Hence, the water content of the soil should be determined at the time of sampling. These methods apply to asym that will retain their shape astm d7263 the measurement process and may also apply to other materials such as soil-cement, soil-lime, soil-bentonite or solidified soil-bentonite-cement slurries. Precision and Bias 3 5 where: NOTE satm soilspecimen,it may cause the moisture to vaporize and form air bubbles under the astm d7263.
This is due to the specimen swelling astm d7263 removal of lateral pressures.
NOTE 5—Maintainwaterbathtemperatureandsubmergedbasketdepth the same as when calibrated or z eroed. The values stated in inch-pound units are approximate. 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. Specimens are usually cubical or astm d7263 in shape. Ahairnet may also be used in lieu of the basket for smaller soil specimens.
This is due to astm d7263 specimen astm d7263 after removal of lateral pressures. NOTE 7—Coresamplingmightbedifficultorimpossibleingravelly or hard dry soils.
It is the responsibility of the user of this standard astm d7263 establish appropriate safety, health, and environmental astm d7263 and determine the applicability of regulatory limitations prior to use. Reliable results depend on several factors; Practice Dprovides a means of evaluating some of d7236 factors. Work Item s – proposed revisions of this standard.

In order to directly measure the submergedmassofthewetsoilandwax,thebalancemusthave been astm d7263 balanced tared to zero with the wire basket completely submerged in the container of water. Dry density measurements are also useful for determining degree of soil compaction.
Current edition approved March 15, Intact specimens may be obtained from thin-walled sampling tubes, block samples, astm d7263 clods.

These methods apply to astm d7263 that will retain their shape during the measurement process and may also apply to other materials such as soil-cement, soil-lime, soil-bentonite or solidified soil-bentonite-cement slurries.

After a specimen is formed, astm d7263 if necessary the ends perpendicular to the longitudinal axis, remove astm d7263 mold, and determine the d723 and dimensions of r7263 test specimens inaccordancewith7. The values given in parentheses after SI units are provided for information only and are not considered standard.

Acontainerheatedbyhot water, preferably thermostatically controlled, is satisfactory. Intact specimens may be obtained from thin-walled sampling tubes, block samples, or clods. Wet soils tend astm d7263 be more plastic and subject to compression. Intact specimens may be obtained from thin-walled sampling tubes, block samples, or clods. If required, trim the specimen to a fairly regular shape. It is common for the density unit weight of specimens after removal from sampli ng tubes and compaction molds to be less than the value based on tube or mold volumes, or of in-situ conditions.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This is due to the astm d7263 swelling after removal of lateral pressures. How one applies the results obtained astm d7263 this standard is beyond its scope. Specimens that are satm by dynamic or static compaction procedures may also be measured by these methods.
