A common misconception: "If my new transmitter is 0.04% accurate, it will stay that way for 5 years." Part 4 testing often reveals that thermal cycling, diaphragm fatigue, or electronic component aging cause gradual decay. Responsible manufacturers use IEC 61298-4 to publish realistic drift specs.

The standard defines how to conduct tests to verify claims made in product data sheets, ensuring a "level playing field" for comparing devices from different manufacturers. iec 612982
