Dave, Good question regarding meeting the requirements
when using a standard that is harmonized for use in multiple countries.
When using these standards and including the National
Deviations for more general use then the additional requirements covered by
the NB comments can be invoked, in my opinion.
I have run into this in certifying products to 60950 by a
NRTL; the product bears both the NRTL listing mark as well as the CE
marking..
For labels there are two specific requirements: 1) the
adhesive is proper for the substrate and sticks will and2) the printing is
durable in normal use (and cleaning).
This product uses a UR label which is preprinted by the
supplier for application to the product in manufacturing.
The NRTL US certification includes the labeling material
recognition in the CCL and is accepted as a CCN recognized component for
this application to the specific surface; the testing was performed to
ensure durability the conditions are met.
For the CB Report (including all NDs) the label material is
identified as a UR component in the clause evaluation and shown by name,
type, rating and NA cert standard, and 'subjected to durability testing' for
acceptance on the CCL.
The UR label provides the acceptance for adhering to the
substrate but the printing is evaluated for durability in this case. This
all seems reasonable to me.

Subject: [PSES] Labeling material recognition to UL 969
Hi Folks,
A few NRTLS are requiring labeling material to be recognized to UL 969 and
be included in the critical component list. Anyone running into this?
Anyone know the justification for doing this for product to be Listed to IEC
based standards such as UL 60950-1 and UL 62368-1? Durability is a
requirement with specific test criteria in UL 60950-1 and 62368-1 but not
that is specifically be recognized to UL 969.
Can durability of marking test called out in ICT standards such as
IEC/CSA/UL 60950-1 and IEC/CSA/UL 62368-1 be waived for UL 969 recognized
material?
Thanks
-Dave
