National foreword

This British Standard is the UK implementation of

EN 60950-1:2006+A1:2010, incorporating A11:2009. It is derived from

IEC 60950-1:2005, incorporating amendment 1:2009. It supersedes

BS EN 60950-1:2001, which will be withdrawn on 1 March 2013, and

BS EN 60950-1:2006 which is withdrawn.

The CENELEC common modifications have been implemented at the

appropriate places in the text and are indicated by tags (e.g. }~).

Where a common modification has been introduced by amendment, the

tags carry the number of the amendment. For example, the common

modifications introduced by CENELEC amendment A11 are indicated

by hi.

Where a common modification to an IEC amendment has been intro-

duced, the tags carry the number of the amendment. For example, the

common modifications introduced by CENELEC to IEC amendment 1

are indicated by PQ.

The start and finish of text introduced or altered by amendment is in-

dicated in the text by tags. Tags indicating changes to IEC text carry

the number of the IEC amendment. For example, text altered by IEC

amendment 1 is indicated by !".

The UK participation in its preparation was entrusted to Technical

Committee EPL/108, Safety of electronic equipment within the field of

audio/video, information technology and communication technology.

A list of organizations represented on this committee can be obtained

on request to its secretary.

This publication does not purport to include all the necessary

provisions of a contract. Users are responsible for its correct

application.

Compliance with a British Standard cannot confer immunity

from legal obligations.

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.
