The accuracy of the test methods may be affected for materials that deform easily or that may undergo volume change in the excavated d414 from standing or walking near the hole during the test.

Asm 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 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.

This implicitly combines two separate systems of units, that is, the absolute system and the axtm system. These test methods have been written using inch-pound units gravimetric system where the pound lbf represents a unit of force weight.

It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. Historical Version s – view previous versions of standard.

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. In general, the materials tested would have a maximum particle size of 75 to mm [3 to 5 in. Kontakt venligst Dansk Standard.
