1 Scope and object
This clause of Part 1 is replaced by the following.
Replacement:
This part of IEC 60519 provides particular safety requirements for electric arc furnace installations and
its operating and maintenance personnel.
These safety provisions concern the protection of persons and the environment against
dangers of electrical origin and also against certain dangers of non-electrical origin.
This standard is applicable to electroheating installations such as:
-
a) Furnaces for direct arc heating, forming arcs between the electrode and metal such
as the electric arc furnace using alternating current (EAFac) or direct current (EAFdc),
and ladle furnace (LF);
-
b) Furnaces for arc-resistance heating forming arcs between the electrode and the charge
material or heating the charge material by the Joule effect, such as the submerged
arc furnace using alternating current (SAFac), or direct current (SAFdc).
NOTE For purposes of this document abbreviation EAF is used for all kinds of electric arc
furnace installations.
