1. Scope

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
