Then the material is considered to consist of two fractions, or portions. This implicitly combines two separate systems of units, that is, the absolute system and the gravimetric system. The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s.

Historical Version s – view previous versions of standard. In addition they are representative of the significant digits that generally should be retained. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

However, conversions are given in the SI system. Other relevant standards DS 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 imply that the material being tested will typically contain particles larger than 3 in.

It is undesirable to combine the use of two separate systems within a single standard. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight. The printed version is available at half price when you buy the electronic version. Then the material is considered to consist of two fractions, or portions.

It is scientifically undesirable to combine the use of two separate systems within a single standard. Link to Active This link will always route to the current Active version of the standard. Agencies that meet the criteria of Practice D are generally considered capable of competent and objective testing. 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.

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

ASTM D Standard

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. Active view current version of standard. This implicitly combines two separate systems of units, that is, the absolute system and the gravitational system.

In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Link to Active This link will always route to the current Active version of 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 astmm being tested does not exceed the maximum particle size allowed asttm the laboratory compaction test refer to Test Methods DDDand D Active view current version of standard.

In addition they are representative of the significant digits that generally should be retained. The material from the in-place unit weight test is physically divided into a control fraction and 4941 oversize fraction based on a designated sieve size.

This test method has been written using the gravitational system of units when dealing with the inch-pound system. For Test Methods Aatm 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 While the equipment illustrated in these test methods is used for volumes less than 0.

The procedures used do 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.

The dry density of the control fraction is calculated and compared with the dry density s established by the laboratory compaction test s. The unit weight of the control fraction is calculated and compared with the unit weight s established by the laboratory compaction test s. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. This implicitly combines two separate systems of units, that atm, the absolute system and the gravimetric system.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in. 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.

Then the material is considered to consist of two fractions, or portions. However, for larger sized excavations, Test Method D is preferred. Users of these test methods are cautioned that compliance with Practice D does not in itself ensure reliable results. Username or password invalid. 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.
