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


Changes to the Appendix are meant to improve clarity. The correct wording of “identical test specimens” as stated in the definitions in 3.2.4 and 3.2.5 has been added in all the examples where it is applicable. In footnote A of X1.4.1 Example 5, the language has been changed to match that of other similar examples in this appendix. Also, example 8 has been moved to be between Table X1.1 and X1.2. Other editorial changes were made.
