When gauges are tested, they must read within what percent of a calibrated gauge?

Gauge accuracy is checked against a calibrated standard, and readings must fall within three percent of that reference. This three percent window keeps measurements reliable for safety checks while avoiding overly stringent demands. A tighter tolerance, such as one percent, would be stricter than needed; a five percent tolerance would be too loose for dependable readings.
