IUPAC Silver book—corrigendum

From the journal Chemistry International

In April 2017, Chemistry International announced the release of the second edition of the so-called IUPAC Silver book, i.e. the “Compendium of Terminology and Nomenclature of Properties in Clinical Laboratory Sciences” [1]. The authors of the Silver Book have since shared a change to Section 6.10.5. The description of how the combined standard measurement uncertainty is obtained has been rephrased in order to conform with the International vocabulary of metrology (JCGM 200:2012 International vocabulary of metrology—basic and general concepts and associated terms (VIM), BIPM, Sèvres.

Section 6.10.5 now reads:

Each component of measurement uncertainty estimated by Type A or B evaluation can be characterized by a variance, u2, that may be calculated from the distribution of values with repeated measurements (Type A) or assessed by using available knowledge (Type B). The positive square root of such a variance is called standard measurement uncertainty, . Standard measurement uncertainty values may be combined by the law of propagation of uncertainty [JCGM 100: 2008, section 5]: the result is called the combined standard measurement uncertainty, uc [ref. 20, concept 2.31]. Such a quantity has the same dimension as the quantity being measured and is expressed in the same unit.
