An error of 0. The analyzer must accommodate the accurate measurement of the 1 D5020 test asm is under the jurisdiction of ASTM Committee D02 on Petroleum Products and Lubricants and is the direct responsibility of Subcommittee D Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Work Item s – proposed revisions of this standard. Leave the syringe in place and plug the exit port.
Last previous edition approved in as D—99 Mixing is required to obtain a homogeneous sample for analysis. Although this condition can be compensated for by adjusting A and B, as described below, it is good practice to clean the tube with warm chromic acid solution Warning—Causes severe burns.
Preparation of Apparatus 9.
ASTM D5002 – 16
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Allow the water to reach thermal equilibrium at the test temperature and record the T-value for water and the test temperature. Summary of Test Method 4. The water must be free of even the smallest air or gas bubbles. Originally approved in Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
Record the T-value for air. The matrix for this bias study was comprised of 15 adtm, each analyzing four reference oils with certi? For additional information, consult the Journal of 5d002 Chemistry, Vol 84,pp. Specific warning statements are given in 7.
Calibration of Apparatus Satm crude oil can require special handling to prevent vapor losses. If the instrument has been calibrated to display the density, adjust the reading to the correct value for water at the test temperature see Table 1 by changing the value of Constant A, commencing with the last decimal place.
No other units of measurement are included in this standard. In calibrating the thermometer, the ice point and bore corrections should be estimated to the nearest 0. Continue drying until the display exhibits a steady reading.
The sample must appear to be homogeneous. Users should, therefore, be aware that results obtained by this test method can be biased by as much as 0.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? It is the astk of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The setting selected by this method could have the effect of altering the fourth place of the reading obtained for a sample.

Temperature control can be maintained as part of the density analyzer instrument package. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. NOTE 2—The need for a change in calibration is generally attributable to deposits in the sample tube that are not removed by the routine? Precision and Bias 5,6 Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Carry out all calculations to six signi? Current edition approved Sept. NOTE 3—In applying this periodic calibration procedure, it has been found that more than one value each for A and B, differing in the fourth decimal place, will yield the correct reading for the density of air and water.
Turn the illumination light off immediately after inspection of the sample tube, since the heat generated affects the measurement temperature.
In cases where saline components can be deposited in the cell,? The accepted units of measurement of density are grams per millilitre and kilograms per cubic metre.
Chromic acid solution is the most effective cleaning agent; however, surfactant-type cleaning? Lighter crude oil can require special handling to prevent vapor losses.
