IEC 60519-12:20 16规定了工业电加热设备和装置的安全要求，在这些设备和装置中，红外辐射（通常由红外发射器产生）作为向工作负载传递能量的手段明显超过热对流或热传导。范围的进一步限制是红外发射器在空气或真空中在比780nm更长的波长处具有最大光谱发射，并且发射宽带连续光谱，例如通过热辐射或高压电弧。这第二版取消并取代了2013年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更: a.结构已按IEC 60519-1:2015; b.术语/定义、规范性参考文献和参考书目已经更新和完成； c.删除了IEC 60519-1:20 15中包含的IEC 60519-12:20 13中的所有要求和内容，以避免任何重复。

IEC 60519-12:2016 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. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a. the structure has been redrafted according to IEC 60519-1:2015;
b. terms/definitions, normative references and bibliography have been updated and completed;
c. all requirements and content from IEC 60519-12:2013 that have been included in IEC 60519-1:2015 have been removed to avoid any duplication.
