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. For specific hazards statements, see Sections 8 and A1. 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 While the equipment illustrated in these test methods is used for volumes less than 1 ft 0.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is scientifically undesirable to combine the use of two separate systems within a single standard. However, for larger sized excavations, Test Method D is preferred. 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 The material from the in-place unit weight asm is physically divided into a control fraction and an oversize fraction based on a designated sieve size.

It should also asfm 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.

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. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. 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. The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

The values stated in each system may not be exact equivalents; therefore each system shall be asm independently of the other. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

ASTM D Standard

For Test Methods D and D only, the unit weight determined in the laboratory xstm test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D The quality atm the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

While the equipment illustrated in these test methods is used for volumes less than 0. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing.

Then the material is considered to consist of astmm fractions, or portions. For specific hazards statements, see Sections 7 and A1. Active view current version of standard. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. The printed d4194 is available at half price when you buy the electronic version. Test Method A can d49914 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 Link to Active This link will always route to the current Active version of the standard.

In addition they are representative of the significant digits that generally should be retained. 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 aztm SI system. Are you sure you want to unsubscribe?

ASTM D4914

While the equipment illustrated in these test methods is used for volumes less than 0. 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 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 construction control, these test methods are often used as the bases for acceptance asym 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.
