- terms/definitions, normative references and bibliography have been updated and completed;
- Clause 4 on classification of equipment according to process frequency has been modified;
- Clause 5 (General requirements) has been redrafted and new provisions have been added (e.g. relating to single fault conditions and EMF issues), following the recommendations of IEC Guide 104;
- Clause 8 has been redrafted, the contents of subclauses 8.2 and 8.3 has been moved to a new normative Annex A and 8.4 has been deleted;
- a new Clause 12 (Protection against other hazards) has been added;
- clauses dealing with marking and documentation have been amended.
The French version of this standard has not been voted upon. The contents of the corrigendum of November 2012 have been included in this copy.

SAFETY IN ELECTROHEATING INSTALLATIONS –
Part 1: General requirements
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
