11、The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical
12、and electronic fields. To 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
13、committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organizati
14、on for Standardization (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 comm
15、ittee has representation from all interested 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 i
16、s 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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and
17、regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and
18、, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 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
19、agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage 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
20、of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited 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 so
21、me 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 such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication
22、 of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 62696, which is a technical report, has been prepared by 34D: Luminaires, of IEC technical committee 34: Lamps and related equ
23、ipment. The text of this technical report is based on the following documents: Enquiry draft Report on voting 34D/965/DTR 34D/1001/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been
24、 drafted in accordance with the ISO/IEC Directives, Part 2. TR 62696 IEC:2011(E) 3 The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publicatio
25、n. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version may be issued at a later date. 4 TR 62696 IEC:2011(E) INTRODUCTION The IK code detailing resistance to mechanical impact performance, given in IEC 62262, places responsibil
26、ity on product standard committees to specify: definition of enclosure; impact test equipment to be used; number of samples to be tested; conditions for test sample mounting; any preconditioning of the test sample; whether to be tested energised; whether to be tested with moving parts in motion; the
27、 number of impacts and their points of application. Other aspects particular to consideration of luminaires may also be appropriate. For example: acceptable/non-acceptable damage following impact; level of luminaire performance and operation to be maintained following impact. TR 62696 IEC:2011(E) 5
28、LUMINAIRES APPLICATION OF THE IK CODE IEC 62262 1 Scope This Technical report covers the testing and classification of luminaires according to IEC 62262. The application of an IK rating to a luminaire is considered to be a performance issue and is not directly related to the safety provisions of IEC
29、 60598 standards covering luminaire safety. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any ame
30、ndments) applies. IEC 60068-2-75, Environmental Testing Part 2-75: Tests Eh: Hammer Tests IEC 60598 (all parts) Luminaires IEC 60598-1, Luminaires General requirements and tests IEC 62262, Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK c
31、ode) 3 Conditions of testing 3.1 In general, testing is conducted in accordance with IEC 62262, having regard to the general test conditions specified by IEC 60598-1, Subclause 4.13, and the following conditions which are specific for the IK testing and rating of luminaires. 3.2 Impacts should not b
32、e applied through openings in the luminaire enclosure with an area less than 64 cm. NOTE For example, no impact should be applied through the individual openings in optical controls (louvers) if their size is less than 64 cm. 3.3 Luminaires should be tested fully assembled and installed for use. Lum
33、inaires for ceiling or wall mounting should be mounted on a rigid wooden board. Suspended luminaires should be tested as in normal use, with the minimum suspension length detailed by the manufacturers instructions. Luminaires to be installed on a pole, with or without a mast arm, should be installed
34、 on a rigid portion of the pole. Floor mounted luminaires should be tested in a suitable rigid structure to simulate normal use. 6 TR 62696 IEC:2011(E) 3.4 Luminaires should not to be energised during test and no preconditioning of the luminaire sample is required. 3.5 Testing should be conducted on
35、 a single luminaire sample unless the results of impact testing of other areas of the luminaire could influence assessment of the result. Three impact blows should be applied to the point(s) of the luminaire considered to be the weakest. 3.6 Impact testing should be conducted using striking elements
36、 with head radius and material type as specified by IEC 60068-2-75. Spring hammer apparatus should be used for ratings up to and including IK06. For ratings IK07 and above, the use of pendulum or vertical hammer apparatus is acceptable, as most appropriate for the luminaire design and its intended i
37、nstallation. 3.7 Impact testing should be conducted with the luminaire in its intended mounting orientation whenever this is possible, and when this could affect the outcome of the test (e.g. for assessment of mounting surface fixing security). When impact testing of a ceiling-mounted luminaire is r
38、equired from below the luminaire, and this is impractical, the luminaire may be rotated 90 (to a wall mounted position) for the purposes of this testing. 3.8 In cases where it may be impossible to carry out the impact test due to the luminaire construction, it is acceptable to use a specially-prepar
39、ed luminaire to perform the test. For this situation, the modification should not impair the mechanical strength characteristics of the luminaire. 4 Conditions of acceptance 4.1 Safety of the luminaire is to be maintained as per the criteria given in IEC 60598-1, Subclause 4.13. Furthermore, the fix
40、ings of the luminaire to the mounting surface should remain secure. Non safety critical damage to the luminaire enclosure and optics is accepted, but no parts of the luminaire should become detached. Acceptance is checked by visual inspection, and test/measurement where required. 4.2 Protection of t
41、he light source should be provided and basic functioning of the luminaire should be maintained. Acceptance is checked by visual inspection and by operation of the luminaire following the test. _ INTERNATIONAL ELECTROTECHNICAL COMMISSION 3, rue de Varemb PO Box 131 CH-1211 Geneva 20 Switzerland Tel: + 41 22 919 02 11 Fax: + 41 22 919 03 00 infoiec.ch www.iec.ch
