The standard ensures that performance data for industrial instrumentation—such as sensors, actuators, and controllers—is reliable, repeatable, and comparable across different manufacturers. It applies to both analogue and digital devices
: System testing laboratories and production facilities rely on the ANSI Webstore listed IEC 61298-2 guidelines to issue official conformity certificates.
Defines industry vocabulary like "transfer function," "non-linearity," and "repeatability".
For professionals in instrumentation, quality control, or process engineering, understanding and applying the principles of IEC 61298-2 is crucial for maintaining operational excellence and safety in industrial processes. iec 612982
The standard is for manufacturers, calibration labs, and end-users to compare devices from different suppliers under repeatable conditions.
Before testing begins, the device must be installed according to the manufacturer's instructions. A "warm-up" period is required to ensure the device reaches thermal equilibrium and electronic stability.
The correct standard is not a single document but a multi-part series that provides the foundation for how process measurement and control devices are tested and evaluated globally. This article clarifies the correct designation, explores the content and structure of the IEC 61298 series, and discusses its pivotal role in industries ranging from manufacturing to smart infrastructure. The standard ensures that performance data for industrial
: Modern smart sensors, fieldbus transmitters, and edge-computing microcontrollers.
IEC 61298-2 is an international standard developed by the International Electrotechnical Commission (IEC). It specifies the general methods and procedures for testing the performance of process measurement and control devices (such as transmitters, controllers, recorders, and converters).
: Classic 4–20 mA transmitters, legacy pneumatic devices, and simple signal conditioners. A "warm-up" period is required to ensure the
Electromagnetic interference (EMI), radio frequency interference (RFI), and mechanical vibration must be shielded or filtered out. Crucial Testing Procedures
The global standard outlines the rigorous procedures required to evaluate the performance of industrial process measurement and control devices under standardized reference conditions . Maintained by the International Electrotechnical Commission (IEC) , specifically Subcommittee 65B (Devices and process analysis), this framework ensures that hardware from different manufacturers can be compared objectively using repeatable benchmark testing. Whether dealing with analogue or digital instruments, adhering to this standard allows automation engineers to quantify baseline accuracy, structural reliability, and long-term signal drift. 1. Scope and Core Objectives
As industrial IoT (IIoT) and "smart" sensors proliferate, IEC 61298 is being extended. The upcoming amendments will address:
Beyond basic performance, electrical and structural integrity are meticulously mapped: Evaluated Characteristic Test Objective
Its strength lies in systematic influence testing and rigorous uncertainty control . However, it is obsolete in parts (EMC references, missing reliability) and incomplete for digital, wireless, or safety-related devices.
