IEC 60519-8:2020 specifies particular safety requirements for electroslag remelting equipment and installations.
This document specifies safety requirements applicable to mainly electroheating installations for remelting and, in some cases, for refining processes of metals through direct resistance heating of a conductive slag.
The object of this document is to specify the particular requirements for the safety of persons in or around an electroslag remelting furnace. The general requirements are included in IEC 60519-1.
This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the structure has been redrafted according to IEC 60519-1:2020;
b) the Scope has been redrafted;
c) the terms and definitions, normative references and bibliography have been updated and completed;
d) all requirements and content from IEC 60519-8:2005 that have been included in IEC 60519？1:2020 have been removed to avoid any duplication.
