When UL approval is required

Don't know whether an E number is the same thing, but this is from a FAQ on the UL site:

Does an E-number on a product mean that it is UL Listed?

No. The UL E-number is a valid identifier for the organization responsible for a product but not an indication that the product is Listed, Classified, verified or Recognized. Only the appropriate UL Mark -- on the wire or cable or on its packaging -- is a valid indication of UL certification. UL assigns a unique E-number (E and a 3- to 6-digit number for wire and cable products) to each applicant in every product category. To find the responsible organization for a product when the E-number has been used for identification, go to UL's Online Certifications Directory, select "Search By UL File Number" and enter the E-number.

(My emphasis in bold face)

I mean if our customer requires us to mark say UL 2586 on the cable. Does that mean it has to be UL approved or just have to comply to the requirements.

I think it's OK to put UL like that, as it indicates a recognized style number - as long as you don't use the actual UL marks: or (or any of the other UL marks listed here).

Warning - I'm just some bloke you talked to on the internet - I could be making it all up as I go along. I'd advise you to check with UL directly before doing anything rash. E-mailing is a better move than 'phoning, as you'll have a written record of the correspondence.

While I encourage you to check the UL site as advised by JohnDG, a form of indication that the cable conforms to say, UL2586 will not be a bad idea.

For example a mark like: Conforms to UL2586 or UL286 Equivalent

And be sure the said cable conforms to the said UL standard in fact.

If you, "mark certain UL style number on the product" you are implying that it is listed. Listing implies testing.

Depends on what role you play in determining that the product is legitimate. If you are building the item to a customer's spec and he says it's tested and signs off on that, you're off the hook.

You're just a supplier.

If I recall correctly . . . years ago I don't think UL would even allow us to put in print that UL approval was applied for and pending. They were very strict. It is UL approved/listed or you do not do anything to suggest that it is UL approved/listed.

You might consider reviewing the following dictionary definition. Keep in mind that no matter how you construct your argument it is still true that people use the UL markings as a "checkmark item". If it has the UL marking then people are going to assume it is UL approved/listed.

coun·ter·feit

–noun. an imitation intended to be passed off fraudulently or deceptively as genuine; forgery.

Regardless of the OP's intention, you are correct.

Looking back at my response, it appears to subtly, encourage counterfeiting.It is not intended to be so.

Thus the OP is encouraged to submit to UL's approval prior to inserting the mark.

Thanks for so many advise that helped get some Idea. Now the point is, our customer is asking TO PRINT `AWM style No. 10513 AND 21254' on the cable. I could not any reference to these styles on google search. can some one guide the details about these styles.

Thanks in advance.

You are talking of something like AWG (American Wire Guage) and SWG (Standard Wire Guage) see these sites from wikipedia. I'm sure you'll be well guided: http://en.wikipedia.org/wiki/American_wire_gauge , http://en.wikipedia.org/wiki/IEC_60228, http://en.wikipedia.org/wiki/Standard_wire_gauge, http://upload.wikimedia.org/wikipedia/en/2/28/Gauge_Chart.pdf

Beg to differ. AMW is a wire or cable style - not just a wire gauge. Please see this list of styles for examples. I haven't been able to locate the particular style numbers (10513 and 21254) that the OP is looking for.

Thanks for the correction, I'll go with you.

Yes these are Appliance wiring material (AWM) and the requirement is 2 core, 14 AWG conductors with FRPE Insulation and FRPE Jacket. These are used for DC circuits in telecom equipment.

Now can any one interpret what is meant by the numbers 10513 and 21254
