    Rationale

    Section 12 Calibration and Standardization has a mathematical error in calculating the calibration standards. The Stock Solution (Sec 8.21) is appox 100ug/mL. The diluted calibration standards per the method should be approximately 1, 15 and 30 ug/mL and not mg/mL as written in the method. The revision to D5808 is to correct this error/oversight. 12. Calibration and Standardization 12.1 Using the chloride standard stock solution (see 8.21), make a series of three calibration standards covering the range of expected chloride concentration. 12.2 Into three 100-mL volumetric flasks, respectively pipet 1, 15, and 30 mL of chloride stock solution and dilute to the mark with solvent. (The standards are approximately 1 mg Cl/mL, 15 mg Cl/mL and 30 mg Cl/mL
