All others are assumed to contain moisture or solvent and are to be tested in accordance with This conversion is made by multiplying the specific gravity at a given temperature by aztm density of water at the same temperature. No further reproductions authorized.

The quality of the results produced ast this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. It shall be equipped with a suitable apparatus to permit weighing the specimen while suspended in water.

To avoid erroneous readings by undue displacement of water, use wire or fish line of the smallest practical size to suspend atsm specimen and holder. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Designate this mass as A.

Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results. A superscript epsilon indicates an editorial change since the last revision or reapproval. Designate this mass as C. Combining values from the two systems may result in non-conformance with the standard.

For example, a sensitivity of 0. Reliable results depend on many factors; following the suggestions of Specification D or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.

Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. Corrections shall be applied to ensure accurate measurements within 0. Documentation must exist to validate the intervals.

The PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in. Calibrate the thermometer is accordance with one the methods in Test Method E77 or verify its original calibration at the ice point Note 4 and Note 5.

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.

Calibrate the thermistor system sensor and readout in accordance with Test Methods E or verify its original calibration at the ice point Note 4 and Note 5. Juliano row D22726 por: NOTE 5—If the thermometer does not read 0.

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.

Current edition approved Aug. These values in turn may be used in determining the relative degree of compaction. Designate this mass as B. Originally approved in This interval is dependent on the size of the specimen and can be determined by experimentation and confirmed with the oven-dried comparisons.

The sequence of testing for When any of these materials are visually evident, they shall be removed by sawing. Allow the specimen to cool and weigh in air. Historical Version s – view previous versions of standard.

ASTM DM – 14 – Bulk Specific Gravity and Density of Non-Absorptive

NOTE 2—Since there are no more significant figures in the quotient bulk specific gravity than appear in either the dividend the mass of the specimen in air or in the divisor the mass of the volume of water equal to the volume of the specimen, obtained from the difference in weight of the saturated surface-dry specimen in air and in waterthis means that the balance must have a sensitivity capable of providing both mass values to at least four figures.

Surface dry the specimen by blotting quickly with a damp cloth towel and then determine the mass by weighing in air.

Parte 1 de 2 Designation: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. ASTM Volume Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats within 0. The interval of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed.
