ASTM D3608: Standard Test Method for Nitrogen Oxides (Combined) Content in the Atmosphere by the Griess-Saltzman Reaction
DOD Adopted ANSI Approved Approved
This test method covers the manual determination of the combined nitrogen dioxide (NO2) and nitric oxide (NO) content, total NOx ; in the atmosphere in the range from 4 to 10 000 µg/m³ (0.002 to 5 ppm (v)).
The maximum sampling period is 60 min at a flow rate of 0.4 L/min.
The values stated in SI units are to be regarded as standard. The values given in brackets are for information only.
