The international electrotechnical commission iec is a global organization that prepares and publishes international standards for all electrical electronic and related technologies.
International laser classification.
Laser classification lasers are grouped into seven classes depending on the potential for the beam to cause harm.
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.
According to the international electrotechnical commission iec standard laser products are classified as follows.
Class 1 laser products safe under reasonably foreseeable conditions of operation including the use of optical instruments for intrabeam viewing.
Flashblindness glare and distraction.
If the laser has a suitable power density and is held in place for a period of time tissue burns can occur.
This classification system is only slightly altered from the original system developed in the early 1970s.
See also the laser hazard distance chart.
The iec document 60825 1 is the primary standard that outlines the safety of laser products.
This resulted in the introduction of three new laser classes 1m 2m and 3r and the abolition of class 3a.
Includes international laser class activities with information addresses and links to many other laser sailing sites.
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.
Class 3b lasers do not have a thermal effect.
The class of the laser can be used to help decide what safety control measures are required when using the laser.
Not true if the laser is a continuous wave laser at the mid to upper end of the class 3b classification.
For information about laser classifications in general see this page from rockwell laser industries.
Laser printers and compact disc players.
Iec 60825 1 is an international standard for laser products and has become a common safety standard in iec member countries.
In the united states laser product regulations are summarised by the fda cdrh standard 21 cfr 1040 10.
Heat is a by product of the tissue absorbing the laser emission.
Below is a brief description of each of the current laser classes.
Laser radiation can cause severe damages to eyes and skin.
Get a sense of the laser safety requirement for the safe use of lasers in industrial environment by reading the following.
The hazard and hence the classification depends on the wavelength power energy and pulse characteristics.
Classification is based on calculations and determined by the.
