IEC TR 62471-2 pdf download Photobiological safety of lamps and lamp systems – Part 2: Guidance on manufacturing requirements relating to non-laser optical radiation safety
1 Scope
This technical report provides the basis for optical radiation safety requirements of non-laser products, serving as a guide for development of safety requirements in vertical product standards and assisting lamp system manufacturers in the interpretation of safety information provided by the lamp manufacturers.
This report provides guidance on:
• requirements for optical radiation safety assessment;
• allocation of safety measures;
• labelling of products.
This technical report does not address safety requirements of intentional exposure to optical radiation from sun tanning equipment, ophthalmic instruments or other medical/cosmetic devices whose specific safety issues are addressed through appropriate standards.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
IEC 62471 , Photobiological safety of lamps and lamp systems

3 Terms and definitions
For the purposes of this document, the terms and definitions of IEC 62471 and the following additional terms and definitions apply.
controlled access location
location where an engineering and/or administrative control measure is established to restrict access except to authorised personnel with appropriate safety training
exposure hazard value
value defined as follows:
The EHV is greater than 1 when the exposure level (3.3) exceeds the exposure limit value (3.4)
exposure level
level of exposure from a source at a location in space for a stated duration
exposure limit value
maximum level of exposure of optical radiation to the eye or skin that is not expected to result in adverse biological effects. These ELVs are used to determine hazard distances in respect
to foreseeable photobiological effects
hazard distance
distance from the source at which the EL equals the appropriate exposure limit value (ELV)
intended viewing
deliberate act of an individual to either look at a source of optical radiation or at a virtual source, such as a reflection
intended use
usage of a product, process or service in accordance with specifications, instructions and information provided by the manufacturer or supplier
electrically powered device emitting optical radiation in the wavelength range between 200 nm and 3 000 nm, with the exception of laser radiation
lamp system
electrically operated product incorporating a lamp or lamps, including fixtures and incorporated electrical or electronic components, generally as intended by the manufacturer to be used (for illumination purposes – luminaire)
NOTE 1 Lamp systems may include diffusers, enclosures and/or beam modifying optics.
