The standard helps verify that devices perform according to their manufacturer specifications under standardized reference conditions, providing a solid foundation for comparing different instruments. Key Performance Characteristics Evaluated
Evaluates how external factors like temperature, vibration, and humidity affect performance.
It allows engineers to compare different devices from different vendors on an equal footing based on data gathered under the same reference conditions.
The most important change in the new 2026 edition is the from its scope. This type of device will now be covered exclusively by the IEC 62828 series . iec 612982
Based on the standard naming conventions of the International Electrotechnical Commission (IEC), a standard with the exact number 612982 does not exist. The IEC typically uses 5 or 6-digit numerical codes (e.g., 61298, 62061, 61508).
Think of it as the "recipe book" for instrument testing. It ensures that if Company A tests a pressure gauge using IEC 61298-1, Company B in another country will be able to reproduce and trust the results.
The standard enforces identical testing parameters across different global brands. This allows procurement engineers to directly compare the datasheets of competitive instruments. Scope and Device Applicability The standard helps verify that devices perform according
A critical requirement of IEC 61298-2 is the ratio of the accuracy of the test equipment to the device under test (DUT).
Note: A device can be IEC 61298-tested (accurate) but not safe (IEC 61508). Conversely, a safety-certified transmitter can have poor accuracy—but that is usually unacceptable.
The core concept of this standard is the "Reference Condition." These are the specific limits of the operating environment in which the device is tested. While specific reference values can vary based on the device type, standard reference conditions typically include: The most important change in the new 2026
The standard defines several technical metrics used to judge the performance of a device under test (DUT). Key terms and definitions includes:
Beyond basic performance, electrical and structural integrity are meticulously mapped: Evaluated Characteristic Test Objective
Manufacturers rely on these tests as a baseline for internal research, development, and end-of-line production verification.
