Standard Test Method for Oxidative Aging of Electrical Insulating Petroleum Oils by Open-Beaker Method
 N D1934

Annotation

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

Procedure A, without a metal catalyst, and

Procedure B, with a metal catalyst.

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.

The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

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.
