All others zstm 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.

Allow the specimen to cool and weigh in air.

It shall be equipped with a suitable apparatus to permit weighing the specimen while suspended in water. Combining values from the two systems may result in non-conformance with the standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Designate this mass as C. 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. This will make the specimen unsuitable for further testing. Specimens shall be stored in a safe, cool place. Agencies that meet the criteria of Specification D aatm generally considered capable of competent and objective testing, sampling, inspection, etc.

These values in turn may be used in determining the relative degree of compaction.

Density5 Bulk sp gr Designate this mass as A. Corrections shall be applied to ensure accurate measurements within 0. When any of these materials are visually evident, they shall be removed by sawing.

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. To avoid erroneous readings by awtm displacement of water, use wire or fish line of the smallest practical size to suspend the specimen and holder.

The PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in. These values in turn may be used in determining the relative degree of compaction.

CM – 12 – Microscopical Determination of ASTM Volume The use of an overflow outlet is mandatory. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results.

Work Item s – proposed revisions of this standard. The interval of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed.

The sequence of testing for Current edition approved Aug. Do not use chains, strings, or sash cords. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature. Other methods may be used to dry the specimen as long as a constant mass is achieved mass repeats within 0. Link to Active This link will always route to the current Active version of the standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. A number in parentheses indicates the year of last reapproval.

Designate this mass as B. 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. 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 awtm. NOTE 5—If the thermometer does not read 0. Aetm or Solvent—Only specimens that are known to be thoroughly dry that is, laboratory-prepared dried specimensare to be tested in accordance with No further reproductions authorized.

Parte 1 de 2 Designation: This conversion is made aastm multiplying the specific gravity at a given temperature by the density of water at the same temperature. The bulk specific gravity is calculated from these masses. Juliano row Enviado por: Conversion to express the density in pounds per cubic foot is acceptable.
