Abstract
IEC 60400:2008 states the technical and dimensional requirements for lampholders for tubular fluorescent lamps and for starterholders, and the methods of test to be used in determining the safety and the fit of the lamps in the lampholders and the starters in the starterholders. This seventh edition cancels and replaces the sixth edition (1999) and its Amendments 1 (2002) and 2 (2004). This seventh edition constitutes a technical revision. In this edition, information on lampholders intended to be used in applications where they are accessible in normal use (class II luminaires as well as class I luminaries) has been introduced, as well as requirements for contact-making to pins for single-capped fluorescent lamps, introduction of new fits in the text and Annex A, and requirements for shade holder rings have been adopted.
