UL 496:2013 STANDARD FOR SAFETY – Lampholders

UL 496:2013 is a safety standard governing lampholders for incandescent, fluorescent, and other discharge lamps, along with related parts like lamp shade holders and GU24/GU24-1 bases for LED self-ballasted lamps. It focuses on mitigating electrical and mechanical hazards, covering aspects such as insulation integrity (to prevent leakage/short circuits), ground continuity (against electric shock), mechanical durability (e.g., torque for screw bases, insertion force for pin bases), and compatibility with lamp caps. It also mandates structural safeguards, like blocking accidental contact with live components and ensuring stable mounting in luminaires.

For compliance verification, UL 496:2013 does not independently detail material flammability tests (e.g., horizontal/vertical burning). Instead, it references standards like UL 94 to specify flammability ratings (e.g., V-0) for components such as plastic housings. The standard also includes environmental and long-term reliability requirements (e.g., resistance to humidity/temperature changes). Overall, compliance relies on rigorous testing of electrical, mechanical, and structural properties to reduce risks of fire, shock, or failure during use.
