Title: IEC 61298-2:2022 - New Standard for Process Automation and Control

Introduction:

The International Electrotechnical Commission (IEC) has recently published a new standard, IEC 61298-2:2022, which provides guidelines for process automation and control. This standard is part of the IEC 61298 series, which focuses on process automation and control devices.

What is IEC 61298-2:2022?

IEC 61298-2:2022 is a standard that specifies requirements for the design, testing, and documentation of process automation and control devices, including sensors, actuators, and controllers. The standard covers various aspects, such as:

1. Device requirements: The standard defines requirements for device performance, accuracy, and reliability.
2. Testing and validation: It outlines procedures for testing and validating device performance, including environmental testing and electromagnetic compatibility (EMC) testing.
3. Documentation: The standard specifies requirements for device documentation, including user manuals, technical documentation, and labeling.

Key Changes and Updates:

The new IEC 61298-2:2022 standard introduces several key changes and updates, including:

1. Improved device performance requirements: The standard includes updated requirements for device performance, such as accuracy, response time, and stability.
2. Enhanced testing and validation procedures: The standard provides more detailed testing and validation procedures to ensure device reliability and performance.
3. Increased focus on cybersecurity: The standard includes requirements for device cybersecurity, such as secure communication protocols and data protection.
4. Alignment with other IEC standards: The standard is aligned with other IEC standards, such as IEC 61508 and IEC 62443, to ensure consistency and interoperability.

Impact on Industries:

The IEC 61298-2:2022 standard will have a significant impact on various industries that rely on process automation and control, including:

1. Process industries: Chemical, oil and gas, pharmaceutical, and food processing industries will benefit from improved device performance, reliability, and cybersecurity.
2. Manufacturing: Discrete manufacturing, such as automotive and aerospace, will benefit from standardized device requirements and testing procedures.
3. Energy and utilities: Power generation, transmission, and distribution industries will benefit from improved device performance and cybersecurity.

Conclusion:

The new IEC 61298-2:2022 standard provides a comprehensive framework for process automation and control devices, ensuring improved performance, reliability, and cybersecurity. Industries that adopt this standard will benefit from increased efficiency, reduced costs, and enhanced safety. As a result, manufacturers, users, and regulators should be aware of the changes and updates introduced in this standard.

• Challenge: Cleaning-in-place (CIP) and sterilization-in-place (SIP) cause rapid temperature/humidity swings.
• New standard benefit: Rapid thermal cycling (10°C/min) tests reveal drift in temperature sensors after autoclaving.
• Action: Calibration labs must revise their uncertainty budgets to include the new influence quantities.

4. Extreme Humidity Cycling (Condensation Active)

Previous humidity tests were steady-state (e.g., 95% RH at 40°C). The iec 612982 new introduces "condensation cycling."

• The procedure: Ramp from 25°C/80% RH to 55°C/95% RH, hold for 6 hours, then crash cool to 10°C in 15 minutes, forcing condensation inside the electronics housing.
• The check: The device must maintain specified accuracy during the condensation event and recover fully within 5 minutes of the return to ambient.
• Industry shock: Low-cost Chinese transmitters that lack hydrophobic coatings on PCBs are being completely washed out of the market by this single test.

Immediate Actions (0–3 months)

• Gap analysis: Compare your existing type-test report against the new requirements.
• Identify critical changes: For most devices, humidity cycling and digital integrity tests are the biggest hurdles.
• Update quality documentation: Revise your internal test procedures to reference IEC 61298-2:202X.

The Technical Deep Dive: Random Vibration vs. Sinusoidal

To truly impress your reliability team, you need to understand the physics behind the iec 612982 new vibration clause. The newest version of IEC 61298-2 , titled

• 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.

The new standard defines three severity classes:

• Class 1 (General): 0.01 g²/Hz (Light industrial)
• Class 2 (Routine): 0.02 g²/Hz (Standard pumps)
• Class 3 (Severe): 0.05 g²/Hz (Compressors, heavy crushers)

Note: Class 3 is new. It did not exist in the 2010 version.
