This second edition replaces and cancels the first edition published in 1997. It constitutes a technical revision. The following changes were made with respect to the previous edition: a) revision of the definitions; b) addition of influence quantities E9 and E10; c) the subclause on Electromagnetic compatibility was complemented; d) inclusion of performance monitoring devices in the introduction; e) addition of new requirements for operating instructions.
