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: t max 10000/E UVA s age 3 of 16 E UVA = W m Retinal blue light hazard exposure limit 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(_), i.e., the blue-light weighted radiance, LB, shall not exceed the levels defined by:

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 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 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 ulse width measurement for pulsed sources The determination of t, 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 To standardize interpolated values, use linear interpolation on the log of given values to obtain intermediate points at the wavelength intervals desired 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 CLASSIFICATIO age 6 of 16

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 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 age 8 of 16
