This document specifies the characteristics and the methods of test for pigments for use in the colouring of building materials based on cement and cement/lime combinations. Pigments covered by this document may also be used in pure lime mortar. For this application@ see EN 459-1 and EN 459-2. Pigments for this purpose may be single pigments@ blends of pigments@ or blends of pigments and extenders@ in powder or granular form@ or aqueous preparations. Pigments typically belong to one of the following classes of compounds: ?? synthetic or natural oxides and hydroxides of iron; ?? oxides of chromium@ titanium and manganese; ?? complex inorganic pigments@ for example combinations of the above mentioned metal oxides and hydroxides with cobalt@ aluminium@ nickel and antimony oxides and hydroxides; ?? ultramarine pigments; ?? phthalocyanine blue and green; ?? elemental carbon (shall be regarded as an inorganic pigment); ?? blends of the above materials (which may also include extenders).
