Standards compliance
The product complies with both IEC standards and the Food and Drug Administration's
Center for Devices and Radiological Health (FDA/ CDRH) regulations.
FDA/CDRH regulations
Laser products are classified in accordance with the FDA/CDRH - 21 CFR 1010 and 1040.
The classification scheme is based on the ability of the laser emission to cause injury to
eye or skin during normal operating conditions.
In the United States, lasers and laser systems in the infrared wavelength range (greater
than 700 nm) are assigned to one of the following classes:
Class I,
•
Class IIIb, or
•
Class IV.
•
Laser classification is dependent upon operating wavelength, output power and fiber
modefield diameter (core diameter).
IEC requirements
There are five major differences between the FDA/CDRH regulations and the IEC
requirements:
According to the IEC classification, lasers and laser systems in the infrared wavelength
range (greater than 700 nm) are assigned to one of the following classes:
Class 1, 1M
•
Class 3R
•
Class 3B
•
Class 4.
•
There are some major differences between the FDA/CDRH regulations and IEC:
The Accessible Emission Limits (AEL) are different
•
Class 3R applies to all wavelengths
•
Class 3B requires strict engineering controls
•
Classification is under single fault conditions (IEC).
