IEC 62701:2014

IEC 62701:2014 specifies requirements for recycled mineral insulating oils intended for use in transformers, switchgear, and similar electrical equipment in which oil is required for insulation and heat transfer. These oils are produced by processes employed offsite. Oils treated and reconditioned on-site are not within the scope of this standard. Oils with and without additives are within the scope of this standard. Such oils will have originally been supplied in compliance with a recognized unused mineral insulating oil specification. This standard does not differentiate between the methods used to recycle mineral insulating oil. This standard does not apply to mineral insulating oils used as impregnates in cables or capacitors.
