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.

A number in parentheses indicates the year of last reapproval. Designate this mass as A.

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. ASTM Volume Juliano row Enviado por: Corrections shall be applied to ensure accurate measurements within 0.

Density5 Bulk sp gr The results of two properly conducted tests on the same material, by the same operator, using the same equipment, r2726 be considered suspect if they differ by more than the d2s single operator limits shown in Table 1. The use of an overflow outlet is mandatory. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine axtm applicability of regulatory limitations prior to use.

Asmt not use chains, strings, or sash cords. Surface dry the specimen by blotting quickly with d27266 damp cloth towel and then determine the mass by weighing in air. Dd2726 bulk specific gravity is calculated from these masses. Documentation must exist to validate the intervals. NOTE 4—Practice E provides instructions on the preparation and use of an ice-point bath as a reference temperature. Historical Version s – view previous versions of standard. Combining values from the two systems may result in non-conformance with the standard.


Parte 1 de 2 Designation: Conversion to express the density in pounds per cubic foot is acceptable. 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.

Link to Active This link will always route to the current Active version of the standard. 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. Designate this mass as B. Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results.

These values in turn may be used in determining the relative degree of compaction. 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 d7226 Note 5. Work Item s – proposed revisions of this standard. The values s2726 in each system may not be exact equivalents; therefore, each system shall be used independently of the other.


The sequence of testing for 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. No further reproductions authorized.

This interval is dependent on the size of the specimen and can be determined by experimentation and confirmed with the oven-dried comparisons. The Aastm shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in.

NOTE 2—Since there are no more significant figures in the quotient bulk specific gravity than appear in d7226 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 asm 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.

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