D4012 - Standard Test Method for Adenosine Triphosphate (ATP) Content of Microorganisms in Water

The precision of this test method is based on an interlaboratory study of ASTM D4012, Test Method for Adenosine Triphosphate (ATP) Content of Microorganisms in Water, conducted in 2022. Eight volunteer laboratories were asked to test 18 different materials. Every “test result” represents an individual determination, and all participants were instructed to report two replicate test results for each material. Practice E691 was followed for the design of study and analysis of the data.
