Jan 27, 2017A common standard to pass a bump test is the instrument must detect 50% of the calibration gas concentration exposed to the instrument. In these examples, the instrument would be required to detect 50ppm of CO and 17.5ppm of H 2 S. Only after 34 months of gradual sensor drift would the instruments would fail a bump test.
