This is arguably the most valuable part for field engineers. Influence quantities are external factors that change the instrument's output. Part 3 provides methods to test for:

The standard defines the method for determining the performance of the device: iec 612982

To ensure compliance with IEC 61298, manufacturers must design and test their devices according to the standard's requirements. Certification bodies, such as the International Electrotechnical Commission (IEC) and the German Institute for Accreditation (DAkkS), offer certification programs for devices that meet the standard's requirements.
