Clause 1 of IEC 60398:2015 is replaced by the following.
Replacement:
This International Standard specifies the test procedures, conditions and methods for determining the main performance parameters and operational characteristics of electroslag remelting furnaces.
Measurements and tests that are solely used for the verification of safety requirements of the installations are outside the scope of this document and are covered by IEC 60519-1 and IEC 60519-8.
This document applies to industrial electroslag remelting furnaces, the rated capacity of which is equal to, or greater than, 50 kg.
This document is applicable to industrial electroslag remelting furnaces having one or more electrodes and having different melting power supplies, such as alternating current, direct current, or low-frequency current.
This document includes the concept and material on energy efficiency dealing with the electrical and processing parts of the installations, as well as the overall performance.
