A superscript epsilon indicates an editorial change since the last revision or reapproval. 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.
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. The mass under water is recorded, and the specimen is taken out of the water, blotted quickly with a damp cloth towel, and weighed asstm air.
When any of these materials are visually evident, they shall be removed by sawing. 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.
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 the density of water at the same temperature.
Do not use chains, strings, or sash cords. Parte 1 de 2 Designation: 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 values stated in each system may not be exact d27266 therefore, each system shall be used independently of the other.
Designate this mass as C. 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. NOTE 5—If the thermometer does not read 0.
Corrections shall be applied to ensure accurate measurements within 0. For example, a sensitivity of 0. This conversion ast made by multiplying the specific gravity at a given temperature by the density of water at the same temperature. Juliano row Enviado por: The bulk specific gravity is calculated from these masses.
No further reproductions authorized.

It shall be equipped with a suitable apparatus to permit weighing the specimen while suspended in water. Density5 Bulk sp gr 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 d2762 of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed.
Documentation must exist to validate the intervals.
Current edition approved Aug. Allow the specimen to cool and weigh in air.

Combining values from the two systems may result in non-conformance with the standard. Moisture or Solvent—Only specimens that are known to be thoroughly dry that is, laboratory-prepared dried specimensare to be tested in accordance with Specimens shall be stored in a safe, cool place. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard.
Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats within 0. 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. Wire brushing to remove paper, soil, and foil is acceptable if all traces of the materials are eliminated. This will make the specimen unsuitable for further testing.
Work Item s – proposed revisions of this standard. CM – 12 – Microscopical Determination of The use of an overflow outlet is mandatory.
