Moisture zstm Solvent—Only specimens that are known to be thoroughly dry that is, laboratory-prepared dried specimensare to be tested in accordance with 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.
The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used.
Surface dry the specimen by blotting quickly with a damp cloth towel and then determine the mass by weighing in air. These values in turn may be used in determining the relative degree of compaction.
ASTM Volume Combining values from the two systems may result in non-conformance with the standard. Specimens shall be stored in a safe, cool place.
Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats within 0. The use of an overflow outlet is mandatory. Combining values from the two systems may result in non-conformance with the standard.
ASTM DM – 14 – Bulk Specific Gravity and Density of Non-Absorptive
The bulk specific gravity is calculated from these masses. The PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in. A superscript epsilon indicates an editorial change since the last revision or reapproval. Conversion to express the density in pounds per cubic foot is acceptable.
Density5 Bulk sp gr This interval is dependent on the size of the specimen and can be determined by experimentation and confirmed with the oven-dried comparisons. All others are assumed to contain moisture or solvent and are to be tested in accordance with Corrections shall be applied to ensure accurate measurements within 0. 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.
Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. Calibrate the thermometer in accordance with one asgm the methods in Test Method E77 or verify its original calibration at the ice point Note 4 and Note 5. Documentation must exist to validate the intervals.
This conversion is made by multiplying the specific gravity asttm a given temperature by the density of water at the same temperature.
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.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The sequence of testing for Parte 1 de 2 Designation: Designate this mass astn C.

Originally approved in Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided 2d726 part of the standard.
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. Calibrate the thermometer is accordance with one the methods in Test Method E77 or asfm its original calibration at the ice point Note 4 and Note 5.
This will make the specimen unsuitable for further testing. Designate this mass as B. NOTE 5—If the thermometer does not read 0.
