26、2015 IEC 2015 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ PROGRAMMABLE COMPONENTS IN ELECTRONIC LAMP CONTROLGEAR GENERAL AND SAFETY REQUIREMENTS FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical co
27、mmittees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Techni
28、cal Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, government
29、al and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agr
30、eements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use
31、 and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promo
32、te international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indica
33、ted in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6)
34、All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage
35、 or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this public
36、ation. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all suc
37、h patent rights. International Standard IEC 62733 has been prepared by subcommittee 34C: Auxiliaries for lamps, of IEC technical committee 34: Lamps and related equipment. The text of this standard is based on the following documents: FDIS Report on voting 34C/1140/FDIS 34C/1156/RVD Full information

BS EN 62733:2015 6 IEC 62733:2015 IEC 2015 INTRODUCTION This International Standard provides safety requirements and test methods for programmable components
41、when in electronic lamp controlgear. It provides additional safety requirements for electronic lamp controlgear containing programmable components to the requirements of IEC 61347 series. In general, the two means of protection safety principle is used for protection against hazards such as electric
42、 shock. Consequently one single fault condition or abnormal operation of the electrical equipment will not lead to a hazardous situation. Until recent technology, two means of protection have been realized in traditional hardware. Examples are the provision of basic insulation and supplementary insu
43、lation between hazardous live parts and accessible parts, and provision of basic insulation combined by disconnection of the mains supply by a fuse. Nowadays however programmable components (with embedded software) may be used as a measure to provide safety under normal conditions, single fault cond
44、itions and/or abnormal operation. Since the traditional lighting standards do not provide requirements for programmable components, this standard has been drawn up. This standard recognizes the internationally accepted level of protection against hazards such as electrical, mechanical, thermal, fire
45、 and radiation of appliances when operated as in normal use taking into account the manufacturers instructions. It also covers conditions for electromagnetic phenomena that can be expected in practice with influence on the operation of the programmable component, for taking into account the way this
46、 can affect the safe operation of the electronic lamp controlgear. This first edition is based upon IEC 60730-1:2010 and IEC 60335-1:2010 and adapted for electronic lamp controlgear NOTE The terms and definitions and Tables A.1 and A.2 respectively of this standard are equivalent to terms and defini
47、tions and Table R.1 and R.2 of IEC 60335-1:2010, and equivalent terms and definitions and Table H.1 (class B and class C software) of IEC 60730-1:2010.

48、ational Standard provides general and safety requirements for programmable components used in products covered by IEC 61347. The requirements of this standard are only applicable to the programmable components (including its embedded software) in the electronic lamp controlgear. For other electric/e
49、lectronic circuits and their components in the electronic lamp controlgear, the requirements of IEC 61347 series apply. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
