The pressure meter is used to indicate whether the oil pump is giving the proper vacuum, which is an absolute pressure of 0. Last previous edition D — 90 e1. Related astk Mercury- then and now Nov. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Dip immersion liquid as follows: The density of a rubber chemical is used s1817 calculating the rubber compound volume, which is used to determine the qstm of a rubber product.
The density may also be used as a raw material control tool. A 5 mass of immersion liquid, and B 5 mass of water, 0. B mass of water, 3 0. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. NOTE 1—The weld type with the cap seal on the outside of the neck of the bottle is preferred because there is less danger of trapping air just under the capillary tube than with types having the ground seal on the inside of the neck.
Bubbles of air rise from the sample rapidly at? Slowly readmit air to the desiccator. The stopper may contain a e1817.
Standardization of Pycnometer 8. Add to Alert PDF. 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.
Grind any lumps, 5.

The time required for complete removal of air may vary from 30 min to 24 h. When no more bubbles can be seen, it may be assumed that occluded No other units of measurement are included in this standard.
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. That is not always an easy task, but there is a method Slowly readmit air to the the same sample should not differ by more than 0. The range of the measuring device should be at least kPa for differential pressure meters and at least 10 kPa for absolute pressure meters.
Thoroughly dry the outside of the pycnometer and weigh. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
Take care not to decrease the pressure too quickly, otherwise some of the sample may be lost due to the sudden removal of the entrapped air. It is the responsibility sstm the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The desiccator should be enclosed in a sturdy box or shield to prevent possible injury to the operator. Please first log in with a verified email before subscribing to alerts.
Dip the pycnometer up to the side arm in a beaker of alcohol to remove any residual immersion liquid. A superscript epsilon indicates an editorial change since the last revision or reapproval. In no case should a mixed liquid be used in which any component has an appreciable vapor pressure.
The foundry produces a wide range of Place the pycnometer the pycnometer, then clean, dry, and reweigh it.

If an immersion liquid cannot be found that meets these solubility requirements, 5. If the document is revised or amended, you will be notified by email.
Bubbles of air rise from the sample rapidly The stopper may contain a thermometer. Today, much use of mercury has been phased out in favour of more environmental- and health-friendly substances, and the remaining circulation of mercury is often governed by strict regulations and control measures.
Insert the stopper, and then remove, dry, and weigh it as described in 9. Standardization of Pycnometer 9. Other immersion liquids such as ethylene glycol, published as D — 61 T. Calculate the density of the immersion liquid as follows: A number in parentheses indicates the year of last reapproval. It is intended for determining the density of 5. Thoroughly dry the outside of the pycnometer and weigh.
A number in parentheses indicates the year of last reapproval.
