To achieve complete compliance, verify your testing environment conforms to the precise temperature and power thresholds detailed in the Official IEC Webstore Publication. Share public link
IEC 61298-2 is the foundational standard for verifying process control instrumentation performance. By isolating the device from environmental variables, it reveals the true engineering capabilities of the hardware. For manufacturers, it is a requirement for product certification; for end-users, it is a guarantee of reliability and a tool for accurate system design.
: Instrument developers use the standard to design and rigorously verify their new products. The standard dictates the tests required to validate claims of accuracy, repeatability, and environmental robustness before a product is released to the market. It serves as a benchmark for internal quality control.
The IEC 61298 standard is essential for several reasons: iec 612982
: Simplifies compliance testing, speeds up time-to-market, and offers globally recognized engineering proofs.
In the real world, instruments are rarely subjected to perfect reference conditions. This section quantifies how a device's performance is affected by external environmental and operating factors.
Accuracy evaluation forms the baseline of the testing protocol. It tracks how closely a device tracks its intended physical ideal. For manufacturers, it is a requirement for product
Does the device give a different reading if the pressure is rising versus falling?
This test assesses the device's ability to provide the same output for the same input, multiple times consecutively, under identical conditions. High repeatability is crucial for reliable control systems. 5. Start-up Drift and Long-term Drift
Together, these four parts create a complete methodology, from the initial planning of tests under ideal conditions to the systematic reporting of final results. It serves as a benchmark for internal quality control
The standard details how to pick span ranges and dictates the minimum number and sequence of evaluation points across upscale and downscale paths.
The property where a device provides different output values for the same input, depending on whether the input value was reached by increasing or decreasing.
Implementing IEC 61298-2 offers immediate advantages across the entire automation supply chain:
