Iec 612982 [exclusive] Online

IEC 61298 is a critical international standard for Process measurement and control devices. It is published in multiple parts and covers general methods and procedures for evaluating the performance of industrial-process measurement and control devices (such as transmitters, sensors, and controllers).

Process Measurement and Control Devices – General Methods of Testing Performance – Part 2: Tests under Reference Conditions

Structure of IEC 61298 (Current edition: 2008–2014)

| Part | Title | Key Focus | |------|-------|------------| | 1 | General procedures | Definitions, reference conditions, test uncertainty, test report structure | | 2 | Reference conditions and tests for static performance | Accuracy, hysteresis, repeatability, dead band, resolution, static error | | 3 | Tests for influence quantities | Temperature, humidity, static pressure, vibration, shock, mounting position, supply voltage/frequency, RFI (radiated/conducted), common mode interference | | 4 | Dynamic response tests | Step response, ramp response, frequency response (Bode plots), time constant, settling time | | 5 | Reliability testing (withdrawn? Merged into IEC 61508/61511) | Not actively maintained; reliability is now covered by functional safety standards |

IEC 61298 provides several key features and benefits, including:
