Electromagnetic compatibility - Product family standard for audio, video, audio-visual and entertainment lighting control apparatus for professional use - Part 2: Immunity

This European Standard for EMC immunity requirements applies to professional audio, video, audio-visual and entertainment lighting control apparatus as defined in 3.6 intended for use in the environments described in Clause 4. This includes the digital apparatus defined in 3.5 and sub-assemblies, see 7.4. Disturbances in the frequency range 0 Hz to 400 GHz are covered, but requirements are not established over the whole of that range. NOTE 1 In Annex C, information is included on infra-red radiation in the wavelength range 0,7 µm to 1,6 µm. The objective of this standard is to define the immunity test requirements, test signals, performance criteria and test methods for apparatus defined in the scope, in relation to electromagnetic immunity to continuous and transient conducted and radiated electromagnetic disturbances including electrostatic discharges. These test requirements represent essential electromagnetic compatibility requirements. Fault conditions of source or victim apparatus are not taken into account. Apparatus as defined in 3.4, 3.5 and 3.6 may be operated with any source of power. NOTE 2 Sources of power may include, for example: the public low-voltage supply; private supplies with similar characteristics; a d.c. source provided specifically for the apparatus; batteries internal to the apparatus; stand-by generators. Some standards may not apply to private low-voltage supplies. NOTE 3 If it is intended to use a hand-held transmitter in proximity, additional mitigation measures may have to be employed to increase the electromagnetic immunity further, beyond the specified limits. This European Standard does not apply to – consumer apparatus, – apparatus specifically designed for security systems, – apparatus designed to radiate electromagnetic energy for radio communications purposes.

Elektromagnetna združljivost - Standard za družino izdelkov za regulacijo avdio, video, avdiovizualnih in osvetlitvenih zabaviščnih naprav za profesionalno uporabo - 2. del: Odpornost proti motnjam

Ta evropski standard za zahteve glede odpornosti EMC velja za profesionalne avdio, video, avdiovizualne in osvetlitvene zabaviščne naprave, kot so opredeljene v točki 3.6, namenjene za uporabo v okoljih, opisnih v Klavzuli 4. Vključuje digitalne naprave, opredeljene v točki 3.5., in podsklope (glej točko 7.4). Motnje v frekvenčnem razponu od 0 Hz do 400 GHz so zajete, vendar zahteve niso vzpostavljene za ta celotni razpon. OPOMBA 1: V Dodatku C so vključene informacije o infrardečem sevanju v razponu valovnih dolžin od 0,7 do 1,6 µm. Cilj tega standarda je opredeliti zahteve za preskušanje odpornosti, preskusne signale, merila zmogljivosti in preskusne metode za naprave, opredeljene na področju uporabe, glede na elektromagnetno odpornost proti neprekinjenim, začasnim in vodenim ter sevanim elektromagnetnim motnjam, vključno z elektrostatičnimi razelektritvami. Te preskusne zahteve predstavljajo bistvene zahteve za elektromagnetno združljivost. Okvare vira ali prizadete naprave niso upoštevane. Naprave, opredeljene v točkah 3.4, 3.5 in 3.6, lahko napaja kakršen koli vir energije.

EN 55103-2:2009 - 12 - 7 Testing 7.1 Performance criteria The variety and diversity of the apparatus within the scope of this standard make it difficult to define precise criteria for the evaluation of the immunity test results. Guidance as to the characteristics of apparatus which may be degraded by inadequate immunity is given in Annex D. Apparatus shall not become dangerous or unsafe as a result of the application of the tests defined in this standard. The manufacturer shall provide details, which shall be noted in the test report, of any degradation of performance or loss of function, during or as a consequence of each test, based on the following criteria: Performance criterion A: The apparatus shall continue to operate as intended. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, then either of these may be derived from the product description and documentation (including leaflets and advertising) and what the user may reasonably expect from the apparatus if used as intended. Performance criterion B: The apparatus shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended. The performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is, however, allowed. No change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, then either of these may be derived from the product description and documentation (including leaflets and advertising) and what the user may reasonably expect from the apparatus if used as intended. Performance criterion C: Temporary loss of function is allowed, provided that normal function is automatically restored when the test stimulus is removed, or can be restored by operation of the controls. It is permissible for the manufacturer to specify loss of performance by using the five point impairment scale defined in ITU/R Recommendation 500-4 or 562-3. NOTE Examples and further information are given in Annex D. 7.2 General In this standard, reference is made to reproducible laboratory conditions which may not always accurately represent conditions found in practice. It may be determined from consideration of the electrical characteristics and usage of a particular apparatus that some tests are inappropriate and therefore unnecessary. In such a case the decision and justification not to test shall be recorded in the test report. The tests shall be made in the least immune operating mode for the phenomenon being investigated in accordance with the manufacturer's instructions. The configuration of the test sample shall be varied to achieve minimum immunity. If the apparatus is part of a system, or can be connected to auxiliary apparatus, then the apparatus shall be tested while connected to the minimum configuration of auxiliary apparatus necessary to exercise the ports. In cases where a manufacturer's specification specifically requires external protection devices or measures which are clearly specified in the user's manual, then the test requirements of this standard shall be applied with the external protection devices or measures in place. SIST EN 55103-2:2010

- 13 - EN 55103-2:2009 The configuration and mode of operation during testing shall be precisely noted in the test report. It is not always possible to test every function of the apparatus; in such cases the most critical mode of operation shall be selected. Where applicable, test programs and software shall be chosen so as to exercise all normal modes of operation of the apparatus under test. The use of special exercising software is permitted provided that it can be shown that the apparatus under test is being comprehensively exercised in its normal operating modes. Tests shall be performed in well-defined and reproducible conditions for each type of test stimulus. The tests shall be carried out one by one in sequence
