These test methods cover the determination of the specific gravity of soil solids passing a sieve by means of a water pycnometer. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This procedure is the preferred method. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

When the soil contains particles larger than the 4. Note The use of Test Method D may be used to determine the specific gravity of soil solids having solids which readily dissolve in water or float in water, or where it is impracticable to use water. For organic soils; highly plastic, fine grained soils; tropical soils; and soils containing halloysite, Method A shall be used.

Work Item s - proposed revisions of this standard. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

ASTM D - 14 Standard Test Methods for Specific Gravity of Soil Solids by Water Pycnometer

This procedure is the preferred method. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. This abstract is a brief summary of the referenced standard. The inch-pound units given in parentheses are mathematical conversions which are provided for information purposes only and are not considered standard.

For organic soils; highly plastic, fine grained soils; tropical soils; and soils containing halloysite, Method A shall be used. Therefore, the specific gravity of soil solids containing extraneous matter, such as cement, lime, and the like, water-soluble matter, such as sodium chloride, and soils containing matter with a specific gravity less than one, typically require special treatment see Note 1 or a qualified definition of their specific gravity.

This procedure is the preferred method. Users of these test methods are cautioned that compliance with D8554 D does not in itself assure reliable results. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.

Soil solids for these test methods do not include solids qstm can be altered by these methods, contaminated with a substance that prohibits the use of these methods, or are highly organic astmm solids, such as fibrous matter which floats in water.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These test methods cover the determination of the specific gravity of soil solids passing a sieve by means of a water pycnometer.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. The method to be used shall be specified by the requesting authority, except when testing the types of soils listed in1.

Link to Active This link will always route to the current Active version of the standard. No other units of measurement are included in these test methods.

It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. When the soil contains particles larger than the 4. It is the responsibility of the user of d85 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D - 00 Standard Test Methods for Specific Gravity of Soil Solids by Water Pycnometer

The specific gravity of the soil solids at the test temperature shall be calculated from the density of the soil solids and the density of water at the test temperature or from the mass of the oven dry soil solids; mass of pycnometer, water, and soil solids at the test temperature; and mass of the pycnometer and water at the test temperature.

This is done by multiplying its specific gravity by the density of water at proper temperature. Work Item s - proposed revisions of this standard. In addition, they are representative of the significant digits that generally should be retained.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM does not give any warranty express or astmm or make any representation that the contents of this abstract are accurate, complete or up to date.

Active view current version of standard. Note 1 — The wstm of Test Method D may be used to determine the specific gravity of soil solids having solids which readily dissolve in water or float in water, or where it is impracticable to use water.

Procedures for moist specimens such as organic soils, highly plastic fine grained atsm, tropical soils, and soils containing halloysite and oven-dry specimens are provided.

The apparatus is comprised of water pycnometer which shall be a stoppered flask, stoppered iodine flask, or volumetric flask; balance; drying oven; thermometer; dessicator; a system for entrapped air removal which shall be a hot plate or Bunsen burner or a vacuum pump or water aspirator; insulated container; non-corrosive smooth surface funnel; pycnometer filling tube with lateral vents; sieve; and blender with mixing blades.

It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.
