Safety in electroheating installations.Part 1: General requirements

2Scope / Description

This part of IEC 60519 specifies the general safety requirements applicable to industrial
electroheating installations.
In case these requirements differ from those of other IEC publications, an equivalent
degree of safety is ensured.
The requirements apply to industrial installations, intended for electroheating and
electroheat based treatment technologies, with the possible use of the following equipment:
– equipment for direct and indirect resistance heating;
– equipment for electric resistance trace heating;
– equipment for induction heating;
– equipment using the effect of EM forces on liquid metals;
– equipment for arc heating, including submerged arc heating;
– equipment for electroslag remelting;
– equipment for plasma heating;
– equipment for microwave heating;
– equipment for dielectric heating;
– equipment for electron beam heating;
– equipment for laser heating;
– equipment for infrared radiation heating.
This standard is not applicable for heating appliances for household (e.g. electric cooking),
laboratory or medical applications or for welding equipment, if covered by other particular
standards, nor does it apply to any kind of space heating.
This standard refers to normal operation of industrial electroheating installations. It is
intended to ensure the safety of persons also in the case of abnormal operation and when
faults occur in electroheating installations. This standard presumes that the installations are
operated and maintained only by personnel consisting of instructed or skilled persons,
respectively.
The object of this standard is to specify the general safety requirements for electroheating
installations. These safety requirements concern the protection of persons and the
environment against dangers of electrical origin and also against certain dangers of nonelectrical
origin, common to all types of equipment and installations.
