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. Activation of your subscription failed – please try again later or contact us. 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 test is physically divided into a control fraction and an oversize fraction based on a designated sieve size.

Kontakt venligst Dansk Standard. The quality of 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. In this system the pound lbf represents a unit of force weight. Combining values from the two systems may result in non-conformance with the 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 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 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. In addition they are representative of the significant digits that generally should be retained.

This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. In general, the materials tested would have a maximum particle size of 3 to 5 in. Are you sure you want to unsubscribe monitoring?

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. 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 word “rock” in these test methods is used to imply that the material being tested will typically contain particles larger than 3 in.

For specific hazards statements, see Sections 7 and A1. 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.

While the equipment illustrated in these test methods is used for volumes less than 0.

Other relevant standards DS 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 Aatm D or Dsubject to the limitations discussed in 1.

This implicitly combines two separate systems of units, that is, the absolute system and the gravitational system. Active view current version of standard. Reliable testing depends on many factors; Practice D provides a means of evaluating some of those factors. It is not possible to buy in the shop – please contact us.

For Test Methods D and D only, the dry density determined in the laboratory aztm test may be corrected for larger particle sizes in accordance with, and subject to the limitations of Practice D The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

While the equipment illustrated in these test methods is used for volumes less than 1 ft 0. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. Du abonnerer astmm dette emne.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. It is undesirable to combine the use of two separate systems within a single standard. For specific hazards statements, see Sections 8 and A1.

ASTM D Standard

Then the material is considered to consist of two fractions, or portions. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. 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.

Activation of monitoring failed – please try again later or contact us. The soil or other material being tested should have sufficient cohesion or particle attraction 4194 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.

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. Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results. While the equipment illustrated in these test methods is used for volumes less than 0.

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 asstm to the limitations of Practice D
