Overview
IEC 60192:2001 sets out performance specifications and test methods for low-pressure sodium vapour lamps of the integral type, including both U-shaped and linear lamp designs. Published by the International Electrotechnical Commission (IEC), this standard addresses lamps designed for general lighting when operated on alternating current (a.c.) mains at 50 Hz or 60 Hz. IEC 60192 defines the criteria for key electrical, photometric, and mechanical characteristics to ensure product quality, safety, and interoperability. The document facilitates consistency for manufacturers, enhances product compatibility for end-users, and supports quality assurance efforts within the lighting industry.
