This European Standard specifies the requirements and the methods of test for pigments for use in the colouring of building materials based on cement and cement\/lime combinations.<\/p>\n
Pigments covered by this European Standard may also be used in pure lime mortar. For this application, see EN 459-1 and EN 459-2.<\/p>\n
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.<\/p>\n
Pigments typically belong to one of the following classes of compounds:<\/p>\n
synthetic or natural oxides and hydroxides of iron;<\/p>\n<\/li>\n
oxides of chromium, titanium and manganese;<\/p>\n<\/li>\n
complex inorganic pigments, for example combinations of the above mentioned metal oxides and hydroxides with cobalt, aluminium, nickel and antimony oxides and hydroxides;<\/p>\n<\/li>\n
ultramarine pigments;<\/p>\n<\/li>\n
phthalocyanine blue and green;<\/p>\n<\/li>\n
elemental carbon (shall be regarded as an inorganic pigment);<\/p>\n<\/li>\n
blends of the above materials (which may also include extenders).<\/p>\n<\/li>\n<\/ul>\n
