C.

for COMS, the beginning of the out of control period is the time corresponding to the completion of a calibration error audit in which the calibration error exceeds three percent of the average audit value. The end of the out of control period is the time corresponding to the completion of the next calibration error audit in which the calibration error is three percent or less of the average audit value.

Subp. 12.

Recertification test.

"Recertification test" means conducting a certification test on a CEMS or COMS which has been previously certified. Recertification tests shall be conducted according to the same procedures and are subject to the same requirements as certification tests, except as noted in parts 7017.1004 to 7017.1220.
