| Note in Official Journal: | |
| Subject of the standard: | IEC 61557-4:2019 specifies the requirements applicable to equipment for measuring the resistance of earth conductors, protective earth conductors and conductors for equipotential bonding, including their connections and terminals, with an indication of the measured value or an indication of the limits. IEC 61557-4:2019 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) complement to the measurement category in Clause 4; b) correction of the equation for operating uncertainty; c) complement to the requirements for measuring with DC; d) alignment of the structure with that of the whole IEC 61557 series. |
