Scope
This standard is designed to ensure that the rated voltage does not exceed 440 V AC, and is mainly used for electromagnetic compatibility (EMC) of residual current protection devices to protect the human body from electric shock This standard applies to environmental conditions that occur in equipment connected to low-voltage public power grids or similar line facilities. This standard can also provide guidance for ensuring the EMC performance of other products used for safety purposes, or products containing electronic circuits with high work continuity requirements For EMC testing requirements not included in product standards, reference should be made to this product family standard
