1.1 ,These test methods cover the atomic absorption determination of dissolved and total recoverable manganese in water and certain wastewaters. Section 34 on Quality Control pertains to these test methods. Three test methods are given as follows:
| Test Method | Concentration Range | Sections |
| A—,Atomic Absorption, | 0.1 to 5 mg/L | 7 to 15 |
| B—,Atomic Absorption, | 10 to 500 μ,g/L | 16 to 24 |
| C—,Atomic Absorption, | 5 to 50 μ,g/L | 25 to 33 |
