This specification provides the limits within which the properties of electrical insulating polybutene oil for capacitors shall conform to ensure an unvarying continuity in the quality and grade of polybutene oil supplied. The oil shall conform to the prescribed physical, chemical, and electrical requirements, and shall be subject to aging test.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification provides the limits within which the properties of electrical insulating polybutene oil for capacitors shall conform in order to ensure an unvarying continuity in the quality and grade of polybutene oil supplied.
1.2 It is expected that additional laboratory or service tests of the purchaser's own choosing may be applied to polybutene oil from each source of supply before approval for use.
