ASTM WK76460
This new standard guide is needed because many laboratories have veered away from the two EPA methods because they are only relevant for drinking water. All other samples must be analyzed by modifications of these prescriptive methods and the lab-specific SOP comes with its own acceptance criteria. This guide gives data validators a tool for reviewing results developed by these non-standard methods.
