IEC 61298 is a multipart standard for .
4. No diagnostics or prognostics validation
Linearity:
The standard requires a series of "calibration cycles." Typically, this involves increasing the input signal in steps (e.g., 0%, 25%, 50%, 75%, 100%) and then decreasing it back to zero. This reveals: How closely the output follows a straight line. iec 612982
The full standard is available from the IEC Webstore (webstore.iec.ch) or national bodies like ANSI (USA), BSI (UK), or DIN (Germany). Expect to pay a few hundred dollars for the full set. The alarms on Level 4 did not scream; they hissed
Myth 1: "IEC 61298 is only for manufacturers."
False. End users use it for incoming inspection, troubleshooting, and calibration interval justification. Many large oil & gas companies (e.g., Shell, ExxonMobil) reference IEC 61298 in their internal engineering standards. The full standard is available from the IEC
