Overview
The IEC 60061-2:1969/AMD42:2011 standard, titled "Amendment 42 - Lamp caps and holders together with gauges for the control of interchangeability and safety - Part 2: Lampholders," issued by the International Electrotechnical Commission (IEC), is a critical update in the global standardization of lampholders. This amendment introduces precise specifications for lamp lampholders and their interchangeable compatibility, ensuring enhanced safety and uniformity across lighting components worldwide.
IEC 60061-2 serves as an extension and revision to the foundational IEC 60061-2 (1969) series, detailing construction and dimensional requirements for lampholders used in various lamp types. By subscribing to the IEC 60061 database, stakeholders can access the complete and continuously updated content of this important series.
Key Topics
Lampholder Design and Interchangeability
- Detailed specifications for a broad range of lampholders including bayonet, Edison screw, prefocus, and automotive types.
- Standardization of thread positions, contact arrangements, and mounting distances to ensure lampholders are interchangeable and compatible with respective lamp caps.
- Gauges and measurement tools specified for controlling dimensional conformity and interchangeability.
Safety Considerations
- Definition of safety parameters for lampholder construction aimed at preventing electrical hazards.
- Norms for insulation, contact spacing, and mechanical robustness to promote user safety.
- Requirements ensuring lampholders prevent improper lamp fitting, thereby reducing risks of malfunction or fire.
Comprehensive Coverage of Lampholder Types
The amendment provides specific sheets for lampholders addressing:
- Various bayonet lampholders (e.g., B22d, BA7, BA15).
- Edison screw lampholders (e.g., E12, E26, E39).
- Prefocus and tubular lamp lampholders.
- Automotive lamp lampholders with tailored safety and interchangeability aspects.
- Specialized lampholders such as for photo-flash lamps, automotive lamps, and combined pairs.
Mounting and Connection Specifications
- Guidelines on mounting distances for combined and single lampholder sets.
- Standardized connector types and dimensions for ease of assembly.
- Precise location requirements of threaded components in relation to contacts.
Applications
IEC 60061-2 Amendment 42 is fundamental for manufacturers, designers, and testing laboratories involved in lamp and lighting device production. Its practical applications include:
- Manufacturing: Enables consistent production of lampholders to meet global interchangeability and safety expectations, facilitating interoperability in lighting systems.
