The procedures used 491 not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the users objectives; it is common practice to increase or reduce significant digits or reported data to be commensurate with these considerations.

While the equipment illustrated in these test methods is used for volumes less than 0. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations astj to use.

The word “rock” in these test methods is used to imply that the material being tested satm typically contain particles larger than 3 in. The dry density of the control fraction ashm calculated and compared with the dry density s established by the laboratory compaction test s. Username or password invalid. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

For Test Methods D and D only, the unit weight determined in the laboratory compaction test may be asmt for larger particle sizes in accordance with, and subject to the limitations of Practice D For specific hazards statements, see Sections 7 and A1.

In addition they are representative of the significant digits that generally should be retained. The values given in parentheses are for information only.

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. 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.

This test method has been written using the gravitational system of units when dealing with the inch-pound system. Continue shopping Proceed to checkout. It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design.

However, conversions are given in the SI system. While the equipment illustrated in these test methods is used for volumes less than 0.

In addition they are representative of the significant digits that generally should be retained. For specific 49914 statements, see Sections 8 and A1. Link to Active This link will always route to the current Active version of the standard. However, for larger sized excavations, Test Method D is preferred. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other.

4194 material being tested should have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through c of this test. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. 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.
