If two consecutive Type A Tests fail to meet either.75 La (259,500 SCCM) or.75 Lt (46,200 SCCM), a Type A test shall be performed at least every 18 months until two consecutive Type A tests meet either.75 La (259,500 SCCM) or.75 Lt (46,200 SCCM) at which time the above test schedule may be resumed.

1.
Confirms the accuracy of the Type A test by verifying that the difference between supplemental and Type A test data is within 0.25 La (86,500 SCCM) or 0.25 Lt (15,400 SCCM).
