This standard covers specifications and test methods for unused polybutenes, as delivered, intended for use as insulating liquids in electrical equipment. The requirements given in Sheet 1 are only applicable to unused polybutenes used as an impregnant for paper insulated capacitors and cables and as a filling medium for pipe type cables. NOTE: Polybutenes may be used in transformers, but nowadays this application is not wide enough to justify the development of international specifications. Action could be taken when needed.
