Foreword
The text of document 48B/1892/FDIS, future edition 1 of IEC 60512-26-100, prepared by SC 48B,
Connectors, of IEC TC 48, Electromechanical components and mechanical structures for electronic
equipment, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60512-26-100 on 2008-10-01.
This European Standard cancels and replaces the annexes of EN 60603-7-x documents dealing with
transmission characteristics for interoperability and backward compatibility.
This standard is to be read in conjunction with EN 60512-1 and EN 60512-1-100 which explains the
structure of the EN 60512 series.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2009-07-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2011-10-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60512-26-100:2008 was approved by CENELEC as a
European Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60068-1 NOTE  Harmonized as EN 60068-1:1994 (not modified).
IEC 60512-25 NOTE  Harmonized in EN 60512-25 series (not modified).

FOREWORD
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 regiona
