18、ii Scope This test method provides a procedure, which is suited for determining the relative degree of crosslinking of polymeric, electric cable insulations. Summary of Method: Elongation Test: A specimen is subjected to a constant load stress while suspended in an air oven at a specified elevated t
19、emperature for a specified time period. At the end of the time period the increase in elongation of the specimen is determined. Set Test: Immediately after the elongation test has been completed on a specimen, the same specimen with the load stress removed, will be subjected to an additional time pe
20、riod in the oven at the same elevated temperature. The specimen is then removed and allowed to cool. The set of the specimen, based on original length, is then determined. Significance: The test method has a consistent reproducibility, which makes it particularly suitable as a quality control test f
