This part of IEC 61557 specifies the general requirements applicable to measuring and monitoring equipment for testing the electrical safety in low-voltage distribution systems with nominal voltages up to 1 000 V AC and 1 500 V DC.
When measuring equipment or measuring installations involve measurement tasks of various
measuring equipment covered by this series of standards, then the part of this series relevant to each of the measurement tasks is applicable.
NOTE The term "measuring equipment" will hereafter be used to designate "testing, measuring and monitoring equipment".
Other parts of IEC 61557 can specify additional requirements or deviations.
This document does not cover functional safety or cybersecurity.
