ASTM WK68133
New Test Method for Standard Test Method for Oxidation Induction Time of Natural and Synthetic Ester Electrical Insulating Liquids by Differential Scanning Calorimetry (DSC)
1. Scope
The promotion of knowledge pertaining to electrical insulating liquids and gases, whether of synthetic or natural origin, and the recommendation of standards pertinent to these materials.
The principal materials included in this scope are oils of petroleum origin, synthetic liquids, halogenated and other gases, when used, singularly or as combinations, as electrical insulation or as an environment for electrical insulation.
Standards peculiar to solid insulating materials and varnishes and the development of standards pertaining to the nonelectrical uses of liquid and gaseous materials are excluded from the scope of Committee D27. Development in these fields incidental to the normal work of Committee D27 will be coordinated with the appropriate technical committees of the Society.
Keywords
Differential Scanning Calorimetry (DSC)
Rationale
Presently, ASTM D27 does not have a standard test method to measure the oxidation stability of ester liquids to be considered for use as an electrical insulating liquid in transformers, reactors and switchgear. This standard was in the process of being developed as WK21616,, but lapsed due to excess time to complete the development of the standard. This is the reinstatement preparation.
The title and scope are in draft form and are under development within this ASTM Committee.
