Part 1-2: Guideline on extending IEC 61850

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC


8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

• Subclause 1.2:

In Clause 1, "Scope", a Subclause 1.2 "Published versions of this standard and related

namespace name” shall be added with a table that provides a reference between all IEC

editions, amendments or corrigenda and the full name of the namespace as shown in

Table 10:

If the deliverable includes more than one namespace, additional columns shall be added.

• Subclause 1.3: Identification of the namespaces included in this IEC deliverable

For all the namespaces, the following information shall be provided:

– The nameplate of the namespace with identifier, version, revision and release and

associated code components
– Namespace dependencies

Depending on the namespace technology, additional information may be provided (see for further details related to data model namespaces and to 6.1.7 for XML

• Subclause 1.4 "Code component distribution”

As soon as at least one code component is present in an IEC deliverable, a Subclause 1.4

"Code component distribution" shall be added with some general explanations about code

components and the description of the available code components per namespace (refer to

section 5 of the guidelines document for handling code component as introduced in

Typically this subclause shall start with the following generic explanation about the distribution

of the code component:
"This document is associated with code components.

Each code component is a ZIP package containing at least the electronic representation of the

code component itself and a file describing the content of the package (IECManifest.xml)."

If further versions/revisions may apply, due to some maintenance works, the above shall then

be followed by the following:

publication life cycle goes through two stages, Version (correspond
