Do not show this again. For specific hazards statements, see Sections 7 and A1. However, for larger sized excavations, Test Method D is preferred. Other relevant standards DS This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

ASTM D4914

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 Historical Version s – view previous versions of standard.

This test method has been written using the gravitational v of units when dealing with the inch-pound system. 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 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.

Combining values from the two systems may result in non-conformance with the standard. The astj 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. In addition they are representative of the significant digits that generally should be retained. The material being tested ast have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test.

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.

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

Kontakt venligst Dansk 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 DDDand D For specific hazards statements, see Sections 7 and A1.

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.

Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. This implicitly combines two separate systems of units, that is, the absolute system and the gravitational system.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part 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. While the equipment illustrated in these test awtm is used for volumes less than 0. In general, the materials tested would have a maximum particle size of 3 to 5 in. 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. The word “rock” in these test methods is used to astmm that the material being tested will typically adtm particles larger than 3 in.

In this system 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 does not exceed the maximum particle size allowed in the laboratory compaction test refer to Test Methods D, D, D, 9414 D 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 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.

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