IEC 60838-1 pdf download – Miscellaneous lampholders – Part 1: General requirements and tests
1General1.1 Scope
This part of lEC 60838 applies to lampholders of miscellaneous types intended for building-in(to be used with general purpose light sources，projection lamps，floodlighting lamps andstreet-lighting lamps with caps as listed in annex A) and the methods of test to be used indetermining the safe use of lamps in lampholders.
This part of lEC 60838 also covers lampholders which are integral with a luminaire. lt coversthe requirements for the lampholder only.
This part of lEC 60838 also covers lampholders integrated in an outer shell and dome similarto Edison screw lampholders. Such lampholders are further tested in accordance with thefollowing subclauses of lEC 60238:8.4;8.5;8.6;9.3;10.7;11; 12.2;12.5;12.6;12.7;13;15.3;15.4;15.5 and 15.9.
Requirements for lampholders for tubular fluorescent lamps，Edison screw lampholders andbayonet lampholders are covered by separate standards.

Definitions
For the purpose of this International Standard, the following definitions apply.
2.1
rated voltage
the voltage declared by the manufacturer to indicate the highest working voltage for which thelampholder is intended
2.2
working voltage
the highest r.m.s. voltage that may occur across any insulation,transients being disregarded,both when the lamp is operating under normal conditions and when the lamp is removed
2.3
rated current
the current declared by the manufacturer to indicate the highest current for which thelampholder is intended
2.4
lampholder for building-in
a lampholder designed to be built into a luminaire,an additional enclosure or the like
2.4.1
unenclosed lampholder
a lampholder for building-in so designed that it requires additional means，for exampleenclosures,to meet the requirements of this standard with regard to protection againstelectric shock
2.4.2
enclosed lampholder
a lampholder for building-in so designed that it fulfils on its own the requirements of thisstandard with regard to protection against electric shock
