Overview
IEC 62693:2013 is an international standard developed by the International Electrotechnical Commission (IEC) that defines test methods for industrial infrared electroheating installations. It specifies procedures, test conditions, and measurement techniques to establish main operating parameters and performance characteristics of these installations. The standard is applicable to industrial infrared electroheating systems where infrared emitters produce maximum spectral emissions longer than 780 nm, using wideband continuous spectra such as thermal radiation or high-pressure arcs.
This standard supports manufacturers, engineers, and users in assessing and optimizing the efficiency, energy consumption, and operational effectiveness of industrial infrared electroheating installations. It targets installations where infrared radiation is the dominant heat transfer mechanism, typically generated by Joule effect in various types of infrared emitters.
