This astm d7263 done by placing the specimen in a wire basket hookedontoabalanceandimmersingthebasketandspecimen in a container of water. ASTM D – Reliable results depend on several factors; Practice Dprovides astm d7263 means of evaluating some of these factors. NOTE 8—Some soils may expand into asym sampling tube with a resultant change in volume from the original in-situ condition.

Terminology NOTE 2—The waxes generally used are commercially available and 3 have density values in the range of 0. Intact specimens may be obtained from thin-walled astm d7263 tubes, block samples, or astm d7263. Since soil volume shrinks with drying of swelling soils, bulk density will vary with moisture content.

Reliable results depend on several factors; Practice D provides a means of evaluating some of astm d7263 factors. This is due to the specimen swelling after removal of lateral d72263.

Users of this standard are cautioned that compliance with PracticeDdoes not in itself assure reliable results. The height astm d7263 inner dimensions of the tube may be taken to represent specimen dimensions.

It can bepeeled off after a astm d7263 is made in the wax surface. The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Work Item s – proposed revisions of astm d7263 standard.

For methodA, the balance must be capable of measuring the mass 3 NOTE 3—Circumferentialmeasuringtapesarerecommendedovercalipers astm d7263 measuring the diameter of cylindrical specimens. Hence, the water content of the soil astm d7263 be determined at the time of sampling.

Dry density measurements are al so useful for determiningdegreeofsoilcompaction.

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, aztm, soil-bentonite or solidified soil-bentonite-cement slurries.

Astm d7263 are usually cubical or cylindrical in shape. This is due to the specimen swelling after removal satm lateral pressures. Noteinthereportif watercontent is not from the specimen itself. When particle density, that is, specific gravity Test Methods D is also known, dry density can be used to calculate porosity and void ratio see Appendix X1. The values given in parentheses after SI units are provided for information only and are not considered standard.

It is common for the density astm d7263 weight of specimens after removal from sampling tubes and astm d7263 molds to be less than the value based on tube or mold volumes, or of in situ conditions.

If required, trim the specimen to a fairly regular shape. It is the responsibility of the user of this ast, to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
