This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Modification of scope to address other devices in addition to RCDs; - Modification of Clause 8 so that IEC 62873-3-3 can be referred to by other product standards in addition to those for RCDs; - Modification of 9.1 so that IEC 62873-3-3 can be referred to by other product standards in addition to those for RCDs.
