IEC 61547:2020 pdf free download – Equipment for general lighting purposes- EMC immunity requirements
Tests are applied to the relevant ports of the equipment as indicated in the respective clauses.For the purposes of this document,DC power ports for supplying regulating controls areconsidered to be signal ports. Tests shall be conducted in a well-defined and reproduciblemanner. Tests shall be carried out as single tests in sequence.The sequence of testing isoptional.
lt may be determined from consideration of the electrical characteristics and usage ofparticular equipment that some of the tests are inappropriate and therefore unnecessary. Insuch cases it is required that the decision not to test be recorded in the test report.
The description of the test, the test generator, the test methods and the test set-up are givenin the basic standards, which are referred to in the relevant clauses.
In this document, in most cases, the selected test levels are based on level 2 values as givenin the basic test and measurement immunity standards; these standards are referred to in therespective clauses.
Further explanation on the methodology and criteria why certain test phenomena, test levelsand performance criteria are chosen for certain types of lighting equipment are given inAnnex A.
Modules are tested as any other lighting equipment but shall be mounted in a representativehost and the port(s) of the module being assessed shall be terminated accordingly. Arepresentative host is a reference luminaire or reference system that enables properfunctioning of the EUT. The functions of the host that are specific to the module beingassessed shall be exercised during the tests. The host shall also incorporate essential EMlprotection means or mitigation measures if these are explicitly specified by the manufacturerfor application of such a module. A representative host shall also include the safety Class l orll features,whichever is applicable. lf the module is tested in a host, the correct functioning ofthe combination shall be verified prior to the application of the disturbance. A detaileddescription of the host shall be given in the test report.Self-ballasted lamps shall be tested inhosts (reference luminaires) as specified in CISPR 15:2018,Annex A.
For modules, the length of the cables between the module and other devices that are part ofthe host shall be 3 m unless the manufacturer specifies another length.
NOTE 1 Depending on the type of lighting equipment,for ESD tests deviating requirements for usingrepresentative hosts can apply (see 5.2.2).
NOTE 2 The word module in this document refers to end-user replaceable modules as defined in 3.5.
5.2.1General
Electrostatic discharge tests shall be carried out according to lEC 61000-4-2:2008,with testlevels as given in Table 1 for all lighting equipment and additional test levels as given in 5.2.3for road and street lighting equipment. Contact discharge is the preferred test method.Twentydischarges (10 with positive and 10 with negative polarity) shall be applied on eachaccessible metallic part of the enclosure,including terminals for connecting end-userreplaceable modules. Air discharges shall be used where contact discharges cannot beapplied. In addition, discharges shall be applied on the horizontal and vertical coupling planes,as specified in lEC61000-4-2:2008.
5.2.3Road and street lighting equipment
In addition to the requirements in 5.2.2, road and street lighting equipment shall be tested forair discharge at ±15 kV and for contact discharge at ±8 kV. This is to simulate thephenomenon of static charging during thunderstorms.
End-user replaceable modules that are accessible during installation and maintenance shallbe tested according to 5.2.2.The term “road and street lighting equipment” signifies thecombination of the module(s) and the luminaire as installed in the final application.
