ASTM.D Determination of Gel content and swell ratio of crosslinked ethylene plastics_百度文库

Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. Weigh this pouch W1. L—mesh wire cage ast, the specimen. Test specimens that break up during the immersion period usually very low degrees of crosslinking can be caught on a mesh or? The outer sections of this strip are discarded, thus leaving only a sample of the material closest to the conductor or shielded surface.

Any test specimen preparation, conditioning, dimensions, or testing parameters, or a combination thereof, covered in the materials specification shall take precedence over those mentioned in this test method.

The test specimen should not be squeezed with the forceps. Fold two sides of this square closed by folding the cloth at the edges about r2765 to 7 mm [1? NOTE 7—The solvent must cover the swollen test specimen at the conclusion of the immersion period to obtain reliable results.

Stopper the weighing bottle. If necessary, place a weight on the jar or clamp it to hold it in place. NOTE 5—If the modi? Such extraction test methods are described herein. Specific precautionary statements are given in Sections 69and The test strip used for extraction should be asym next to the conductor only when strand shielding tapes or compounds are not employed.

If there are no material specifications, then the default conditions apply. Hence, determination of the gel content provides a means of both controlling the process and rating the quality of? Glass wool 13 to 19 mm thick [1?
