    Abstract - (Show below) - (Hide below)

    Covers specifications and test methods for unused mineral insulating oils.

    Scope - (Show below) - (Hide below)

    This International Standard is applicable to specifications and test methods for unused mineral insulating oils (see Clause 3 for definitions). 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.

    NOTE Definitions and specifications for recycled oils will be covered by IEC 627011.

    This standard does not apply to mineral insulating oils used as impregnants in cables or capacitors.
