: Edition 3.0 (Project oSIST prEN IEC 61298-2:2024) is currently in the "Enquiry" stage.
During test, the device's digital output (if present) must be monitored for:
: Evaluations of input/insulation resistance, dielectric strength, and power consumption (both electrical and pneumatic). iec 612982 new
Updated guidelines for measuring start-up and long-term drift to ensure devices maintain reliability over extended operation.
The most significant "new" development regarding IEC 61298-2 is its transition to a third edition. A Pre-Release Version (PRV) : Edition 3
The new framework improves how errors are calculated and presented. Accuracy metrics are broken down into distinct mathematical components to help R&D engineers target specific design issues. Metric Category Evaluation Methodology Representation
Technical specifications for new hardware tenders must cite the updated standard to guarantee the engineering documentation is valid. Sourcing and Compliance Documentation The most significant "new" development regarding IEC 61298-2
The standard distinguishes between these two phenomena, which often confuse engineers.

A device may maintain analog accuracy but fail digital communication. This is a common hidden failure mode in smart sensors.
The 2026 edition clarifies the boundaries of the standard more precisely than its predecessor.
