More D The handling of samples from the time of collection until they are analyzed requires care and effort to maintain their compositional integrity. Samples of high RVP unstabilized hydrocarbons are required at many measurement points, for example offshore production, at the outlets of test separators or to allow calibration of a flowmeter. This practice also describes requirements associated with handling and mixing samples held within pressurized cylinders. The primary purpose of this suite of standards, is to ensure proper sampling and handling for custody transfer applications. For samples that are taken for test methods outside the general scope of custody transfer covered by this practice, the personnel assigned to take the sample are responsible to refer to the test methods for additional critical information that may impact the sampling process, that is, specific container selection, transport methods, storage times, etc.

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

Procedures for moist specimens such as organic soils, highly plastic fine grained soils, 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.

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. Precision and bias shall be determined to judge for the acceptability of the test results. This abstract is a brief summary of the referenced standard.

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. 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. Significance and Use 4. This is done by multiplying its specific gravity by the density of water at proper temperature.

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.

Note 2—The quality of the result produced by these test methods is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

Users of these test methods are cautioned that compliance with Practice D does not in itself assure reliable results. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Scope 1. When the soil contains particles larger than the 4. Note 1—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.

The method to be used shall be specified by the requesting authority, except when testing the types of soils listed in 1. This procedure is the preferred method. For organic soils; highly plastic, fine grained soils; tropical soils; and soils containing halloysite, Method A shall be used. In addition, they are representative of the significant digits that generally should be retained.

It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. The inch-pound units given in parentheses are mathematical conversions which are provided for information purposes only and are not considered standard. 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.



Mehn Note 1 — 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 axtm, or where it is impracticable to use water. When the soil contains particles larger than the 4. Consequently, the production of coal combustion ash CCA as a by-product of coal utilization as primary energy sources was increased. ASTM D — 00 Standard Test Methods for Specific Gravity of Soil Solids by Water Pycnometer Co-placement experiment with mudstone waste rock shows that the CCA, though it has limited contribution to the decreasing permeability, has important contributed to increase the quality of leachate through releasing higher alkalinity. Work Item s — proposed revisions of this standard.
