This part of IEC 60519 is applicable to equipment using high frequency or microwave energy alone or in combination with other kinds of energy for industrial heating and processing of materials. It is also applicable to HF and MW generators made available to users as separate units.
This part is applicable to equipment operating in the frequency range 3 MHz to 300 GHz, with the following limitations.
- This document applies to only high frequency dielectric heating and processing as defined in 3.1.103. It does not apply to induction heating, which it is possible to carry out in the lower part of the specified frequency band and is covered by IEC 60519-3, with magnetic field safety aspects addressed in IEC TS 62997:2017, the latter to be replaced by a technical report (TR) or by a revised technical specification (TS).
- The ISM centre frequencies for dielectric heating and processing of industrial interest are narrow bands about 6,78 MHz, 13,56 MHz, 27,12 MHz and 40,68 MHz. Different field emission measurement procedures and limiting values are applicable, depending on the processing frequency in the high frequency range 3 to 300 MHz. Specifications are in Annex BB.
- This document specifies limits for microwave emission only for the ISM frequencies between 800 MHz and 6 MHz, as specified in Annex CC. For other microwave frequencies the basic restriction and IEC 62311 apply.
- The foundations for compliance with emission values are the basic restrictions, referred to in the IEEE/ANSI C95.1:2019 and Directive 2013/35/EU. However, maximum HF processing frequency electric and magnetic field values are taken from the IEEE/ANSI C95.1:2019 standard, as indicated in Annex BB.
- This document is not applicable to:
-- appliances for household and similar use (covered by e.g. IEC 60335-2-25);
-- commercial use (covered by IEC 60335-2-90 and IEC 60335-2-110);
-- laboratory use (covered by IEC 61010-2-010);
-- medical high frequency equipment and accessories (covered by IEC 60601-2-2).
NOTE 101 Since high frequency and microwave tunnel ovens and also some other types of microwave and high frequency equipment are sometimes intended either for commercial, laboratory or industrial use, the following criteria are suitable for determination of the classification as industrial equipment:
- commercial equipment is typically designed and planned for series production of many identical units, whereas industrial equipment is typically produced in small series or even as single units. The processed goods are consumed or ready for final use at the end of the heating process.
- laboratory heating equipment is for preparing material in a laboratory environment, and the processed material is immediately available for investigations or further processing. Regular production of large quantities of material is not foreseen.
- with industrial equipment, the processed goods are not immediately accessible to the end user, and the goods are sometimes not in a final state from the perspective of the end user.

This part of IEC 60519 provides particular safety requirements for arc furnace installations. This document deals with the significant hazards, hazardous situations or hazardous events relevant to industrial arc furnace installations, as listed in Annex A, for normal operation and for single fault condition as well as under conditions of reasonably foreseeable misuse.
This document specifies the requirements intended to be met by the manufacturer to ensure the safety of persons and property during the complete life cycle of the equipment from design through commissioning, operation, maintenance, inspection, to decommissioning, as well as in the event of foreseeable single fault condition that can occur in the equipment.
The rated voltage of arc furnace installation can be in the range of low voltage or high voltage, details are given in 4.2.
This standard is applicable to arc furnace installations such as:
a) furnaces for direct arc heating, forming arcs between the electrode and metal such as the electric arc furnace using alternating current (EAF AC) or direct current (EAF DC), and the ladle furnace (LF);
b) furnaces for arc-resistance heating forming arcs between the electrode and the charge material or heating the charge material by the Joule effect, such as the submerged arc resistance furnace using alternating current (SAF AC), or direct current (SAF DC).
NOTE In some documents the terms smelter or electrical reduction furnace are used.
Furnace installation for unattended operation is not covered by this standard.
This document does not provide requirements for type testing.
NOTE Industrial equipment covered by this document is typically produced as a single unit or a very small number of units; such unit usually has a very high value and can cause severe harm at disintegration.
This document does not address data security and hazards arising from neglect of security.
With respect to noise of electrical an arc furnace, ISO 13578:2017, 6.1.23 applies.
