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.

Allow the specimen to cool and weigh in air. A superscript epsilon indicates an editorial change since the last revision or reapproval.

The interval of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed. The bulk specific gravity is calculated from these masses. NOTE 4—Practice E provides instructions on the preparation and use of an ice-point bath as a reference temperature.

This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.

Current edition approved Aug. CM – d226 – Microscopical Determination of These values in turn may be used in determining the relative degree of compaction. 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.

Juliano d27726 Enviado por: A number in parentheses indicates the year of last reapproval. 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. Parte 1 de 2 Designation: 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.

To avoid erroneous readings by undue displacement of water, use wire or fish line of the smallest x2726 size to suspend the specimen and holder. Originally approved in Surface dry the specimen by s2726 quickly with a damp cloth towel and then determine the mass by weighing in air.

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.

Corrections shall be applied to ensure accurate measurements within 0. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature. For example, a sensitivity of 0.

Calibrate the thermometer in accordance with one of the methods in Test Method E77 or verify its original calibration at the ice point Note 4 and Note 5. This will make the specimen unsuitable for further testing.

It shall be equipped with a suitable apparatus to permit weighing the specimen while suspended in water. 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.

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 ASTM Volume Documentation must exist to validate the intervals.

The results of two properly conducted tests on the same material, by the same operator, using the same equipment, should be considered suspect if they differ by more than the d2s single operator limits shown in Table d726. Density5 Bulk sp gr The PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in. Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats within 0.

The mass under water is recorded, ast the specimen is taken out of the water, blotted quickly with a damp cloth towel, and weighed in air.
