Pigments for the colouring of building materials based on cement and/or lime - Specifications and methods of test

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).

Pigmente zum Einfärben von zement- und/oder kalkgebundenen Baustoffen - Anforderungen und Prüfverfahren

Dieses Dokument legt die Merkmale und Prüfverfahren für Pigmente fest, die zum Einfärben von Baustoffen aus Zement und Zement-/Kalkmischungen verwendet werden.
Pigmente nach diesem Dokument dürfen auch in reinem Kalkmörtel verwendet werden. Für diese Anwendung siehe EN 459-1 und EN 459-2.
Pigmente für diese Anwendung dürfen Einzelpigmente, Pigment-Mischungen oder Pigment/Füllstoff-Mischungen in pulveriger oder granulierter Form oder wässrige Präparationen sein.
Pigmente gehören üblicherweise zu einer der folgenden Klassen von Stoffen:
-   synthetische oder natürliche Oxide und Hydroxide des Eisens;
-   Oxide von Chrom, Titan und Mangan;
-   komplexe anorganische Pigmente, z. B. Kombinationen aus den o. g. Metalloxiden und -hydroxiden mit Cobalt-, Aluminium-, Nickel- und Antimonoxiden und -hydroxiden;
-   Ultramarin-Pigmente;
-   Phthalocyaninblau und -grün;
-   elementarer Kohlenstoff (ist als anorganisches Pigment zu betrachten);
-   Mischungen der o. g. Materialien (die auch Füllstoffe enthalten dürfen).

Pigments de coloration des matériaux de construction à base de ciment et/ou de chaux - Spécifications et méthodes d'essai

La présente Norme européenne spécifie les caractéristiques et les méthodes d'essai qui s'appliquent aux pigments de coloration des matériaux de construction à base de ciment et de combinaisons ciment/chaux.
Les pigments couverts par la présente Norme européenne peuvent également être utilisés dans du mortier de chaux pure. Pour cette application, se reporter à l'EN 459-1 et à l'EN 459-2.
Les pigments destinés à cet usage peuvent être des pigments simples, des mélanges de pigments ou des mélanges de pigments et de matières de charge, sous forme de poudre, de granules ou de préparations aqueuses.
Les pigments appartiennent généralement à l'une des classes de composés suivantes :
-   oxydes et hydroxydes de fer, synthétiques ou naturels ;
-   oxydes de chrome, de titane et de manganèse ;
-   pigments minéraux complexes, par exemple combinaisons des oxydes et hydroxydes métalliques mentionnés ci-dessus avec des    oxydes et hydroxydes de cobalt, d’aluminium, de nickel et d’antimoine ;
-   pigments d'outremer ;
-   bleu et vert phtalocyanine ;
-   carbone élémentaire (doit être considéré comme un pigment minéral) ;
-   mélanges des matières ci-dessus (qui peuvent aussi comprendre des matières de charge).
