24、us 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
25、 lampholders which are integral with a luminaire. It covers the requirements for the lampholder only. This part of IEC 60838 also covers lampholders integrated in an outer shell and dome similar to Edison screw lampholders. Such lampholders are further tested in accordance with the following subclau
26、ses of IEC 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. Lampholders designed with a barrel thread for shade holder rings should comply with IEC 60399. Requirements for lampholders for tubular fluorescent lamps, Edison screw lampholders and bayonet lamph
27、olders are covered by separate standards. 1.2 Normative references The following referenced documents are indispensable for the application of this document.

38、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 the

44、gories I, II, III and IV are used. a) Purpose of classification of impulse withstand categories Impulse withstand categories are to distinguish different degrees of availability of equipment with regard to required expectations on continuity of service and on an acceptable risk of failure. By select
45、ion of impulse withstand levels of equipment, insulation co-ordination can be achieved in the whole installation reducing the risk of failure to an acceptable level providing a basis for overvoltage control. A higher characteristic numeral of an impulse withstand category indicates a higher specific
46、 impulse withstand of the equipment and offers a wider choice of methods for overvoltage control. The concept of impulse withstand categories is used for equipment energized directly from the mains. b) Description of impulse withstand categories Equipment of impulse withstand category I is equipment
47、 which is intended to be connected to the fixed electrical installations of buildings. Protective means are taken outside the equipment either in the fixed installation or between the fixed installation and the equipment to limit transient overvoltages to the specific level. Equipment of impulse wit
48、hstand category II is equipment to be connected to the fixed electrical installations of buildings. Equipment of impulse withstand category III is equipment which is part of the fixed electrical installations and other equipment where a higher degree of availability is expected. Equipment of impulse
49、 withstand category IV is for use at or in the proximity of the origin of the electrical installations of buildings upstream of the main distribution board. 2.12 primary circuit a circuit which is directly connected to the AC mains supply. It includes, for example, the means for connection to the AC mains supply, the primary windings of transformers, motors and other
