While Part 2 focuses on steady-state accuracy, it also introduces dynamic performance testing:
For absolute pressure transmitters and barometric sensors, the edition adds:
The series is divided into four parts:
Understanding the "New" IEC 61298-2: Key Updates in Performance Testing for Process Devices
The algebraic difference between the device's output value and the conventional true value. iec 612982 new
: Testing insulation resistance, power consumption, and dielectric strength. Drift Measurement
Covers how environmental and operational factors—such as temperature, vibration, and electromagnetic interference—impact device reliability.
Despite the scope changes, the core methodologies for establishing a device's baseline metrics remain rigorous. The tests specified under reference conditions address four primary performance areas: Accuracy-Related Factors
🔹 – Proposals for adding digital communication tests (IO-Link, OPC UA) to future revisions. 🔹 Improved environmental testing – More realistic temperature + vibration combined cycles. 🔹 Cybersecurity considerations – Not yet in IEC 61298-1 to -4, but likely in a new part. While Part 2 focuses on steady-state accuracy, it
The latest version ensures alignment with modern digital and smart transmitters (HART, Fieldbus, Profibus, IO-Link). While the 2008 edition already covers analog and digital outputs, any newer confirmation or amendment clarifies:
A core concept of Part 2 is the . These are the ideal environmental and supply conditions under which the device is meant to operate optimally. Typical reference conditions defined include:
: For specialized hardware, this standard is designed to be used alongside product-specific standards that detail additional, unique tests. Standardization
IEC 61298-2:2019 represents a significant step forward in standardizing inputs and outputs for process automation. The new developments in the standard are poised to support the evolving needs of the industry, facilitating more efficient, flexible, and secure process automation systems. As the industry continues to adopt digital transformation and Industry 4.0 technologies, the guidelines provided by IEC 61298-2:2019 will play a crucial role in ensuring effective and interoperable solutions. Despite the scope changes, the core methodologies for
Process measurement and control devices - General methods and procedures for evaluating performance - Part 2: Tests under reference conditions
Defines methods for frequency response and step-response testing to ensure control system stability.
The specific (e.g., water management, chemical process automation) you operate within.
Since this is the most frequently failed test under the standard, let's examine a practical example.
