Attached is Laser Notice 50 issued by the CDRH in 2001. It allows you to use comparable sections from IEC 60825-1/A2 which includes labeling.

Regarding labelling, there have been efforts (not sure of the status at this time - is there anyone out there who knows?) to harmonize the EN 60825 and 21CFR1040 to make it easier on manufacturers. As the final laser classifications are parallel (it's the methodology that has differences) the FDA, in the interest of manufacturer satisfaction(?) has been allowing the use of the Classification/Warning labels as described in EN 60825. But you still have to add the FDA-CDRH label "This product complies with FDA Radiation Performance Standard 21 CFR Subpart J" Hope this helps.

And I will add, Doug is speaking of the FDA-CDRH requirement for the US. But, to ascertain what the European mode is, this requires a single-fault condition for classification as described by John Juhasz. That, I understand. John, is there a free downloadable copy of ANSI Z136.1 and .2 specs? I have used the calculations to determine the classification of a laser based on the no fault and a single fault mode. These lasers are operating in a pulsed mode at a 50% duty cycle. I have attached a sample calculation of a 1310nmn and a 1550nm laser that I used to determine that the lasers either do or do not fall within the Class 1 laser classification. Another question... Can the same label be used for FDA as for IEC? Has anyone had any feedback or problems with laser labels that deviated from recommended markings by the 21 CFR or IEC 825-1? ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
