Foreword
The text of the International Standard IEC 60204-1:2005, prepared by IEC TC 44, Safety of machinery –
Electrotechnical aspects, together with common modifications prepared by the Technical Committee
CENELEC TC 44X, Safety of machinery – Electrotechnical aspects, was approved by CENELEC as
EN 60204-1 on 2006-06-01.
This European Standard supersedes EN 60204-1:1997.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-06-01
NOTE The application of this standard can involve the selection of components and/or parts that are to be integrated with the
electrical equipment of a machine in accordance with the instructions and/or specifications of the manufacturers of the components
and/or parts.
Also, in the context of legislative duties that are applicable to machinery manufacturers within the European Union it is important to
recognise that the safety of electrical equipment can involve the use of equipment and services provided by other parties (see 3.54).
To assist manufacturers in satisfying these duties it can be necessary for the supplier of the equipment to obtain information about
its intended use. This can be facilitated by establishing an agreement between the user and supplier on basic conditions and
additional user requirements to enable proper design, application and utilization of the electrical equipment of the machine. An
enquiry form that can be used for this purpose is provided in Annex B. Such an agreement is not intended to reduce the level of
safety of the electrical equipment provided by this standard.

SIST EN 60204 : 2006
NACIONALNI UVOD
Slovenski standard SIST EN 60204-1 (sl), Varnost strojev – Električna oprema strojev – 1. del:
Splošne zahteve, 2006, ima status slovenskega standarda in je istoveten standardu EN 60204-1 (en),
Safety of machinery – Electrical equipment of machines – Part 1: General requirements (en), 2006.
Ta slovenski standard nadomešča SIST EN 60204-1:1999.
Ta standard vključuje popravek AC iz februarja 2010.
NACIONALNI PREDGOVOR
Standard EN 60204-1:2006 je pripravil tehnični odbor Evropskega komiteja za standardizacijo v
elektrotehniki CENELEC/TC 44X Varnost strojev – elektrotehniški vidiki.
Slovenski standard SIST EN 60204-1:2006 je prevod angleškega besedila evropskega standarda EN
60204-1:2006. V primeru spora glede besedila slovenskega prevoda v tem standardu je odločilno
izvirno besedilo evropskega standarda v angleškem jeziku. Slovensko izdajo tega standarda je
pripravil tehnični odbor SIST/TC MOV Merilna oprema za elektromagnetne veličine.
Odločitev za prevzem tega standarda je 15. septembra 2005 sprejel tehnični odbor SIST/TC MOV
Merilna oprema za elektromagnetne veličine.
