scope:

This part of IEC 60519 specifies safety requirements for industrial electroheating equipment and installations in which infrared radiation - usually generated by infrared emitters - is significantly dominating over heat convection or heat conduction as means of energy transfer to the workload. A further limitation of the scope is that the infrared emitters have a maximum spectral emission at longer wavelengths than 780 nm in air or vacuum, and are emitting wideband continuous spectra such as by thermal radiation or high pressure arcs.

IEC 60519-1:2015 defines infrared as radiation within the frequency range between 400 THz and 300 GHz. This corresponds to a wavelength range between 780 nm and 10 μm in vacuum. Industrial infrared heating commonly uses thermal infrared sources with rated temperatures between 500 °C and 3 000 °C; the emitted radiation from these sources dominates in the wavelength range between 780 nm and 10 μm.

Since substantial emission of thermal emitters can extend either to wavelengths below 780 nm or above 3 000 nm, the safety aspects of emitted visible light and emission at wavelengths longer than 3 000 nm are also considered in this document.
