It is hard to tell what is just a UL program to bring in more money and what programs actually have some reasonable intent hiding behind the rules.
First, let’s separate out the two sets of label programs. There are Authorized Label Suppliers and there is the program for Marking and Labeling Systems. Authorized Label Suppliers comply with UL’s requirements for printing the registered certification marks. Companies in this program adhere to the requirements in the publication “Printing UL Marks” <http://www.ul.com/global/eng/documents offerings/perspectives/manufacturers/au horizedlabelsuppliers/printingulmarks.pdf> . However, there is no specific UL standard used for the program. This program only means that the supplier has agreed to follow the guidelines on the appearance and use of the marks. These are covered under category code PGAA <h tp://database.ul.com/cgi-bin/XYV/templa e/LISEXT/1FRAME/showpage.html?&name=PGA .GuideInfo&ccnshorttitle=Authorized+Lab l+Suppliers+Program&objid=1076248234&cf id=1073741824&version=versionless&parent_id=1076248233&sequence=1> . This program covers nothing in regards to the material used or durability. Buying labels from an Authorized Label Supplier will not exempt you from any durability testing. UL also has its Marking and Labeling Systems programs. These programs do include the requirements of UL 969 and should exempt you from additional durability testing. PGDQ2 <http://data ase.ul.com/cgi-bin/XYV/template/LISEXT/ FRAME/showpage.html?&name=PGDQ2.GuideIn o&ccnshorttitle=Marking+and+Labeling+Sy tems+-+Component&objid=1073778498&cfgid 1073741824&version=versionless&parent_id=1073778497&sequence=1> covers labels manufactured completely by a label converter. These are sold as finished printed labels, although in some cases, the product manufacturer can add information, such as serial numbers, with approved printer and ink combinations. The UL file for PGDQ2 labels will specify the substrate to which the labels may be applied, temperature range and whether the label is acceptable for outdoor use. Labels printed at the product manufacturer are covered under PGGU2 <http://database.ul.com/cgi-bin/XYV/tem late/LISEXT/1FRAME/showpage.html?name=P GU2.MH11410&ccnshorttitle=Marking+and+L beling+System+Materials+-+Component&obj d=1073782975&cfgid=1073741824&version=v rsionless&parent_id=1073782853&sequence=1> and PGJI2 <http://database.ul.com/cgi-bin/XYV/tem late/LISEXT/1FRAME/showpage.html?&name= GJI2.GuideInfo&ccnshorttitle=Printing+M terials+-+Component&objid=1073783168&cf id=1073741824&version=versionless&parent_id=1073783167&sequence=1> . The first program covers the substrate material and the second covers the combinations of substrate, printer and ink. If you use the right materials and methods under these programs, you shouldn’t have to go through the durability testing. You will almost certainly need this information in your critical components list, but it should give you more flexibility than if you create labels outside of any UL program. In the latter case, you will need to prove durability and you won’t be able to change anything without new testing.

If you use UL 969 approved labelling systems and pass your permanence of marking test, you should be OK. Keep in mind any special environmental conditions (extreme cold, UV exposure, etc) and that the label stock may need to be specifically approved for the material you are expecting it to adhere to. For some reason, UL is now requiring you to pass the permanence of marking test, rather than just accepting the UL 969 labels. -Ken A. - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
