: Ambient temperature, relative humidity, atmospheric pressure, and power supply voltage must be locked within the standard's strict reference limits before testing begins.

The goal is to determine the of the device (its accuracy, repeatability, hysteresis, etc.) without interference from real-world factors like temperature variation, vibration, or electromagnetic noise (those are covered in other parts of the IEC 61298 series).

Analogue and digital industrial devices, excluding certain Process Measurement Transmitters (PMT) covered by the IEC 62828 series.

1. Scope Exclusion of Process Measurement Transmitters (PMT)

The release of IEC 61298-2 Edition 3.0 is a pivotal step in modernizing industry standards. The separation of PMTs into their own dedicated series and the simultaneous revision of all other parts of IEC 61298 (Parts 1, 3, and 4) will create a clearer, more efficient framework for evaluating the performance of process measurement and control devices.

: Documenting how performance might shift at start-up or over long-term use. Where to Find it

For end users, this means higher upfront costs, but drastically lower unplanned downtime due to vibration-induced HART communication loss or condensation shorts. For manufacturers, it signals the end of "cheap and cheerful" instruments that barely passed the old tests.

Introduces more realistic operating conditions and emphasizes economic aspects, such as choosing test points that balance result relevance with testing costs. Latest Draft: prEN IEC 61298-1:2024 .

In some regulatory contexts (e.g., EU harmonized standards for CE marking), it may be required. In general, it is a voluntary international standard unless referenced by regulations or product-specific standards.

The previous version, IEC 61298-2:2008 , served the automation industry reliably for nearly two decades. However, the rise of Industry 4.0 necessitated a thorough technical overhaul. 1. Explicit Exclusions for Process Measurement Transmitters
