The exposure limit for effective radiant exposure is 30 J. m -2 within any 8-hour period To protect against injury of the eye or skin from ultraviolet radiation exposure produced by a broadband source, the effective integrated spectral irradiance, E S, of the light source shall not exceed the levels defined by: The permissible time for exposure to ultraviolet radiation incident upon the unprotected eye or skin shall be computed by: Near-UV hazard exposure limit for eye Considered. For the spectral region 315 nm to 400 nm (UV-A) the total radiant exposure to the eye shall not exceed J. m -2 for exposure times less than 1000 s. For exposure times greater than 1000 s (approximately 16 minutes) the UV-A irradiance for the unprotected eye, E UVA, shall not exceed 10 W. m -2. The permissible time for exposure to ultraviolet radiation incident upon the unprotected eye for time less than 1000 s, shall be computed by: Retinal blue light hazard exposure limit Considered.

10 age 10 of 29 To protect against retinal photochemical injury from chronic blue-light exposure, the integrated spectral radiance of the light source weighted against the blue-light hazard function, B(λ), i.e., the blue-light weighted radiance, L B, shall not exceed the levels defined by: for t 10 4 s for t > 10 4 s Retinal blue light hazard exposure limit - small source Thus the spectral irradiance at the eye E λ, weighted against the blue-light hazard function B(λ) shall not exceed the levels defined by: (see appended table 4.2) for t 100 s for t > 100 s Retinal thermal hazard exposure limit To protect against retinal thermal injury, the integrated spectral radiance of the light source, L λ, weighted by the burn hazard weighting function R( λ ) (from Figure 4.2 and Table 4.2), i.e., the burn hazard weighted radiance, shall not exceed the levels defined by: (10 μs t 10 s) Retinal thermal hazard exposure limit weak visual stimulus For an infrared heat lamp or any near-infrared source where a weak visual stimulus is inadequate to activate the aversion response, the near infrared (780 nm to 1400 nm) radiance, L IR, as viewed by the eye for exposure times greater than 10 s shall be limited to: t > 10 s Infrared radiation hazard exposure limits for the eye Considered.

11 age 11 of 29 The avoid thermal injury of the cornea and possible delayed effects upon the lens of the eye (cataractogenesis), ocular exposure to infrared radiation, E IR, over the wavelength range 780 nm to 3000 nm, for times less than 1000 s, shall not exceed: t 1000 s For times greater than 1000 s the limit becomes: t > 1000 s Thermal hazard exposure limit for the skin Considered. Visible and infrared radiant exposure (380 nm to 3000 nm) of the skin shall be limited to: 5 MEASUREMENT OF LAMS AND LAM SYSTEMS 5.1 Measurement conditions Measurement conditions shall be reported as part of the evaluation against the exposure limits and the assignment of risk classification. (see above) Lamp ageing (seasoning) LED Source. Seasoning of lamps shall be done as stated in the appropriate IEC lamp standard Test environment For specific test conditions, see the appropriate IEC lamp standard or in absence of such standards, the appropriate national standards or manufacturer s recommendations. Standard laboratory (dark room) condition Extraneous radiation Considered. Careful checks should be made to ensure that extraneous sources of radiation and reflections do not add significantly to the measurement results Lamp operation Operation of the test lamp shall be provided in accordance with: the appropriate IEC lamp standard, or the manufacturer s recommendation Lamp system operation

12 age 12 of 29 The power source for operation of the test lamp shall be provided in accordance with: the appropriate IEC standard, or the manufacturer s recommendation 5.2 Measurement procedure Irradiance measurements Minimum aperture diameter 7mm. Maximum aperture diameter 50 mm. The measurement shall be made in that position of the beam giving the maximum reading. The measurement instrument is adequate calibrated. Considered. Measurement system calibrated with standard lamps Radiance measurements Standard method The measurements made with an optical system. The instrument shall be calibrated to read in absolute radiant power per unit receiving area and per unit solid angle to acceptance averaged over the field of view of the instrument Alternative method Alternatively to an imaging radiance set-up, an irradiance measurement set-up with a circular field stop placed at the source can be used to perform radiance measurements. For 100mrad L B measurement Measurement of source size The determination of α, the angle subtended by a source, requires the determination of the 50% emission points of the source. 1) CLU C4-403Mzab mm x mm α = mrad 2) CLU C4-403Mzab mm x mm α = mrad 3) CLU C4-403Mzab 21.45mm x 21.40mm α = mrad ulse width measurement for pulsed sources Continuous Wave lamps. The determination of Δt, the nominal pulse duration of a source, requires the determination of the time during which the emission is > 50% of its peak value. 5.3 Analysis methods Weighting curve interpolations

