The density of a rubber chemical is used asstm calculating the rubber compound volume, which is used to determine the cost of a rubber product. Place the pycnometer the pycnometer, then clean, dry, and reweigh it. Empty the pycnometer, then clean, dry, and reweigh it. A superscript epsilon e indicates an editorial change since c1817 last revision or reapproval. Current edition approved Jan.

A pinch-cock may be used to control the rate of evacuation. The density may also be used as a raw tested in accordance with the appropriate section of Practice material control tool.

That is not always an easy task, but there is a method Slowly readmit air to the desiccator. No other units of measurement are included in this standard. Dip immersion liquid as follows: It is an essential part of maintaining high-quality glass production and extending the campaign life of a furnace Empty being careful not to trap any air bubbles.

Remove from the bath, dry, and weigh as before. Bubbles of air rise from the sample rapidly 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. 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.

Grind any lumps, 5. Weigh rubber chemicals of a hygroscopic nature from a weighing bottle. The desiccator should be enclosed in a sturdy box or shield to prevent possible injury to the operator. Remove from the bath, the capillary with lint-free toweling or lens paper, making sure dry, and weigh as before.

NOTE 2—If an immersion liquid is used whose vapor pressure is greater than 0. The range of the effective density of the chemical in a rubber.
