1. SCOPE
This International Standard gives guidance for evaluating the photobiological safety of lamps and lamp systems including luminaires. Specifically it specifies the exposure limits, reference measurement technique and classification scheme for the evaluation and control of photobiological hazards from all electrically powered incoherent broadband sources of optical radiation, including LEDs but excluding lasers, in the wavelength range from 200 nm through 3000 nm.

3. DEFINITIONS, SYMBOLS AND ABBREVIATIONS
For the purposes of this standard, the following definitions, symbols and abbreviations apply.
3.1 actinic dose (see ILV 845-06-23)
Quantity obtained by weighting spectrally the dose according to the actinic action spectrum value at the corresponding wavelength.
Unit: J⋅m -2
Note: This definition implies that an action spectrum is adopted for the actinic effect considered, and that its maximum value is generally normalized to 1. When giving a quantitative amount, it is essential to specify which quantity dose or actinic dose is meant, as the unit is the same.
3.2 angular subtense (α)
Visual angle subtended by the apparent source at the eye of an observer or at the point of measurement. In this standard subtended angles are denoted by the full included angle, not the half angle.
Unit: radian
Note: The angular subtense α will generally be modified by incorporation of lenses and mirrors as projector optics, i.e. the angular subtense of the apparent source will differ from the angular subtense of the physical source.
3.3 aperture, aperture stop
Opening that defines the area over which average optical emission is measured. For spectral irradiance measurements this opening is usually the entrance of a small sphere placed in front of the radiometer/spectroradiometer entrance slit.
