| homogeneity | |||
| Uniform structure or composition of a material with respect to one or more specified properties. | |||
| Note 1: | A material is said to be homogeneous with respect to a specified quantity if the quantity values measured using specified aliquots of the material aliquots of a specified size do not fall outside a specified interval. See minimum sample size. | ||
| Note 2: | In the homogeneity study of a candidate reference material, it is distinguished whether the analytical samples are taken from different supply units or from a single supply unit (termed “between-bottles homogeneity” or “within-bottle homogeneity”, respectively). | ||
| Note 3: | Inhomogeneity is a source of measurement uncertainty. | ||
| Note 4: | Detailed guidance for the assessment of homogeneity of reference materials, is given in ISO Guide 35.24 | ||
