Industry Standards for Display Cabinets

UL 970 is the primary industry standard for retail and commercial display cabinets, covering safety, construction, and performance requirements for both electrified and non-electrified units.

U

L 970: Retail Fixtures and Merchandise DisplaysUL 970 is the consolidated standard that replaced UL 65 (Wired Cabinets) and UL 962 (Household and Commercial Furnishings), providing a unified framework for retail display cabinets, showcases, and temporary displays. Published in 2020, it addresses modern innovations such as embedded electronics, LED lighting, and motorized components. Key aspects include: Scope: Covers non-refrigerated or heated commercial displays, shelving units, merchandise kiosks, point-of-sale displays, motorized displays, wall systems, check-out stands, and temporary displays.

Electrical Requirements: Applies to products rated 600 V AC or less, including battery-powered units, and is intended for dry, damp, or wet locations. Safety and Construction: Ensures structural integrity, fire safety, and safe operation of electrified components, including compliance with the National Electrical Code (ANSI/NFPA 70) for electrical installations. Certification Benefits: Provides a single standard for manufacturers to streamline certification, access flexible construction programs, and utilize limited production programs for specialized displays.

ANSI/UL 970 ComplianceANSI/UL 970, effective February 20, 2022, formalizes the requirements for commercial displays and temporary fixtures, ensuring manufacturers meet updated safety and performance criteria. Compliance includes testing for electrical safety, mechanical stability, and proper labeling.

Display Measurement Standards

For electronic display cabinets, the International Committee for Display Metrology (ICDM) provides the Information Display Measurements Standard (IDMS), which defines measurement procedures for display characteristics such as brightness, contrast, color accuracy, and uniformity.

While ICD

M does not set compliance values, it ensures consistent and reproducible measurement methods across display technologies, supporting quality control and performance verification.

Additional Considerations

Lighting and Energy Efficiency: Standards such as ANSI/IES RP-2-20 emphasize lighting quality and energy efficiency in retail displays, ensuring optimal product visibility while minimizing energy consumption. Temporary and Limited Production Displays: UL 970 includes provisions for temporary displays and limited production units, allowing flexibility in design while maintaining safety compliance. In summary, UL 970 and ANSI/UL 970 are the primary standards governing the safety, construction, and certification of display cabinets in retail and commercial environments, while ICDM/IDMS provides measurement standards for electronic display performance.

Manufacturers and retailers should adhere to these standards to ensure safety, regulatory compliance, and consistent display quality.
