Standard Test Method for Oxidative Aging of Electrical Insulating Liquids by Open-Beaker Method

Importancia y uso:

5.1 Open-beaker oxidative aging methods have been used for many years in laboratories of insulating liquid companies, electrical equipment manufacturers, and electric utility companies interested in the stability of electrical insulating liquids under oxidative conditions. They are particularly useful as a check on the continuity of production and shipment of insulating liquids. They are also useful as process and product checks for applicable type insulating liquids.

5.2 Specification limits for insulating liquids subjected to open-beaker oxidative aging by this method are established by agreement between individual producers and consumers of applicable type insulating liquids. These properties of the insulating liquid involved in specification limits for aging stability may be measured after the oxidative aging (and sometimes before aging) by appropriate test methods such as Test Methods D924, D971, D1169, and D974 or D664. Other test methods such as D445 can be used when deemed appropriate.
