Revision of C670-15 Standard Practice for Preparing Precision and Bias Statements for Test Methods for Construction Materials


Changes to Section 7. Bias Statement are meant to improve clarity. In 7.1 the word “of” is added to make the sentence make sense. In 7.3, “here” is removed to improve readability. There is a change to Eq 2 in 7.4.3 to use a lower case “s” to be consistent with Eq 1. In 7.4.4, the word “the” is added to the first sentence and the last sentence is removed because it is redundant to the first sentence.
