Overview

This International Standard shall be applied to requirements and test methods for unused mineral insulating oils. It applies to oil delivered to the agreed point and time of delivery, intended for use in transformers, switchgear and similar electrical equipment in which oil is required for insulation and heat transfer. These oils are obtained by refining, modifying and/or blending of petroleum products and other hydrocarbons. Oils with and without additives are both within the scope of this standard. This standard is applicable only to unused mineral insulating oils. Recycled oils are beyond the scope of this standard. Terms and definitions and specifications for recycled oils will be covered by IEC 62701 (in preparation). This standard does not apply to mineral insulating oils used as impregnants in cables or capacitors. Mineral insulating oils complying with the requirements of this standard, of the same class and containing no additives, are considered to be compatible with one another and can be mixed in any proportion. This does not apply to oils containing additives. This International Standard does not purport to address all the safety problems associated with its use. It is the responsibility of the user of the standard to establish appropriate health and safety practices and determine the applicability of regulatory limitations prior to use. The mineral insulating oils which are the subject of this standard should be handled with due regard to personal hygiene. Direct contact with the eyes may cause irritation. In the case of eye contact, irrigation with copious quantities of clean running water should be carried out and medical advice sought. Some of the tests described in this standard involve the use of processes that could lead to a hazardous situation. Attention is drawn to the relevant standard for guidance. This standard is applicable to mineral insulating oils, chemicals and used sample containers. The disposal of these items should be carried out according to local regulations with regard to their impact on the environment. Every precaution should be taken to prevent release of mineral insulating oil into the environment. For Austria, special national conditions were set because of the exposed geographical location and cold weather conditions (snow) transformers are not always accessible for service, which sometimes leads to unforeseen longer service intervals. Therefore higher oxidation stability of transformer oil is required. The responsible committee is DKE/K 182 "Flüssigkeiten und Gase für elektrotechnische Anwendung" ("Fluids and gases for electrotechnical applications") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
