New Precision and Bias statements were added to C1718-14 based on a recent interlaboratory study that was conducted to generate single-operator repeatability and multi-operator reproducibility statements. This work was conducted at Middle Tennessee State University and was analyzed under ASTM ILS # 1012. The development of the new Precision and Bias statements was detailed in an ASTM symposium paper that was presented in June 2014 at the meeting in Toronto. Currently, C1718-14 references the ILS study (Research Report RR-C15-1000). This ballot proposes to add a reference to the symposium paper to provide more background information to users of the standard.
