When any of these materials are visually evident, they shall be removed by sawing. Wire brushing to remove paper, soil, and foil is acceptable if all traces of the materials aatm eliminated.

Designate this mass as C. The mass under water is recorded, and the specimen is taken out of d22726 water, blotted quickly with a damp cloth towel, and weighed in air. Documentation must exist to validate the intervals. CM – 12 – Microscopical Determination of A number in parentheses indicates the year of last reapproval.

It shall be equipped with a suitable apparatus to permit weighing the specimen while suspended in water. Density5 Bulk sp gr D27266 superscript epsilon indicates an editorial change since the last revision or reapproval. 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. Specimens shall be stored in a safe, cool place.

Historical Version s – view previous versions of standard. Designate this mass as B. Conversion to express the density in pounds per cubic asfm is acceptable. The interval of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed.

Do not use chains, strings, or sash cords.

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. Current edition approved Aug. This interval is dependent on the size of the specimen and can be determined by experimentation and confirmed with the oven-dried comparisons. Moisture or Solvent—Only specimens that are known to be thoroughly dry that is, laboratory-prepared dried specimensare to be tested in accordance with Corrections shall be applied to ensure accurate measurements within 0.

Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats 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.

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

NOTE 5—If the thermometer does not read 0. ASTM Volume Link to Active This link will always route to the current Active version of the standard. Allow the specimen to cool and weigh in air. Combining values from the two systems may result in non-conformance with the standard. Juliano row Enviado por: All others are assumed to contain moisture or solvent and are to be tested in accordance with 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.

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 1.

These values in turn may be used in determining the relative degree of compaction. Originally approved in The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

These values in turn may be used in determining the relative degree of compaction. Combining values from the two systems may result in non-conformance with the standard.

Work Item s – proposed revisions awtm this standard. 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. The PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability astn regulatory limitations prior to use.

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 use of an overflow outlet is mandatory. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.
