Standard

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. Then the material is considered to astj of two fractions, or portions.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. 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.

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
