IEC 60779:2020规定了确定电渣重熔炉主要性能参数和操作特性的试验程序、条件和方法。 仅用于验证装置安全要求的测量和试验超出了本文件的范围，由IEC 60519-1和IEC 60519-8涵盖。 这第三版取消并取代了2005年出版的第二版。它构成技术修订。 与上一版相比，此版本包括以下重大技术变更: -结构已根据IEC 60398:2015重新起草； -重新起草了范围和目标； -术语/定义、规范性参考文献和参考书目已经更新和完成； -已删除IEC 60398:2015中包含的IEC 60779:2005中的所有测试方法和内容，以避免任何重复。

IEC 60779:2020 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 third edition cancels and replaces the second edition published in 2005. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- the structure has been redrafted according to IEC 60398:2015;
- the scope and object have been redrafted;
- the terms/definitions, normative references and bibliography have been updated and completed;
- all test methods and content from IEC 60779:2005 that have been included in IEC 60398:2015 have been removed to avoid any duplication.
