The newest version of IEC 61298-2, titled "Process measurement and control devices – General methods and procedures for evaluating performance – Part 2: Tests under reference conditions", is currently under development as Edition 3.0. It has a forecasted publication date of June 5, 2026.
Data centre and high-speed data transmission: The standard addresses the specific needs of data centres and high-speed data transmission applications, including:
IEC 61282-2 specifically focuses on indoor optical fibre cables, which are used in buildings, data centres, and other indoor environments. The standard covers the requirements for: iec 612982 new
: The new draft specifies that it covers both analogue and digital instrumentation, but explicitly excludes Process Measurement Transmitters (PMT) , which are now covered by the Target Users The newest version of IEC 61298-2 , titled
3. Determination of Intrinsic Errors
IEC 61298-2 provides the procedures to determine the "baseline" accuracy of a device. This includes: Data centre and high-speed data transmission : The
- Old method (Sinusoidal):
F = A * sin(2πft) – This finds mechanical resonance frequencies. It tells you if a screw will come loose at 55 Hz.
- New method (Random PSD):
PSD = (Grms^2) / (Δf) – This simulates real-world fatigue. A pump doesn't vibrate at one frequency; it vibrates across a spectrum simultaneously.
Purpose: It ensures that tests are conducted under standardized reference conditions, allowing for reliable, repeatable, and comparable results across the industry.
