Understanding UL969 Labels for Use with Electric Signs

In the world of electric signs, there seems to be an ever-increasing conversation around compliance and UL969 labeling. Here at Melrose, we’ve definitely seen an increase in activity around UL-compliant labels for many electric sign manufacturers. One of the key standards governing labels used on electric signs is UL969, the “Standard for Marking and Labeling Systems.” This article explores the essential elements of UL969 labels, their purpose, and best practices for their use in electric signs.

What is UL969?

UL969 is a certification standard developed by Underwriters Laboratories (UL) to evaluate the durability and performance of marking and labeling systems. It ensures that labels (including materials & inks) can withstand environmental conditions, maintain legibility, and remain securely affixed to a variety of surfaces over time.

Key Requirements for UL969 Labels

To comply with UL969, labels must meet specific criteria in areas such as:

  1. Adhesion: Labels must adhere firmly to the substrate material (e.g., metal, plastic) and resist peeling, curling, or detaching over time.
  2. Legibility: Text, symbols, and colors on the label must remain legible under environmental conditions such as UV exposure, moisture, and temperature fluctuations.
  3. Durability: Labels are tested for resistance to chemicals, abrasion, and weathering to ensure they can endure harsh conditions without degradation.
  4. Compatibility: Labels must be compatible with the surface materials of the electric sign, ensuring consistent and reliable performance.

Applications of UL969 Labels in Electric Signs

Labels on electric signs serve various purposes, including:

  • Identification: Displaying the manufacturer’s name, model number, and serial number.
  • Warnings and Instructions: Providing safety information, such as electrical warnings or maintenance instructions.
  • Certification Marks: Indicating compliance with UL or other safety standards.

These labels are critical for ensuring the safe installation, operation, and maintenance of electric signs.

Best Practices for Using UL969 Labels on Electric Signs

  1. Choose a Certified Label Supplier: Always work with a UL969 authorized printer and ensure they provide any necessary documentation required for you to successfully pass any audit or inspection.
  2. Match Materials: Work with a UL label printer that has an approved construction that is compatible with your sign’s specific requirements – temperature, environment, and adhesion.
  3. Proper Placement: Position labels in areas where they are easily visible but protected from excessive wear or damage.
  4. Follow Installation Guidelines: Adhere to manufacturer recommendations for surface preparation and label application. Very important that your UL969 print provider help you with the proper installation instructions.

The Importance of Compliance

Using UL969-certified labels on electric signs is not just about meeting regulatory requirements. It ensures safety, reliability, and clear communication of all the essential information. Non-compliance can result in safety risks, regulatory penalties, and reputational damage.
