International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 62701:201X
Title Fluids for electrotechnical applications - Recycled mineral insulating oils for transformers and switchgears
Project Number 24216
Abstract/Scope 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.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
