1 Scope and object This clause of Part 1 is replaced by the following.
Replacement:
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 material to be treated. 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 60519‑1:2010 defines infrared as radiation within the frequency range between about 400 THz and 300 GHz. This corresponds to the wavelength range between 780 nm and 1 mm in vacuum. Industrial infrared heating usually uses 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 e.g. blackbody thermal emitters may extend beyond 780 nm or 3 000 nm, the safety aspects of emitted visible light and emission at wavelengths longer than 3 000 nm are also considered in this standard. This standard is not applicable to:
