We are developing an ITE product for the EU market that includes a Class 2
LED that produces Class 1 emissions outside the product. After review of
EN60950 and EN60825-1, I believe that the following requirements apply. The
clause references are in parentheses.
When assembled for normal operation
1. No part of the human body may be exposed to Class 2 emissions (3.16)
2. An inserted 12 mm diameter probe up to 80 mm long cannot intercept
Class 2 emissions (3.3.2)
3. No part of the human body may be exposed to reflections of Class 2
emissions from a flat surface introduced through any opening in the
protective housing (3.32)
4. "Class 1 Laser Product" label required on product or in information
for the user (5.2)
When being serviced
1. A tool shall be required to gain human access to Class 2
emissions (4.2.2)
2. "Caution - Laser Radiation (or laser light) When Open, Do
Not Stare Into Beam" label on cover. "Light" may be substituted for
"Radiation" and "LED" for "Laser" (5.11 and 5.12). TUV GS marking requires
the warning to be in German (EN60950, Annex ZC, 1.7.14).
User Information
The following information is to be supplied in user information, if any
(6.1). The information must be in one of the accepted languages of the
country (EN60950, 1.7.14).
1. Instructions for proper assembly, maintenance, and safe use
including clear warnings concerning precautions to avoid possible exposure
to Class 2 emissions.
2. A description of the Class 2 emissions (e.g., wavelength)
3. Reproductions of all required labels and hazard warnings
with the location on the product noted.
Purchasing and Servicing Information
1. In all catalogs, specification sheets and descriptive
brochures, the safety classification (Class 1) shall be stated (6.2a)
2. Adequate instructions for service procedures including
warnings shall be provided to servicing dealers, distributors and to others
upon request (6.2b).
3. Service instructions intended only for service personnel may
be in English (EN60950 1.7.14), except that TUV GS marking requires the
instructions to be in German (EN60950, Annex ZC, 1.7.14).
Did I get anything wrong or is there anything missing?
