Full title and description

St UL 22 2019-02 — UL 22: Standard for Amusement and Gaming Machines (revision issued February 6, 2019). This document contains safety requirements and test criteria for electrical, electronic and electromechanical commercial amusement and gaming machines and their accessories, intended to ensure safe installation and operation in accordance with applicable electrical codes.

Abstract

UL 22 establishes requirements to address electrical and mechanical hazards, marking, insulation, grounding, overcurrent protection and other safety-related characteristics of commercial amusement and gaming machines intended primarily for indoor use. The 2019-02 revision updates administrative and editorial elements while preserving the technical scope of the standard.

Scope

These requirements cover electrical, electronic, and electromechanical commercial amusement and gaming machines and accessories intended to be used in accordance with the National Electrical Code (NFPA 70). The standard is intended primarily for indoor-use machines; outdoor or protected-location use is investigated only when specifically designated by the manufacturer. The standard excludes coin-operated sound-recording/reproducing machines and carnival rides.

Key topics and requirements

• Electrical safety: insulation, dielectric strength, wiring, and protection against shock.
• Grounding and bonding requirements consistent with NEC references.
• Overcurrent protection and correct selection/installation of fuses and circuit breakers.
• Mechanical safety: guarding of moving parts and stability of cabinetry and assemblies.
• Thermal and fire considerations: temperature limits for components, thermal protection and fire-resistant materials.
• Marking, labeling and instructions for safe installation, operation and maintenance.
• Component acceptance and requirements for motors, transformers, switches and power supplies used in machines.
• Environmental and intended-use limits (indoor use; requirements for protected/outdoor designation).
• Testing procedures and acceptance criteria used by testing laboratories and certification bodies.

Typical use and users

Manufacturers of arcade, commercial amusement and gaming machines; compliance and safety engineers; third‑party testing and certification laboratories; procurement teams verifying equipment safety; and facility operators responsible for safe installation and maintenance. The standard is used during product design, pre‑production testing and final conformity assessment.

Related standards

Designed to be used in conjunction with the National Electrical Code (NFPA 70) and with other UL standards that govern component-level safety (for example standards covering motors, wiring devices and power supplies). It is also referenced by testing bodies when evaluating commercial amusement and gaming equipment.
