Standardisation work

On an international level, product safety standards for electrically operated products are developed by technical committees of the IEC. For laser equipment, the basic standard is the IEC 60825-1, for lamps and LEDs it is the IEC 62471. 

Limits for the exposure of the eye and the skin (”Maximum permissible exposure“, ”exposure limits“) are established by the experts group ICNIRP on an international level. These ”biological“ limits  are in a complex way dependent on the wavelength of the optical radiation, on the duration of the pulse/exposure, on the retinal spot size and on the pulse pattern.
