Are Marking & Labeling Systems evaluated for electrical ratings, flammability ratings, or for structural strength?
In the Marking & Labeling Systems program, UL evaluates labels only with respect to permanence of marking requirements and not flammability, electrical, or structural performance. If a label is used in an application where an electrical rating or flammability rating is required, or is used to bond structural parts together, these issues would be addressed during the end-product evaluation with the complete equipment. Adhesives intended for use in bonding structural parts or components are covered under the Polymeric Adhesive Systems, Electrical Equipment-Component program (category code QOQW2). Electrical and flammability ratings for polymeric materials are covered under the Plastics-Component program (category code QMFZ2).
