UL Symbol Undergoes Changes Next Year
Underwriters Laboratories Inc. (UL) will be making two changes to its certification symbol next year, starting on Jan. 1, 2008. This is also the manufacturers' transition deadline for a Dec. 15, 1997, change that was made to the weight of the UL symbol's border in order to make it more prominent on products, packaging, and promotional material.
Starting next year Type L Listing Marks will no longer use the words "Underwriters Laboratories Inc.," which had been the practice in several product categories for many years. Both Type L and Type R Marks will now use only the bolder UL symbol.
Also, the UL Classification Mark will no longer use the words "Underwriters Laboratories Inc. Classified" or "Classified by Underwriters Laboratories Inc." Instead, it will be replaced by a standard UL symbol with the word "Classified" running across the top.
The bolder symbols for both listed and classified products may be downloaded at www.ul.com/marks_labels/mark/art.htm. Also, available at www.ul.com/marks_labels/mark/ul_cul_list_pro.pdf is a description of the proper proportions of the various elements of the UL symbol.
