Gauges must be replaced or tested by comparison with a calibrated gauge every how many years?

Explanation:
Gauges can drift and lose accuracy over time, so they’re checked against a calibrated reference at regular intervals to ensure readings stay reliable. The five-year interval is the standard practice: compare the gauge to a calibrated standard, and if it reads within the allowed tolerance, it can stay in service until the next check; if it doesn’t, replace or recalibrate it. This timing balances practical maintenance with the risk of inaccurate readings, though always follow manufacturer guidelines or local codes, as some situations may call for different intervals.
