The core objective of Part 2 is isolating the native behavior of a device. To prevent external factors from skewing accuracy data, tests must take place in an environment where all ambient and operational metrics are precisely maintained.
Industrial environments require rapid real-time corrections. Static accuracy alone does not ensure a stable system.
IEC 61298-2 , titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions," provides a standardized framework for evaluating the performance of industrial instrumentation. It ensures that performance data for analog and digital devices is reliable and comparable by testing them under controlled, ideal conditions. IEC Webstore Key Evaluation Areas iec 612982
The most significant change in the 3rd Edition is the removal of Process Measurement Transmitters (PMT) from the scope of IEC 61298. Moving forward, these devices will be covered by a separate and more specific standard series, , which addresses reference conditions and testing procedures for transmitters.
Industrial environments expose hardware to fluctuating temperatures, vibration, and electromagnetic interference. To determine an instrument's true capability, engineers must isolate its performance from these external variables. This is where IEC 61298-2 plays a foundational role. Primary Purpose The core objective of Part 2 is isolating
Implementing IEC 61298-2 offers immediate advantages across the entire automation supply chain:
Utilizing IEC 61298-2 offers several benefits for manufacturers and users: Static accuracy alone does not ensure a stable system
Confirms high electrical isolation to protect data lines from high-voltage spikes.
The IEC 61298 standard is essential for several reasons:
