Fluids for electrotechnical applications – Mineral insulating oils for electrical equipment
IEC 60296:2020 provides specifications and test methods for unused and recycled mineral insulating oils. It applies to mineral oil delivered according to the contractual agreement, intended for use in transformers, switchgear and similar electrical equipment in which oil is required for insulation and heat transfer. Both unused oil and recycled oil under the scope of this document have not been…
Energy management system application program interface (EMS-API) - Part 301: Common information mode...
IEC 61970-301:2020 lays down the common information model (CIM), which is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of network applications…
Fibre optic interconnecting devices and passive components - Performance standard - Part 1: General ...
IEC 61753-1:2018+A1:2020 provides guidance for the drafting of performance standards for all passive fibre optic products. This document defines the tests and severities which form the performance categories or general operating service environments and identifies those tests which are considered to be product specific. Test and severity details are given in Annex A. This second edition cancels…
Information technology - MPEG audio technologies - Part 3: Unified speech and audio coding
This document specifies a unified speech and audio codec which is capable of coding signals having an arbitrary mix of speech and audio content. The codec has a performance comparable to, or better than, the best known coding technology that might be tailored specifically to coding of either speech or general audio content. The codec supports single and multi-channel coding at high bitrates and…
Standardized product ontology register and transfer by data parcels - Part 8: Web service interface ...
IEC 62656-8:2020 specifies a web service interface to exchange data parcel(s) conformant to IEC 62656-1, between a parcel server and a parcel client or between parcel servers. This interface comprises three basic services: a registration service, resolution service and subscription service.
This document includes the following:
– holistic use scenario;
– detailed specification of the three basic…

Determination of certain substances in electrotechnical products - Part 10: Polycyclic aromatic hydr...
IEC 62321-10:2020 specifies one normative technique for the determination of polycyclic aromatic hydrocarbons (PAHs) in polymers of electrotechnical products. These PAHs can especially be found in the plastic and rubber parts of a wide range of consumer articles. They are present as impurities in some of the raw materials used in the production of such articles, in particular in extender oils and…
