IEC 61298-1:2026

IEC 61298-1:2026 specifies general methods and procedures for conducting tests and reporting on the functional and performance characteristics of process instrumentation except process measurement transmitters (PMT) which are standardized by the IEC 62828 series. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs and include analogue and digital devices. For devices that require special tests, this document can be used together with any product specific standard specifying special tests. This document covers general principles which apply to the IEC 61298 series.
This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Process measurement transmitters (PMT) have been removed from the scope of this standard.
