Specifies the requirements for measuring equipment applied to the testing of the effectiveness of protective measures by regular disconnections of residual current protective devices (RCD) in TT, TN and IT systems. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision. The following changes were made with respect to the previous edition (1997): a) title and scope complemented; b) definitions complemented; c) revision of requirements; d) "tripping tests" and "non-tripping tests" subclauses complemented; e) markings complemented; f) addition of Annex A.
