Refer to this document for terminology and explanations of statistical concepts. 9.2 The precision details in this precision statement give an estimate of the precision of this test method with the materials u… <\/td>\n<\/tr>\n | ||||||
| 6<\/td>\n | 9.3 The precision results are given in Table 1. The precision is expressed on the basis of a 95 % confidence level for the values established for repeatability r and reproducibility R. 9.4 The results contained in Table 1 are mean values and give an estimate of the precision of this test method as determined in … 9.5 A type 1 precision was determined, based on the sampling method used for the latex samples in the ITP. 9.6 Repeatability: The repeatability r (in measurement units) of this test method has been established as the appropriate value … 9.7 Reproducibility: The reproducibility R (in measurement units) of this test method has been established as the appropriate va… 9.8 Bias: In test method terminology, bias is the difference between an average test value and the reference (or true) test property value. Table 1 – Estimate of precision of determination of sludge content r = 2,83 \u00d7 sr where r is the repeatability (in measurement units) and sr is the within-laboratory standard deviation. R = 2,83 \u00d7 sR where R is the reproducibility (in measurement units) and sR is the between-laboratory standard deviation. 10 ” Test report a) a reference to this International Standard; b) all details necessary for identification of the test sample; c) the results, and the units in which they have been expressed; d) any unusual features noted during the determination; e) any operation not included in this International Standard or in the International Standard to which reference is made, as well as any operation regarded as optional. <\/td>\n<\/tr>\n | ||||||
