Brian,

I can't help you with the TUV mark, but with reference
to the UL mark,  UL does offer some simple guidance in the
Follow-Up Services procedure (if you have a UL
listed product, then you should have an FUS procedure).
The first paragraph says:
"The Listing Mark consists of four elements placed in close
proximity and shall appear on Listed products only
Minimum size is not specified, as long as the Listing
Mark is legible. . . . "

Then about half way down the Listing Mark Data Page,
you should find the following paragraph:
"The minimum height of the registered trademark symbol
('R' in a circle, located under the 'U') shall be
3/64 of an inch. When the overall diameter of the UL
mark is less than 3/8 of an inch, the trademark symbol
may be omitted, if it is not legible to the naked eye."

I hope this helps.

Good People

I have not been able to find any requirements on the TUV or UL websites for
minimum size requirements of their respective logos (when used as a safety
mark on the recognized/certified product).

Could someone provide a pointer to (agency-published) guidance for logo
dims?

Thanks Much,
