Rich and others,

Here is what the Listing Mark Data Page says in one of our FUS books for a
piece of Listed ITE equipment that was Listed to UL 1950. Note number 3
below stating that you can use the File Number or the Control Number. By the
way we create our own Listing Mark labels using the downloadable Listing
Marks from the UL website and a label maker and software combination
manufactured by Brady.

PROCUREMENT

All Listing Marks shall be obtained from a supplier authorized by
Underwriters Laboratories Inc. unless the Listing Mark is molded, cast,
die-stamped, rubber stamped, silk screened or reproduced by the
manufacturer.

COMPOSITION AND ELEMENTS

1. UL in circle symbol
2. The word "LISTED"
3. The assigned control number(s) or the Applicant/Listee's File Number
4. Product identity. Consists of the following:

"UL 1950", "NWGQ", "INFORMATION TECHNOLOGY EQUIPMENT", INFO. TECH. EQUIP.",
or "I.T.E." In addition, the name or the specific type of product as shown
on the individual Listing (i.e. 'ADDING MACHINE", "CALCULATOR", "PRINTER",
"PERSONAL COMPUTER", etc.) may also be noted.

If the first three elements are directly applied to the product by
die-stamping, ink-stamping, silk screening, molding, etching, or similar
processes, or if they are part of a nameplate which includes either the
electrical rating or the catalog or model designation, the product identity
may appear elsewhere on the product.

Minimum size is not specified as long as the Listing Mark is legible. The
first three elements shall be in close proximity.

SEPARABLE LISTING MARK

If separable Listing Marks are employed, all four elements are required to
be part of the sticker, label, decal, etc. (A separable Listing Mark is one
which bears only the Listing Mark information and is separately applied.)

Rich,

For ITE, the file number may be used in lieu of control number. I will be
glad to provide a memo from UL Labels Department regarding this issue.

Hi Ron:

The file number cannot replace the control number.
The control number is always required.

The file number can replace the manufacturer's name,
or can be used in addition to the manufacturer's
name.

The generic UL mark (the UL in a circle -- without the
other three items) may be used in advertising or on 
the product carton.  I believe UL has some guidelines 
for this use.


Best regards,
Rich
