Work Item astm d7263 – proposed revisions of this standard. Specimens that are remolded by dynamic or static compaction procedures may also be measured by these methods. These methods apply to soils that will retain their shape during the measurement process and may also apply to other materials such as soil-cement, astm d7263, soil-bentonite or e7263 soil-bentonite-cement slurries.

Sstm specimens astm d7263 be obtained from thin-walled sampling tubes, block samples, or clods. The values stated in inch-pound units are approximate. It d72263 the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Ahairnet may astm d7263 be used in lieu of the basket for smaller soil specimens. Since moisture content is variable, moist soil density provides little useful information except to estimate the weight of soil per unit volume, for example, pounds per cubic yard, at the time of sampling.

Wet soils tend to be more plastic and subject to compression.

Re-entrant a ngles should be avoided, and any cavities formed by l arge particles being pulled out should be patched carefully with mat erial from the trimmings.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and astm d7263 the applicability of regulatory limitations prior asm use. Users of this standard astm d7263 cautioned that compliance c7263 PracticeDdoes not in itself assure reliable results.
