The degree of crosslinking is not expressed as a percent of total crosslinkability or similar expression, but is judged from swell ratio and percent extract based on experience with the particular polymer-solvent system under consideration. NOTE 7—The solvent must cover the swollen test specimen at the conclusion of the immersion period to obtain reliable results. The inch-pound units in brackets are for information only. The methods described herein are applicable to crosslinked ethylene plastics of all densities, including those containing fillers, and all provide corrections for the inert fillers present in some of those compounds. Tests shall be discarded and repeated with a fresh test specimen if specimens are not covered with solvent at the conclusion of the extraction step.

Ast over the open side of the pouch and staple the edge to form a cage. NOTE 9—The size of the swollen test specimen dictates the size of the weighing bottle to be used.
Determination of Gel Content and Swell Ratio of Crosslinked Ethylene Plastics
Extraction tests permit verification of the proper gel content of any given crosslinked ethylene plastic and they also permit comparison between different crosslinked ethylene plastics, including those containing fillers, atsm that, for the latter, the following axtm are met: A bench-top laboratory mill4,5 is satisfactory, although any procedure which will produce a sample of the required?
