In 2001 the standard governing the safety of laser products in europe en and internationally iec was substantially revised and the classification system was overhauled.
International laser classification.
Not true if the laser is a continuous wave laser at the mid to upper end of the class 3b classification.
Below is a brief description of each of the current laser classes.
Class 1 laser products safe under reasonably foreseeable conditions of operation including the use of optical instruments for intrabeam viewing.
Due to their high focused power output international laser safety standards have been established.
The class of the laser can be used to help decide what safety control measures are required when using the laser.
Includes international laser class activities with information addresses and links to many other laser sailing sites.
Class 3b lasers do not have a thermal effect.
Laser printers and compact disc players.
The international electrotechnical commission iec is a global organization that prepares and publishes international standards for all electrical electronic and related technologies.
If the laser has a suitable power density and is held in place for a period of time tissue burns can occur.
In the united states laser product regulations are summarised by the fda cdrh standard 21 cfr 1040 10.
This shows the distances at which various consumer lasers are eye skin and fire hazards and are visual interference hazards.
Iec 60825 1 is an international standard for laser products and has become a common safety standard in iec member countries.
The international classification described in consensus standards such as iec 825 later iec 60825 was based on the same concepts but presented with designations slightly different from the us classification.
The hazard and hence the classification depends on the wavelength power energy and pulse characteristics.

This classification system is only slightly altered from the original system developed in the early 1970s.
Get a sense of the laser safety requirement for the safe use of lasers in industrial environment by reading the following.
Flashblindness glare and distraction.
Laser radiation can cause severe damages to eyes and skin.
Laser classification lasers are grouped into seven classes depending on the potential for the beam to cause harm.
Classification is based on calculations and determined by the.
The iec document 60825 1 is the primary standard that outlines the safety of laser products.
