  • ICEA T-28-562, 3rd Edition, May 10, 2004 - TEST METHOD FOR MEASUREMENT OF HOT CREEP OF POLYMERIC INSULATIONS

    This test method provides a procedure, which is suited fordetermining the relative degree of crosslinking of polymeric,electric cable insulations.

    Summary of Method:

    Elongation Test: A specimen is subjected to a constant loadstress while suspended in an air oven at a specified elevatedtemperature for a specified time period. At the end of the timeperiod the increase in elongation of the specimen isdetermined.

    Set Test: Immediately after the elongation test has beencompleted on a specimen, the same specimen with the load stressremoved, will be subjected to an additional time period in the ovenat the same elevated temperature. The specimen is then removed andallowed to cool. The set of the specimen, based on original length,is then determined.

    Significance:

    The test method has a consistent reproducibility, which makes itparticularly suitable as a quality control test for determiningrelative degree of crosslinking. This method has been found morereproducible than the other methods in current use such as heatdeformation. Also, it corresponds more closely to serviceconditions than a solvent-extraction procedure.
