ASTM D1934-95(2000) PDF

1.1 This test method describes two procedures for subjecting electrical insulating oils to oxidative aging:

1.1.1 Procedure A , without a metal catalyst, and

1.1.2 Procedure B , with a metal catalyst.

1.2 This test method is applicable to oils used as impregnating or pressure media in electrical power transmission cables if less than 10% of the oil evaporates during the aging procedures. It applies and is generally useful primarily in the evaluation and quality control of unused oils, either inhibited or uninhibited.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
