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 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.

Wire brushing to remove paper, soil, and foil is acceptable if all traces d27226 the materials are eliminated. Documentation must exist to validate the intervals. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results.

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. The bulk specific gravity is calculated from these masses. 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 PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be at least 50 m 2 in. The interval of time between readings to determine constant mass must be sufficient to ensure that all moisture and solvent has been removed. Conversion to express the density in pounds per cubic foot is acceptable. Juliano row Enviado por: It shall be equipped with a suitable apparatus to permit weighing the specimen while suspended in water.

All others are assumed to contain moisture or solvent and are to be tested in accordance with Work Item s – proposed revisions of this standard.

A number in parentheses indicates the year of last reapproval. Surface dry the specimen by blotting quickly with a damp cloth towel and then determine the mass by weighing in air. Parte 1 de 2 Designation: These values in turn may be used in determining the relative degree of compaction. The quality of the results produced by this standard are dependent on the competence of the personnel performing the adtm and the capability, calibration, and maintenance of the equipment used.

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

Current edition approved Aug. 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 5. 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 astn 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.

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 4—Practice E provides instructions on the preparation and use of an ice-point bath as a reference temperature. Reliable asgm 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.

Historical Version s – view previous versions of standard.

Designate this mass as B. 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.

Designate this mass as A. Originally approved in This will make the specimen unsuitable for further testing. Agencies that meet the criteria of Specification D are 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. Moisture or Solvent—Only specimens that are known to be thoroughly dry that is, laboratory-prepared dried specimensare to be tested in accordance with When any of these materials are visually evident, they shall aztm removed by sawing.

Specimens shall be stored in a safe, cool place.
