Foreword

The text of document 108/135A/FDIS, future edition 2 of IEC 60950-1, prepared by IEC TC 108, Safety of

electronic equipment within the field of audio/video, information technology and communication

technology, was submitted to the IEC-CENELEC parallel.

This text, together with a draft amendment, prepared by the Technical Committee CENELEC TC 108,

Safety of electronic equipment within the fields of audio/video, information technology and communication

technology, and submitted to the formal vote, was approved by CENELEC as EN 60950-1 on 2005-12-01.

This European Standard supersedes EN 60950-1:2001 + corrigendum April 2004 + A11:2004.

EN 60950-1 includes the basic requirements for the safety of information technology equipment.

Additional parts of EN 60950-1 will cover specific safety requirements for information technology

equipment having limited applications or having special features as follows:
Part 21: Remote power feeding;
Part 22: Equipment installed outdoors;
Part 23: Large data storage equipment.

Except for notes, all text within a normative figure, or in a box under a normative table, is also normative.

Text with a superscript reference is linked to a particular item in the table. Other text in a box under a table

applies to the whole table.

Informative annexes and text beginning with the word "NOTE" are not normative. They are provided only

to give additional information.
In this standard, the following print types are used:
− Requirements proper and normative annexes: roman type.
− Compliance statements and test specifications: italic type.
− Notes in the text and in tables: smaller roman type.
− Terms that are defined in 1.2: SMALL CAPITALS.
The following dates were fixed:
− latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2006-12-01
national standard or by endorsement
− latest date by which the national standards conflicting
(dow) 2010-12-01
with the EN have to be withdrawn

Clauses, subclauses, notes, tables and figures which are additional to those in IEC 60950-1 are prefixed

Annex ZB
(normative)
Special national conditions

Special national condition: National characteristic or practice that cannot be changed even over a long

period, e.g. climatic conditions, electrical earthing conditions.

NOTE If it affects harmonization, it forms part of the European Standard / Harmonization Document.

For the countries in which the relevant special national conditions apply these provisions are normative,

for other countries they are informative.
Clause Special national condition
1.2.4.1

In Denmark, certain types of Class I appliances (see 3.2.1.1) may be provided with a plug

not establishing earthing conditions when inserted into Danish socket-outlets.

1.5.7.1 In Finland, Norway and Sweden, resistors bridging BASIC INSULATION in CLASS I PLUGGABLE

EQUIPMENT TYPE A must comply with the requirements in 1.5.7.2.

1.5.8 In Norway, due to the IT power system used (see annex V, Figure V.7), capacitors are

required to be rated for the applicable line-to-line voltage (230 V).
1.5.9.4

In Finland, Norway and Sweden, the third dashed sentence is applicable only to equipment

as defined in 6.1.2.2 of this annex.

below, or

- one layer having a distance through insulation of at least 0,4 mm, which shall pass the

electric strength test below.

If this insulation forms part of a semiconductor component (e.g. an optocoupler), there is no

distance through insulation requirement for the insulation consisting of an insulating

compound completely filling the casing, so that CLEARANCES and CREEPAGE DISTANCES do

not exist, if the component passes the electric strength test in accordance with the

compliance clause below and in addition
