SIST EN 60061-1:1999/A64:2026

Overview

SIST EN 60061-1:1999/A64:2026 is a key amendment to the European and international standard for lamp caps, as part of the comprehensive IEC 60061 series. This standard, issued by the Slovenian Institute for Standardization (SIST) and aligned with IEC 60061-1:1969/AMD64:2025, specifies requirements for lamp caps-the components at the end of lamps that enable secure and safe electrical connection with lamp holders. The document sets out the standardized dimensions, shapes, and critical interfaces to ensure both and across a wide range of lighting product types. Consistency with these requirements is crucial for manufacturers, test laboratories, and compliance bodies engaged in lamp and luminaire design, production, and certification.
