31、nvironment Classification of the environment Compatibility levels Part 3: Limits Emission limits Immunity limits (in so far as they do not fall under the responsibility of the product committees) Part 4: Testing and measurement techniques Measurement techniques Testing techniques Part 5: Installatio

32、n and mitigation guidelines Installation guidelines Mitigation methods and devices Part 6: Test set-up Part 9: Miscellaneous Each part is further subdivided into several parts, published either as international standards, as technical specifications or technical reports, some of which have already b

33、een published as sections. Others will be published with the part number followed by a dash and a second number identifying the subdivision (example: IEC 61000-6-1). This part is an international standard that establishes the required test procedures for using fully anechoic rooms for performing rad

34、iated immunity testing and radiated emission measurements. The main text of this standard provides all information that is common to both radiated emission measurements and immunity tests in a FAR (fully anechoic room). This includes the description of a FAR, a common set-up for equipment under test

35、 (EUT), and a harmonized validation/calibration procedure. The test methods described in this standard are based on the harmonized validation/calibration which verifies a FAR as a measurement system, including the room, antenna and associated cables simultaneously. The validation procedure determine

36、s a combined transducer factor for a FAR measurement system that is later applied to both emission measurements and immunity tests. If different sets of antennas and/or cables are used for emission measurements and immunity tests the validation/calibration process is performed twice. Annex A (normat

37、ive) provides the measurement procedure and any special considerations for performing radiated immunity tests. Annex B (normative) provides the measurement procedure and any special considerations for performing radiated emission measurements. BS EN 61000-4-22:201161000-4-22 IEC:2010 7 Annex C (info

38、rmative) provides background on the system transducer factor and simultaneous emissions/immunity validation method. Annex D (informative) provides guidance for calculation of the uncertainty of measurement results obtained using a FAR and instrumentation in accordance with ISO/IEC Guide 98-3 41). _

40、mmunity tests and emission measurements for electric and/or electronic equipment. Only radiated phenomena are considered. It establishes the required test procedures for using fully anechoic rooms for performing radiated immunity testing and radiated emission measurements. NOTE In accordance with IE

41、C Guide 107 1, IEC 61000-4-22 is a basic EMC publication for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of the EMC standards. TC 77 and CISPR and their sub-committees are prepared to cooperate with product commit

42、tees in the determination of the value of particular EMC tests for specific products. This part establishes a common validation procedure, equipment under test (EUT) set-up requirements, and measurement methods for fully anechoic rooms (FARs) when both radiated electromagnetic emission measurements

43、and radiated electromagnetic immunity tests will be performed in the same FAR. As a basic measurement standard, this part of IEC 61000 does not intend to specify the test levels or emission limits to be applied to particular apparatus or system(s). Its main goal is to provide general measurement pro

44、cedures to all concerned product committees of IEC or CISPR. Specific product requirements and test conditions are defined by the responsible product committees. The methods described in this standard are appropriate for radiated emission measurements and immunity tests in the frequency range of 30

45、MHz to 18 GHz. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
