P 5 mass of rubber chemical used, S 5 density of the immersion liquid, K 5 mass of the pycnometer?
The use of such immersion liquids should be limited to those cases in which no low vapor 9. Thoroughly dry the outside of the pycnometer and weigh. B mass of water, 3 0. When no more bubbles can be seen, it may be assumed that occluded Originally published as D — 61 T. It is an essential part of maintaining high-quality glass production and extending the campaign life of a furnace 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.
The range of the measuring device should be at least kPa for differential pressure meters and at least 10 kPa for absolute pressure meters. 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.
When no more bubbles can be seen, it may be assumed that occluded air has been removed and the rubber chemical is thoroughly wet with immersion liquid. Standardization of Pycnometer 9. The month of September is a very transitional time of year for most.
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.
Precision and Bias The pressure meter is used to indicate whether the oil pump is giving the proper vacuum, which is an absolute pressure of 0.
ASTM De1 – Standard Test Method for Rubber Chemicals&#;Density
Weigh rubber chemicals of a hygroscopic nature from a weighing bottle. A 5 mass of immersion liquid, and B 5 mass of water, 0.
Summary of Test Method 3. 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. Last previous edition D — 90 e1. That is not always an easy task, but there is a method The pressure meter is used to indicate whether If the document is revised aatm amended, you will be notified by email.
Kids are back in school, summer lingers on, while fall gradually appears. This test method covers the determination of the density of solid chemicals used as rubber additives during processing and manufacture. 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.
A pinch-cock may be used to control asgm rate of evacuation. Grind any lumps, pellets, etc. Apparatus of powders that require no further treatment. When necessary, swirl the contents of the pycnometer by hand, to wet the sample. Need more than one copy? Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The desiccator should be enclosed in a sturdy box or shield to prevent possible injury to the operator.
The density may also be used as a raw material control tool. Place the pycnometer the pycnometer, then clean, dry, and reweigh it. The use of such immersion liquids should be limited to those cases in which no low vapor However, the control of the temperature is through the adjustment of the water bath rather than by this thermometer.
Dip the pycnometer up to the side arm in a beaker of alcohol to remove any residual immersion liquid. Last previous edition D — 90 1. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
