标准摘要
IEC 60838-1:2004+A1:2008+A2:2011 applies to lampholders of miscellaneous types intended for building-in (to be used with general purpose light sources, projection lamps, floodlighting lamps and street-lighting lamps with caps as listed in annex A) and the methods of test to be used in determining the safe use of lamps in lampholders. This part of IEC 60838 also covers lampholders which are integral with a luminaire. It covers the requirements for the lampholder only. The technical content is therefore identical to the base edition and its amendments and has been prepared for user convenience. It bears the edition number 4.2. A vertical line in the margin shows where the base publication has been modified by amendments 1 and 2. In this edition the new requirements for creepage distances and clearances have been adopted which are currently circulated by SC34D to amend the IEC 60598 family of luminaire standards. It also includes additional requirements regarding testing of lampholders for double-ended R7s/RX7s lamps. This consolidated version consists of the fourth edition (2004), its amendment 1 (2008) and its amendment 2 (2011). Therefore, no need to order amendments in addition to this publication.
