EXAMPLE sex of a human being, colour of a paint sample, ISO two-letter country code, sequence of amino acids in a polypeptide.

Note 1 to entry: While the colour of a paint sample is sometimes considered to be a nominal property, it is also recognized that a pure colour can be characterized by the wavelength of electromagnetic radiation, which is a quantity that can be measured.

Note 2 to entry: A nominal property has a value, which can be expressed in words, by alpha-numerical codes, or by other means. This value is not to be confused with the nominal value of a quantity (see IEV 151-16-09).

Note 3 to entry: Nominal properties are distinguished from quantities, which are properties that have a magnitude, i.e. they can be compared in terms of greater or lesser.
