standards conflicting with the
document have to be withdrawn
The clauses of parts of the EN 60519 series (hereinafter called Particular requirements) supplement or
modify the corresponding clauses of EN 60519-1:2011 (General requirements hereinafter called Part 1).

This part of EN 60519 is to be read in conjunction with Part 1. It supplements or modifies the
corresponding clauses of Part 1. Where the text indicates an "addition" to or a "replacement" of the
relevant provision of Part 1, these changes are made to the relevant text of Part 1. Where no change is
necessary, the words "This clause of Part 1 is applicable" are used. When a particular subclause of Part 1
is not mentioned in this part, that subclause applies as far as is reasonable.

Additional specific provisions to those in Part 1, given as individual clauses or subclauses, are numbered
starting from 101.
NOTE The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced
clause or subclause;
– additional annexes are lettered AA, BB, etc.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent
rights.
This standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed

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 re
