Revision of D4012-15 Standard Test Method for Adenosine Triphosphate (ATP) Content of Microorganisms in Water


A substantial revision of the Method D4012protcol was approved in 2015. Consequently, a new interlaboratory study (ILS) is needed in order to revise D4012 Section 15 Precision and Bias. This work item includes ILS planning and execution, and revision to D4012 to revise Section 15, based on the ILS Research Reports precision statistics. COVID-19 has postponed the ILS planned for May 2020 and we are anticipating not being able to utilize the lab until 2022 as it is currently restricted to COVID-associated critical research only.
Restrictions are being lifted at the end of March 2022, there will be a need for a slight ramp up period then the ILS will be conducted at the latest in early summer 2022 (May-June) at Dalhousie University
