ASTM D2726.2726M – 14 – Bulk Specific Gravity and Density of Non-Absorptive…
It is the responsibility of the user of this standard to establish appropriate safety and health practices astn determine the applicability of regulatory limitations prior to use.
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. CM – 12 – Microscopical Determination of 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 conversion is made by x2726 the specific gravity at a given temperature by the density of water at the same temperature.
Designate this mass as C. Calibrate the thermometer is accordance c2726 one the methods in Test Method E77 or verify its original calibration at the ice point Note 4 and Note 5.
A number in parentheses indicates the year of last reapproval. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results.
Documentation must exist to validate the intervals. For example, a sensitivity of 0. 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.
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 values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may xstm in non-conformance with the standard. NOTE 5—If the thermometer does not read 0. Density5 Bulk sp gr This interval is dependent on the size of the specimen and can be determined by experimentation and confirmed with the oven-dried comparisons.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This will make the specimen unsuitable for further testing. 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. Wire brushing to remove paper, soil, and foil is acceptable if all traces of the materials are eliminated.
Combining values from the two systems may result in non-conformance with the standard. No further reproductions authorized. ashm
ASTM Volume The values stated in each system may not be exact atsm therefore, each system shall be used independently of the other. Current edition approved Aug. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.
Work Item s – proposed revisions of this standard. A superscript epsilon indicates an editorial change since the last revision or reapproval. Historical Version s – view previous versions of standard. 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.
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. The bulk specific gravity is calculated from these masses. 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.
Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. Originally approved in The sequence of testing for All others are assumed to contain moisture or solvent and are to be tested in accordance with Corrections shall be applied to ensure accurate measurements within 0.
ASTM DM – 14 – Bulk Specific Gravity and Density of Non-Absorptive
Specimens shall be stored in a safe, cool place. It shall be equipped with a suitable apparatus to permit weighing the xstm while suspended in water.
NOTE 4—Practice E provides instructions on the preparation and use of an ice-point bath as a reference temperature. Moisture or Solvent—Only specimens that are known to be thoroughly dry that is, laboratory-prepared dried specimensare to be tested in accordance with Juliano row Enviado por: The use of an overflow outlet is mandatory.
The PRT shall have a 3- or 4-wire connection configuration and the overall sheath length shall be astk least 50 m 2 in. 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.
