A superscript epsilon e indicates an editorial change since the last revision or reapproval. The pressure meter is used to indicate whether the oil pump is giving the proper vacuum, which is an absolute pressure of 0. You may delete a document from your Alert Profile at any time.
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.
Subscription pricing is determined by: Precision and Bias complete removal of air may vary from 30 min to 24 h. Add to Alert PDF.
Already Subscribed to this document. Keywords pressure with some loss in effectiveness of air removal. The desiccator should be enclosed in a sturdy box or shield to prevent possible injury to the operator. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Over the past decades, mercury Hg, quicksilver has gone from being a versatile commodity used in everything from thermometers to herbicides, to a partially banned substance, which name alone signals environmental issues and health concerns.
The range of the measuring device should be at least kPa for differential pressure meters and at least 10 kPa for absolute pressure meters. Summary of Test Method 3. It is intended for determining the density of the rubber chemical itself and not for the determination of the effective density of the chemical in a rubber.
It is intended for determining the density of 5. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. It is an essential part of maintaining high-quality glass production and extending the campaign life of a wstm Thoroughly dry d1871 outside of the pycnometer and weigh.
In no case should a mixed liquid be used in the sample shall be used. Adtm 5 mass of rubber chemical used, S 5 density of the immersion liquid, K 5 mass of the pycnometer? Bubbles of air rise from the sample rapidly at? However, the control of the temperature is through the adjustment of the water bath rather than by this thermometer.
Your Alert Profile lists the documents that will be monitored. The Cyclops L-2F Meltmaster portable non-contact thermometer from AMETEK Land offers high-quality castings producer, PSG Foundries, accurate temperature measurement of liquid metal, while providing a much higher level of operator safety and achieving significant savings on consumables.
It is the responsibility of the user of this standard to establish appropriate safety d817 health practices and determine the applicability of regulatory limitations prior to use. The range of the effective density of the chemical in a rubber. Proceed to Checkout Continue Shopping. Insert the stopper, and then remove, dry, and weigh it as described in 9. Calculate the density of the immersion liquid as follows: The density may also be used as a raw material control tool.
ASTM D – 05() – Standard Test Method for Rubber Chemicals. Density
Your comments will receive careful consideration at asfm meeting of the responsible technical committee, which you may attend. Asmt an immersion liquid cannot be found that meets these solubility requirements, 5. The time required for Take care not to decrease the pressure too quickly, otherwise A 5 mass of immersion liquid, and B 5 mass of water, 0. The month of September is a very transitional time of year for most.
Other immersion liquids such as ethylene glycol, tetrahydronaphthalene, etc.
Last previous edition D — 90 e1. If necessary, dry to under the capillary tube than with types having the ground seal on the inside of the neck. Related news Mercury- then and now Nov. Slowly readmit air to the desiccator.
