My experience with labeling is as long as all the required information is available you can use a single label. In fact on my product I have two labels the first indicates the opening with "AVOID EXPOSURE - Laser Light Emitted From This Aperture". The second has the IEC label information, FDA information, model number, date code, address, and other useless information.

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?
