26、 and Bias10.1 Precision The test results for representation of per-formance of the material will depend on the variability of thematerial, plus sampling and specimen preparation.10.1.1 The results were evaluated using Practice E691.Repeatability and reproducibility are herein defined as 2.8times the
27、 corresponding standard deviation to obtain a 95%confidence level. Repeatability is the variability between testresults within each laboratory, and reproducibility is thevariability between test results from different laboratories.10.1.2 Interlaboratory tests The results of interlaboratorytests cond
