1. Scope*

1.1 These test methods cover the determination of nitrite
nitrogen, nitrate nitrogen, and combined nitrite-nitrate nitrogen
in water and wastewater in the range from 0.05 to 1.0 mg/L
nitrogen. Two test methods2 are given as follows:
Test Method A—Automated Cadmium Reduction 9 to 16
Test Method B—Manual Cadmium Reduction 17 to 24

1.2 These test methods are applicable to surface, saline,
waste, and ground waters. It is the user’s responsibility to