13 age 13 of 29 To standardize interpolated values, use linear interpolation on the log of given values to obtain intermediate points at the wavelength intervals desired. (see appended table 4.1) Calculations The calculation of source hazard values shall be performed by weighting the spectral scan by the appropriate function and calculating the total weighted energy Measurement uncertainty The quality of all measurement results must be quantified by an analysis of the uncertainty. 6 LAM CLASSIFICATION For the purposes of this standard it was decided that the values shall be reported as follows: for lamps intended for general lighting service, the hazard values shall be reported as either irradiance or radiance values at a distance which produces an illuminance of 500 lux, but not at a distance less than 200 mm for all other light sources, including pulsed lamp sources, the hazard values shall be reported at a distance of 200 mm (see appended table 6.1) Non-GLS 6.1 Continuous wave lamps Exempt Group In the exempt group are lamps, which do not pose any photobiological hazard. The requirement is met by any lamp that does not pose: an actinic ultraviolet hazard (E S ) within 8-hours exposure (30000 s), nor a near-uv hazard (E UVA ) within 1000 s, (about 16 min), nor a retinal blue-light hazard (L B ) within s (about 2,8 h), nor a retinal thermal hazard (L R ) within 10 s, nor an infrared radiation hazard for the eye (E IR ) within 1000 s Risk Group 1 (Low-Risk) In this group are lamps, which exceeds the limits for the exempt group but that does not pose: an actinic ultraviolet hazard (E S ) within s, nor

14 age 14 of 29 a near ultraviolet hazard (E UVA ) within 300 s, nor a retinal blue-light hazard (L B ) within 100 s, nor a retinal thermal hazard (L R ) within 10 s, nor an infrared radiation hazard for the eye (E IR ) within 100 s Lamps that emit infrared radiation without a strong visual stimulus and do not pose a near-infrared retinal hazard (L IR ), within 100 s are in Risk Group Risk Group 2 (Moderate-Risk) This requirement is met by any lamp that exceeds the limits for Risk Group 1, but that does not pose: an actinic ultraviolet hazard (E S ) within 1000 s exposure, nor a near ultraviolet hazard (E UVA ) within 100 s, nor a retinal blue-light hazard (L B ) within 0,25 s (aversion response), nor a retinal thermal hazard (L R ) within 0,25 s (aversion response), nor an infrared radiation hazard for the eye (E IR ) within 10 s Lamps that emit infrared radiation without a strong visual stimulus and do not pose a near-infrared retinal hazard (L IR ), within 10 s are in Risk Group Risk Group 3 (High-Risk) Lamps which exceed the limits for Risk Group 2 are in Group ulsed lamps Continuous Wave lamps. ulse lamp criteria shall apply to a single pulse and to any group of pulses within 0,25 s. A pulsed lamp shall be evaluated at the highest nominal energy loading as specified by the manufacturer. The risk group determination of the lamp being tested shall be made as follows: a lamp that exceeds the exposure limit shall be classified as belonging to Risk Group 3 (High- Risk) for single pulsed lamps, a lamp whose weighted radiant exposure or weighted radiance does is below the EL shall be classified as belonging to the Exempt Group

15 age 15 of 29 for repetitively pulsed lamps, a lamp whose weighted radiant exposure or weighted radiance dose is below the EL, shall be evaluated using the continuous wave risk criteria discussed in clause 6.1, using time averaged values of the pulsed emission
