Recently, CENELEC has published a revised version of the voltage flicker test standard EN 61000-3-3: 2013+ A2:2021. And then, a corrigendum version which EN 61000-3-3:2013+ A2:2021 +AC: 2022 was published . The following are the major changes in the two versions.
---------------------------Updated Content---------------------------
EN 61000-3-3: 2013+A2: 2021
The main changes are to revise or add test conditions for specific equipment in Annex A:
The above products will need to be re-tested if the report needs to be updated to the new standard version.
EN 61000-3-3: 2013+A2: 2021+AC: 2022
The sixth paragraph of "A.16 coffee makers and tea makers" is corrected:
Take [Plt shall not be evaluated] out of paragraph 6 to form a separate paragraph 7 to clarify that the equipment described in A.16 does not require evaluation of Plt
---------------------------OJ HS?J---------------------------
The (dow) time given in the A2 version of the standard is 2024-11-05, this version has not yet in OJ
Note: The OJ HS for voltage flicker is currently EN 61000-3-3:2013
