Overview
IEC 60061-2:1969/AMD45:2012 is an important amendment to the international standard governing lamp caps, holders, and gauges used to ensure interchangeability and safety. This amendment, released in 2012 by the International Electrotechnical Commission (IEC), focuses on Part 2: Lampholders. It introduces updates and detailed specifications reinforcing standardized dimensions and safety requirements for lampholders worldwide.
The amendment complements the original IEC 60061-2 standard, defining precise construction criteria for various types of lampholders to maintain electrical safety, ensure proper fitting with corresponding lamp caps, and facilitate universal interchangeability across manufacturers and regions.
Key Topics
-
Lampholder Standardization
Amendment 45 updates lampholder specifications to ensure compatibility with various lamp caps such as bayonet, Edison screw, prefocus, and bi-pin types. It contains detailed sheets devoted to a wide variety of lampholder types for domestic, automotive, and industrial applications.
-
Safety and Interchangeability Control
The standard incorporates gauges and design principles to verify critical dimensions of lampholders. This helps prevent hazards caused by poor fitting or incorrect lamp installation, enhancing user and equipment safety.
-
Comprehensive Coverage of Lampholder Types
The amendment covers lampholders including but not limited to:
- Bayonet caps (B22d, BAX9s, BAY9s)
- Edison screw lampholders (E11, E26, E39)
- Prefocus and precision lampholders (EP10, P30s)
- Automotive and special-use lampholders (BA7, BA9, P14.5s)
- Bi-pin and multi-contact lampholders (2G13, GX10q, G6.35)
- Connectors and mounting accessories (PG13, PGJ19)
-
Detailed Design Sheets
Each lampholder type is supported by dedicated documentation sheets specifying dimensional data, assembly distances, and special construction principles drawing from decades of technical revisions, including supplements and previous amendments.
