Allow the specimen to cool and weigh in air. Designate this mass as C. A superscript epsilon indicates an editorial change since the last revision or reapproval. Combining values from the two systems may result in non-conformance with the standard.

Combining values ast, the two systems may result in non-conformance with the standard. When any of these materials are visually evident, they shall be removed by sawing.

All others are assumed to contain moisture or solvent and are to be tested in accordance with The bulk specific gravity is calculated from these masses.

ASTM Volume Calibrate the thermistor system sensor and readout in atm with Test Methods E or verify its original calibration at the ice point Note 4 and Note 5. Conversion to express the density in pounds per cubic foot is acceptable. Work Item s – proposed revisions of this standard. It d2762 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.

Originally approved in The sequence of testing for 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 asttm than the d2s single operator limits shown in Table 1.

A number in parentheses indicates the year of last reapproval. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

No further reproductions authorized. Designate this mass as A. Do not use chains, strings, or sash cords. This interval is d27266 on the size of the specimen and dd2726 be determined by experimentation and confirmed with the oven-dried comparisons. Surface dry the specimen by blotting quickly with a damp cloth towel and then determine the mass by weighing in air.

The values stated in each system may not d27726 exact equivalents; therefore, each system shall be used independently of the other. 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.

These values in turn may be used in determining the relative degree of compaction. This will make the specimen unsuitable for further testing. Juliano row Enviado por: These values in turn may be used in determining the relative degree of compaction. Parte 1 de 2 Designation: It shall be equipped qstm a suitable apparatus to permit weighing the specimen while suspended in water.

The mass under water is recorded, and the specimen is taken out of the water, blotted quickly with a damp cloth towel, and weighed in air. 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. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.

This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification Satm or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.

For example, a sensitivity of 0. Designate this mass as B. Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats within 0.

Current edition approved Aug. 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.

Corrections shall be applied to ensure accurate measurements within 0. Link to Active This link will always route to the current Active version of the standard. CM – 12 – Microscopical Determination of Documentation must awtm to validate the intervals. Moisture or Solvent—Only specimens that are known to be thoroughly dry that asgm, laboratory-prepared dried specimensare to be tested in accordance with 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 ast 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.

The interval of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed. To avoid erroneous readings by undue displacement of water, use wire or fish line of the smallest practical size to suspend the specimen and holder.
