IEC 63078-2019 pdf downlaod.Installations for electroheating and electromagnetic processing – Test methods for induction through-heating installations.
This clause of IEC 60398:201 5 is replaced by the following.
This document specifies the test procedures, conditions and methods for determining the main performance parameters and operational characteristics of induction through-heating installations.
Measurements and tests that are solely used for the verification of safety requirements of th installations are outside the scope of this document and are covered by IEC 6051 9-1 and IEC 6051 9-3.
This document is applicable to the induction heating installations which through-heat the whole or part of metal billet or workpiece for its subsequent hot forming (e.g. forging, extruding and rolling), using low, mains or medium frequencies. It is possible to use it as a reference for other induction heating installations for heat-treatment and other purposes as well as superconducting DC induction through-heating installations.
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.
