The Dawn of a New Era in Process Instrumentation: A Deep Dive into the New IEC 612982-2 Revision

For decades, industrial process control has relied on a silent backbone of standards. Among these, the IEC 61298 series has been the gold standard for testing and evaluating the performance of process measurement instruments. However, with the recent release of the IEC 612982 new revision (formally IEC 61298-2:2025), the landscape of industrial calibration, vibration testing, and environmental simulation has shifted dramatically.

If you are a control systems engineer, a plant manager, or an instrumentation technician, understanding what is "new" in IEC 61298-2 is not just an academic exercise—it is a regulatory and operational necessity. This article unpacks the most critical changes, how they affect your legacy equipment, and why the 2025 update is being called the most significant overhaul in 15 years. iec 612982 new

Part 3: How the New IEC 61298-2 Impacts Different Industries

Who Should Use This Standard?

• Instrument manufacturers – To verify product data sheets.
• Calibration labs – To perform standardized acceptance testing.
• End users in process industries (oil & gas, chemical, power, pharma) – To compare devices from different suppliers on a consistent basis.
• Automation engineers – For factory acceptance testing (FAT) under controlled conditions.

What is IEC 61298-2? (A Quick Refresher)

Before we dive into the "new," we must establish the baseline. The IEC 61298 standard is divided into several parts. Part 2 specifically focuses on Influence tests. These tests determine how a measurement device (like a pressure transmitter or temperature sensor) performs when subjected to external influences that are not the measurand.

Think of it as stress-testing your smart transmitter. The standard defines procedures for: Instrument manufacturers – To verify product data sheets

• Vibration and shock resistance
• Ambient temperature influence
• Humidity and ingress protection (IP)
• Power supply variations
• Electromagnetic compatibility (EMC) - though often referenced to IEC 61326

The "old" version served the industry well for the era of analog 4-20 mA loops. But the industrial world has changed. We now live in the age of IIoT (Industrial Internet of Things), wireless transmitters, and high-speed digital protocols (Ethernet-APL, Profinet). The iec 612982 new update closes the gap between legacy reliability tests and modern digital realities.

2. Establishment of Reference Conditions

The most distinct feature of this standard is the rigorous definition of the testing environment. To isolate the device's performance from external interference, the standard sets strict parameters for:

• Ambient Temperature: Typically defined (e.g., 20°C to 25°C) to prevent thermal expansion or drift during testing.
• Relative Humidity: Kept within a specific range (e.g., 45% to 75%) to prevent condensation or electrostatic effects.
• Power Supply: The voltage and frequency must be regulated within tight tolerances.
• Vibration and Shock: The device must be isolated from mechanical vibrations unless the test specifically requires them.
