IEC 61000-3-2:2020 pdf free download – Electromagnetic compatibility (EMC)
3.14 stand-by mode
non-operational,low power consumption mode (usually indicated in some way on theequipment) that can persist for an indefinite time
3.15 repeatability
<results of measurements> closeness of the agreement between the results of measurementsof harmonic currents on the same equipment under test，carried out with the same testsystem, at the same location, under identical test conditions
3.16 reproducibility
<results of measurements> closeness of the agreement between the results of measurementsof harmonic currents on the same equipment under test，carried out with different testsystems under conditions of measurement intended to be the same in each case
Note 1 to entry: The test system and test conditions are assumed to fulfil all normative requirements in theapplicable standards.
3.17 variability
<results of measurements> closeness of the agreement between the results of measurementsof harmonic currents on different samples of the same type of equipment under test, havingno intentional differences,carried out with different test systems under conditions ofmeasurement intended to be the same in each case
Note 1 to entry: The test system and test conditions are assumed to fulfil all normative requirements in theapplicable standards.
Note 2 to entry: In the context of this document, the meaning of the terms can be summarized as follows:
3.19 lighting control gear
unit inserted between the power supply and at least one light source,which serves to supplythe light source(s) with the voltage and/or-current required for its (their) intended operation,and which can consist of one or more separate components.
Note 1 to entry: The lighting control gear can include means for igniting, dimming, correcting the power factor andsuppressing radio interference,and further control functions.
Note 2 to entry: The lighting control gear can be partly or totally integrated in the light source.
Note 3 to entry: For the purposes of this document, independent phase control dimmers as defined in 3.23 and3.24 are not considered to be lighting control gear.
3.20 digital load side transmission lighting control deviceDLT control device
device to control lighting parameters of electronic lighting equipment, such as light level andlight colour，using data transmission over its load side mains wiring in accordance withEC 62756-1:2015
Note 1 to entry: A DLT control device is wired like a phase control dimmer, but does not directly make the supplypower delivered to the connected dedicated lighting equipment vary. It transmits digital signals over the powercable on the load side to the dedicated lighting equipment,which contains means for receiving and interpretingcontrol signals as well as built-in means for dimming, colour variation and other operating features.
Note 2 to entry: This note applies to the French language only.
4General
The objective of this document is to set limits for harmonic emissions of equipment within itsscope, so that,with due allowance for the emissions from other equipment, compliance withthe limits ensures that harmonic disturbance levels do not exceed the compatibility levelsdefined in lEC 61000-2-2.
Professional equipment that does not comply with the requirements of this document can bepermitted to be connected to certain types of low voltage supplies, if the instruction manualcontains a requirement to ask the supply utility for permission to connect.Recommendationsconcerning this aspect are contained in lEC 61000-3-12.
