Calibration gases definition

Calibration gases means gases of precisely known concentrations that are used as references for establishing or verifying the response curve of a measurement device.
Calibration gases or “Span Gases” shall means gases of accurately known concentration that are used as references for establishing or verifying the calibration curve and accuracy of an engine exhaust gas analyzer which are approved by the Department.
