IEC 60770 is specifically for transmitters, whereas IEC 61298-2 is a more general standard for all process instruments.
The exact hardware revision, firmware build version, and calibrated span settings of the device.
IEC 61298-2 outlines general methods for evaluating the performance of process measurement and control devices under reference conditions, emphasizing accuracy metrics like hysteresis and repeatability. A compliant report must document specific test results, such as measurement cycles and drift analysis, often utilizing structures from the IEC 61298 series.

Any system defined by a distinct, predictable input-to-output relationship. 2. Benchmark Testing Framework
The "story" begins in a controlled environment. Before a device is tested in the harsh real world, it must be evaluated under "reference conditions"—ideal temperatures, pressures, and power levels—to establish its baseline accuracy. IEC 60770 is specifically for transmitters, whereas IEC
The IEC regularly revises standards to keep pace with technological changes. The entire IEC 61298 series is currently undergoing its third major revision. Key updates include:
The current focus, establishing "best-case" performance. A compliant report must document specific test results,
The IEC 61298-2 standard is engineered for broad compatibility across the industrial automation landscape. It applies to any device that operates via a defined —the mathematical or operational relationship mapping physical or electrical input variables directly to output variables. Types of Covered Devices
The standard, titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions," is part of a larger series designed to ensure reliable, repeatable, and comparable measurement results across industrial automation.
