Photobiological safety of lamps and lamp systems - Part 2.

Guidance on manufacturing requirements relating to non-

laser optical radiation safety

1 Scope

This part of GB/T 30117 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.

2 Normative references

The following documents are essential to the application of this document. For the dated

referenced documents, only the versions with the indicated dates are applicable to this

document; for the undated referenced documents, only the latest version (including all

the amendments) is applicable to this document.

IEC 62471 Photobiological safety of lamps and lamp systems

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

The 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.

Risk for intended or unintended viewers of a source under application-specific realistic

conditions.

4 Risk groups applied for optical radiation safety assessments

There may be a small number of applications where an incoherent optical radiation

source appears as a nearly monochromatic "point" source and shall be considered within

a laser safety standard framework. Generally, this will only apply to super luminescent

diodes (SLDs) (see 3.16), which resemble "point sources"; and LEDs which are

employed in optical fiber communications, where the fiber source also resembles a very

small, or "point" source.

5 Guidelines for lamp and lamp system manufacturers on how to apply IEC 62471

In the spectral ranges 200 nm to 400 nm and 1400 nm to 3000 nm where the emission

limits in IEC 62471 are provided in irradiance or radiant exposure, the measurements

of a single lamp cannot simply be transferred directly to a lamp system but require an

analysis of the optical additivity to determine the system risk group.

6 Allocation of safety measures

Allocation of restricted access areas is product-specific and shall be addressed by

product vertical standards.

Allocation of a lamp into a particular risk group is based on the assessment of lamp

emission at a distance of 200 mm and the applicable risk group exposure duration.

However, when a lamp is integrated into a product, depending on product design and

its application, these assessment conditions may become non-representative.
