010.02 When calibration verification checks are performed by means of approved internal standard(s), all approved evidentiary breath testing instruments shall be able to produce results within +/- 5% of the known target values of the standard(s). This tolerance shall be verified by the normal prescribed program and operation of the testing devices.
010.03 When calibration verification checks are performed with dry gas standards, all approved evidentiary breath testing instruments shall be able to produce results within +/5% of the target value of the dry gas standard after applying applicable altitude or topographic elevation correction factor supplied by the manufacturer.
