tem
With respect to the requirements of remote interlock connector, key control, emission warning and attenuator, Class
3B laser products not exceeding five times the AEL of Class 2 in the wavelength range of 400 to 700 nm are to be
treated as Class 3A laser products.
Note: This table is intended to provide a convenient summary of requirements. See text of standard for complete
requirements.

Required as appropriate to the class of accessible radiation
Required under certain conditions as appropriate to the class of laser used
Operation manuals must contain instructions for safe use
Promotion brochures must reproduce classification labels; service manuals must contain
safety information
Cable service connections require tool to disconnect if disconnection breaks protective hous-
