IEC 60703:2008 lays down the test methods to determine the essential parameters, technical data and characteristics of electroheating installations comprising one or more electron guns. The significant changes with respect to the previous edition are as follows: the latest edition of IEC 60519-7 has been taken into account; test requirements have been completed.
