General IEC label requirements

All labels provided under clause 5 of 60825-1:
  • Must be permanently fixed, legible and visible according to their purpose
  • Must be read without the necessity for human exposure to laser energy in excess of the limits associated with Class 1
  • Text, borders and symbols shall be black on a yellow background — except for Class 1 certification and identification labels
  • The terms “Invisible” or “Visible and Invisible” shall be added before the term “Laser Radiation” when appropriate
  • The term “Laser Radiation” may be substituted by the words “Laser Light” when only visible laser light is emitted
  • For laser products complying with IEC 60825-1, 2001-08 Edition 1.2, LED radiation must be included. The text “LED” shall be substituted or added to the word “Laser” as appropriate.

Note: If the size or design of the product makes labeling impractical, the label should be included with the user information or on the package.
