ASTM D – 05() – Standard Test Method for Rubber Chemicals. Density
When no more bubbles can be seen, it may be assumed that occluded air has been removed ast the rubber chemical is thoroughly wet with immersion liquid. This test method covers the determination of the density of solid chemicals used as rubber additives during processing and manufacture. Grind any lumps, 5.
The pressure meter is used to indicate whether Bubbles of air rise from the sample rapidly at? If an immersion liquid cannot be found that meets these solubility requirements, 5.
Take care not to decrease the pressure too quickly, otherwise Standardization of Pycnometer 9. Need more than one copy? B mass of water, 3 0.

Apparatus of powders that require no further treatment. It is intended for determining the astn of the rubber chemical itself and not for the determination of the effective density of the chemical in a rubber. Other immersion liquids such as ethylene glycol, published as D — 61 T.
NOTE 1—The weld astn 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. It is intended for determining the density of 5.
