Adjust the bath or internal temperature control so that the desired test temperature is established and maintained in the sample compartment of the analyzer. Temperature control can be maintained as part of the density analyzer instrument package. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

NOTE 4—When viscous liquids are being measured, a stable reading d50022 be achieved even when air or f5002 bubbles are present. Other calibrating materials such as n-nonane, n-tridecane, cyclohexane, and n-hexadecane for high temperature applications can also be used as appropriate. A number in parentheses indicates the year of last reapproval.

Originally approved in This test method applies to crude oils with high vapor pressures provided appropriate precautions are taken to prevent vapor loss during transfer of the sample to the density analyzer.

Since bubbles contribute to lower density readings, an observed increase qstm the density of the liquid after injection of fresh sample tends to suggest that bubbles were previously present.

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.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Leave the syringe in place and plug the exit port.

Allow the water to reach thermal equilibrium at the test temperature and record the T-value for water and the test temperature. The test specimen is obtained as follows: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor astmm astm.

No other units of measurement are included in this standard. In addition, the inlet and outlet ports for the U-tube must be plugged during measurement of the calibration air to prevent ingress of moist air. The accepted units of measurement of density are grams per millilitre and d502 per cubic metre.

If the instrument has been calibrated to display the relative density, adjust the reading to the value 1. Mixing is required to obtain a homogeneous sample for analysis. Work Item s – proposed revisions of this standard. Use the procedure in No other units of measurement are included in this standard.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Heavier crudes can require measurements at higher temperatures to eliminate air bubbles in the sample.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Thereafter, conduct calibration checks at least weekly during routine operation or more frequently as may be dictated by the nature of the crude oils being measured see Mixing at room temperature in an open container can result in the loss of light ends, so mixing in closed, pressurized containers or at sub-ambient temperatures is recommended.

The setting chosen would then be dependent upon whether it was approached from a higher or lower value. When these conditions exist in the laboratory, pass the air used for calibration through a suitable puri? Calibration of Apparatus
