    25、technical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote interna-tional co-operation on all questions concerning standardization in the electrical and electronic fields. T

    26、o this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC Nati

    27、onal Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organiza-tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or-ganization for Standardization

    28、(ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representatio

    29、n from all inter-ested IEC National Committees. 3) IEC Publications have the form of recommendations for international use 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

    30、 be held responsible for the way in which they are used or for any misinter-pretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications

    31、. Any divergence be-tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equip-ment declared to be in conformity with an IEC

    32、Publication. 6) 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,

    33、 property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and ex-penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-tions. 8) Attention is drawn to the Normative references ci

    34、ted in this publication. 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 pat-ent rights. IEC shall not be held responsible for identif

    35、ying any or all such patent rights. The International Standard IEC 62471 has been submitted by the International Commission on Illumi-nation (CIE) and has been processed through IEC technical committee 76: Optical radiation safety and laser equipment This standard was prepared as Standard CIE S 009:

    36、2002 by the International Commission on Illumination. It was submitted to the IEC National Committees for voting under the Fast Track Procedure as the following documents: FDIS Report on voting 76/340/FDIS 76/343/RVD Full information on the voting for the approval of this standard can be found in th

    37、e report on voting indicated in the above table.

The committee has decided that the contents of this publicatio

    38、n will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. The International Commission

    39、 on Illumination (abbreviated as CIE from its French title) is an organization devoted to international cooperation and exchange of information among its mem-ber countries on all matters relating to the science and art of lighting. Foreword of the International Commission on Illumination (CIE) Stand

    40、ards produced by the Commission Internationale de lEclairage (CIE) are a concise documenta-tion of data defining aspects of light and lighting, for which international harmony requires such unique definition. CIE Standards are therefore a primary source of internationally accepted and agreed data, w

    41、hich can be taken, essentially unaltered, into universal standard systems. The CIE undertook a major review of the official recommendations on photobiological effects, their dose relationships and measurement. Based on the guidelines given by the International Commission on Non-Ionising Radiation Pr

    42、otection (ICNIRP), the CIE undertook to apply these guidelines to lamps and lamp systems. The present standard describes present day knowledge of the subject but does not ab-solve those carrying out experiments with humans from their responsibility for the safety and well being of the subjects invol

    43、ved. This Standard has been prepared by CIE Technical Committee 6-47, “Photobiological Lamp Safety Standard“, and was approved by the National Committees of the CIE. During the preparation of the standard IEC TC34 co-operated with CIE TC 6-47 through the participation of a number of their mem-bers.

    44、NOTE CIE kindly acknowledges the consent of the Illuminating Engineering Society of North America who permit-ted to use extensive parts of the documents ANSI/IESNA RP-27.1. “Photobiological Safety for Lamps and Lamp Systems General Requirements“, ANSI/IESNA RP-27.2. “Photobiological Safety for Lamps

    45、 and Lamp Systems Measurement Systems - Measurement Techniques“ and ANSI/IESNA RP-27.3. “Photobiological Safety for Lamps and Lamp Systems Risk Group Classification and Labeling“ as much of the basis for this standard.

    47、large quantities and became commonplace in an era when industry-wide safety standards were not the norm. The evaluation and control of optical radiation hazards from lamps and lamp systems is a far more complicated subject than similar tasks for a single-wavelength laser system. The required radiome

    48、tric measurements are quite involved, for they do not deal with the simple optics of a point source, but rather with an extended source that may or may not be altered by diffusers or projection optics. Also the wavelength distribution of the lamp may be altered by ancillary optical elements, diffuse

    49、rs, lenses, and the like, as well as variations in operating conditions. To evaluate a broad-band optical source, such as an arc lamp, an incandescent lamp, a fluorescent lamp, an array of lamps or a lamp system, it is first necessary to determine the spectral distribution of optical radiation emitted from the source at the point or points of nearest human access. This accessible emission spectral distribution of interest for a lighting system may differ from that actually being e
