Overview
EN 60399:2004/A1:2008 (identical to IEC 60399:2004/A1:2008) is a European amendment that defines the barrel thread for lampholders with shade holder ring. The amendment introduces a clear scope, definitions and mandatory requirements for barrel threads used to retain shades and shade rings on lampholders. It was approved by CENELEC in 2008 and supplements the base EN 60399:2004 text.
Key Topics
- Scope and purpose
- Applies to lampholders designed with an external barrel thread that supports a shade ring and to the barrel threads of those shade rings.
- Definitions
- Clear terminology such as barrel thread (external thread on the outer shell of a lampholder) and shade ring (cylindrical component with internal thread to retain a shade).
- Mandatory vs. optional use
- Barrel threads specified in this standard are mandatory for general use except:
- For B15 and B22 lampholders, alternative barrel threads are allowed if they comply with Figure 8 of IEC 61184.
- Other special lampholders may use alternative barrel threads when the lampholder will be installed only by the luminaire or equipment manufacturer.
- Barrel threads specified in this standard are mandatory for general use except:
- Dimensional requirements and gauges
- The amendment instructs insertion of existing datasheets into the subclause covering dimensional requirements and gauges (datasheets define the physical tolerances and gauges used for conformity checks).
- Normative references
- The standard cross-references key lampholder and luminaire documents that are indispensable for application and safety assessment.
Applications
Who uses this standard and why:
- Lamp and lampholder manufacturers - to ensure mechanical compatibility and secure mounting of shades across products.
- Luminaire designers and manufacturers - to select lampholders and shade rings that meet interchangeability and safety expectations.
- Test laboratories and conformity assessors - to verify dimensional compliance using gauges and datasheets referenced by the standard.
- Compliance officers and procurement teams - to specify standardized barrel threads in product specifications and procurement contracts.
Practical benefits:
- Ensures interchangeability of shades and rings across products.
- Supports mechanical safety by standardizing thread geometry and gauges.
- Simplifies design and production by referencing accepted dimensional datasheets.
