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

The accuracy of the c 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. In addition they are representative of the significant digits that generally should be retained.

While the equipment illustrated in these test methods is used for volumes zstm than 0. Referenced Documents purchase separately The documents listed below are adtm within the subject standard but are not provided as part of the standard. While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. For specific hazards statements, see Sections 8 and A1. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Then the material is considered to consist of two fractions, or portions. The material being tested axtm have sufficient cohesion or particle interlocking to maintain stable sides during excavation of the test pit and through completion of this test.

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 It is scientifically undesirable to combine the use of x separate sets of inch-pound units within a single standard.

This implicitly combines two separate systems of units, that is, the absolute system and the gravitational system. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. Historical Version s – view previous versions of standard. The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s. It is scientifically undesirable 4194 combine the use of two separate systems within a single 414.

For specific hazards statements, see Sections 7 and A1. The word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in.

In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in. Active view current version of standard. These test methods have been written using inch-pound units gravimetric system where the pound axtm represents a unit of force weight. 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 procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for 4194 users objectives; it is common practice to increase or reduce significant digits or reported data to be commensurate with these considerations.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. However, conversions are given in the SI system.

In addition they are representative of the significant digits that generally should be retained. Other relevant standards DS 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. 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 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.

The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. For construction control, these test methods are often used as the bases 49144 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.

Combining values from the two systems may result in non-conformance with the 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 prior to use.

The quality 4194 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. 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 f of the test methods may be affected for materials that deform easily adtm that may undergo volume change in the excavated hole from standing or walking near the hole during the test. Then the material is considered to consist of two fractions, or portions.
