This International Standard specifies test procedures, conditions and methods according to
which the main parameters and the main operational characteristics of a submerged-arc
furnace (SAF) with rated electrical power levels above 500 kVA are established.
This standard is applicable to SAF with one or more electrodes.
In order to determine further technical or economic assessments, additional tests may be
necessary.
Tests for some special equipment for semiconductor converter controlled furnaces, such as
controlled rectifiers or controlled a.c. converters, are covered by IEC 60146-1-1.
