ASTM C670
Full Name
ASTM C670 – Standard Practice for Preparing Precision and Bias Statements for Test Methods for Construction Materials
Scope
The form and style for ASTM Standards requires that all test methods contain statements on precision and bias. Further, the precision statement is required to contain a statement on single-operator precision (repeatability) and a statement on multilaboratory precision (reproducibility).
This practice provides guidance for preparing precision and bias statements that comply with these requirements.
