This Part 2-9 is intended to be used in conjunction with EN 61558-1:1997. This Part 2-9 supplements or modifies the corresponding clauses in EN 61558-1, so as to convert that publication into the European Standard: Particular requirements for transformers for class III handlamps for tungsten filament lamps. When a particular subclause of Part 1 is not mentioned in this Part 2-9, that subclause applies as far as is reasonable. Where this Part 2-9 states “addition”, “modification” or “replacement”, the relevant text of Part 1 is to be adapted accordingly. In this standard, the following print types are used: - requirements proper: in roman type; - test specifications: in italic type; - explanatory matter: in smaller roman type. In the text of this standard the words in bold are defined in clause 3. Subclauses which are additional to those in Part 1 are numbered starting from 101. __________ Endorsement notice The text of the International Standard IEC 61558-2-9:2002 was approved by CENELEC as a European Standard without any modification. __________

61558-2-9  IEC:2002– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________SAFETY OF POWER TRANSFORMERS, POWER SUPPLY UNITSAND SIMILAR PRODUCTS –Part 2-9: Particular requirements for transformersfor class III handlamps for tungsten filament lampsFOREWORD1)The IEC (International Electrotechnical Commission) is a world-wide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardisation (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patents rights. The IEC shall not be held responsible for identifying any or all such patents rights.International Standard IEC 61558-2-9 has been prepared by IEC technical committee 96: Smallpower transformers, reactors, supply units and similar products.It has the status of a group safety publication in accordance with IEC Guide 104.The text of this standard is based upon the following documents:FDISReport on voting96/184/FDIS96/185/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.This Part 2-9 is intended to be used in conjunction with IEC 61558-1. It was established on thebasis of the first edition (1997) of that standard and its amendment 1 (1998).This Part 2-9 supplements or modifies the corresponding clauses in IEC 61558-1, so as toconvert that publication into the IEC standard: Particular requirements for transformers forclass III handlamps for tungsten filament lamps.
