In addition they are representative of the significant digits that generally should be retained. Then the material is considered to consist of two fractions, or portions. The printed version is available at half price when you buy the electronic astn.

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.

Are you sure you want to unsubscribe? Combining values from the two systems may result in non-conformance with the standard.

Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results. The word “rock” in these test methods is used to imply that the material being tested will typically contain particles 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.

However, conversions are given in the SI system. The values given in parentheses are for information only.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. Other relevant standards DS While the equipment illustrated in these test methods is used for volumes less than 0.

Username or password invalid. 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 unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. 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 qstm 1.

ASTM D Standard

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. For specific hazards statements, see Sections 7 and A1. It is scientifically undesirable to combine the use of two separate systems within a single standard. While the equipment illustrated in these test methods is used for volumes less than 0.

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 Please choose number of devices you want to open the document on.

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.

While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. While the equipment illustrated in these test methods is used for volumes less than 0.

In asfm, the materials tested would have a maximum particle size of 3 to 5 in. 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 d49144 particle size allowed in the laboratory compaction test refer to Test Methods DDDDand D The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

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

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

The material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through d494 of this test.

In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in.
