UL 969 Marking & Labeling Systems Program:
The Marking and Labeling Systems program covers labels (nameplates or markers) and label materials that have been submitted to UL for evaluation in accordance with prescribed permanence of marking performance requirements so they can be used to display information on products. Most products are required to be permanently marked with specific safety-related information such as hazards, warnings, cautionary markings, installation instructions, electrical ratings, etc. Labels and label materials that comply with the Marking and Labeling System requirements fall under UL’s Component Recognition Program which provides a convenient way for manufacturers to acquire labels that meet performance of marking requirements applicable to their UL certified product. Marking and Labeling Systems are covered under the following five categories based on the type of product and end-use application.
- PGDQ2: Marking & Labeling Systems
- PGJI2: Marking & Labeling Systems – Printing Materials
- PGIM2: Marking & Labeling Systems -In-Mold
- PGGU2: Marking & Labeling Systems – Materials
- PGIS2: Marking & Labeling Systems – Limited Use
Labels and label materials Recognized under the first four category codes – PGDQ2, PGJI2, PGIM2 and PGGU2 – are tested in accordance with the test methods in ANSI/UL 969, “Marking & Labeling Systems”. They are suitable for use on a wide variety of UL Certified products.
Labels Recognized under the category code PGIS2 are evaluated in accordance with unique label requirements in a specific UL end-product Standard and are thus “limited in use” to the products covered under that Standard.
The evaluation for Marking and Labeling Systems includes a construction examination and testing for permanency. Environmental conditioning of labels typically includes testing for exposure to high humidity or occasional exposure to water, elevated temperatures, sunlight resistance, or exposure to chemical agents. After the environmental conditioning, the labels are visually examined for curling, wrinkling, shrinkage or loss of adhesion around the perimeter. Testing also typically includes evaluation of legibility, resistance to defacement, and adhesion.
The Directives mandates that anything within the end product which can be identified as a homogeneous material (ex. paper, wood, glue, etc) must be tested. As such, if the labels are part of the packaging that will be discarded before use, they don’t fall within the scope. However, if the labels are permanently affixed to the product, they may be subject to compliance certification.
MSI offers a wide variety of RoHS-2/REACH compliant materials and labels.
