It is scientifically undesirable to combine the use of two separate systems within a single standard. However, for larger sized excavations, Test Method D is preferred.

Are you sure you want to unsubscribe monitoring? 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. Combining values from the two systems may result in non-conformance with the standard. This implicitly combines two separate systems of units, aastm 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. Reliable testing depends on many factors; Practice D provides a means of evaluating astk of those factors.

ASTM D4914/D4914M – 16

In general, the materials tested would have a maximum particle size of 75 to mm 3 to 5 in. 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 undesirable to combine the use of two separate systems within a single 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 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.

However, for larger sized excavations, Test Method D is preferred.

The accuracy of the test d44914 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 1 ft 0.

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.

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

However, conversions are given in the SI system. 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.

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 Then the material is considered to consist of two fractions, or portions.

The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. 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 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. In addition they are representative of the significant digits that generally should be retained. Active view current version of standard.
