Requirements from Regulations and Standards
Manufacturer's Requirements
EN60825 (IEC60825) "Radiation Safety of Laser Products, Equipment Classification, Require-
ments and User's Guide"
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.

Classification
Class 1 Class 2 Class 3A Class 3B Class 4
Description of
hazard class
Safe inherently
by engineering
design
Low power;
eye protection
normally
afforded by
aversion
responses
Same as Class
2. Direct intra-
beam viewing
with optical
aids may be
hazardous
Direct intra-
beam viewing
may be hazard-
ous
High power;
diffused reflec-
tion may be
hazardous
Protective hous-
ing
Required for each laser product; limits access necessary for performance of
functions of the products
Safety interlock in
protective housing
Designed to prevent removal of the panel until accessible emission values are
below the AEL for the class assigned
Remote control
Not required
Permits easy addition of exter-
nal interlock in laser installation
Key control
Not required
Laser inoperative when key is
removed
Emission warning
device
Not required
Give audible or visible warning
when laser is switched on or if
capacitor bank of pulsed laser
is being charged
Attenuator
Not required
Give means beside ON/OFF
switch to temporarily block beam
Location controls
Not required
Controls located so adjustment does not require
exposure to AEL above class 1 or 2
Viewing optics Emission from all viewing systems must be below Class 1 AEL's as applicable
Scanning Scan failure shall not cause product to exceed its classification
Class label Required word-
ing Warning and explanatory labels and specified wording (Refer to
page 12)
Aperture label Not required Specified wording required
Service entry
label
Required as appropriate to the class of accessible radiation
Override interlock
label
Required under certain conditions as appropriate to the class of laser used
User information Operation manuals must contain instructions for safe use
Purchasing and
service informa-
tion
Promotion brochures must reproduce classification labels; service manuals must
contain safety information
Medical products
Special calibration instructions required
Special calibration instructions,
means for measurement and
target-indicator required
Fibre optic Cable service connections require tool to disconnect if disconnection breaks pro-
tective housing and permits access above Class 1
