Combining values from the two systems may result in non-conformance with the standard. This test method has been written using the gravitational system of units when dealing with the inch-pound system.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. It is the responsibility x the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

While the equipment illustrated in these test methods is used for volumes less than 0. The word “rock” in these test methods is used to imply that the material being tested will astmm contain particles larger than 3 in.

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

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

While the equipment illustrated in these test methods is used for volumes less than 0. 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. Then the material is considered to consist of two fractions, or portions. However, for larger sized excavations, Test Method D is preferred. Are you sure you want to unsubscribe? Kontakt venligst Dansk 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.
