General Information
Frequently Asked Questions
CEN/TC 298/WG 2 is a Working Group within the European Committee for Standardization (CEN). It is named "Pigments for building materials based on cement and/or lime" and is responsible for: Standardization of pigments for the colouration of building materials based on cement and lime. This committee has published 4 standards.
CEN/TC 298/WG 2 develops CEN standards. The scope of work includes: Standardization of pigments for the colouration of building materials based on cement and lime. Currently, there are 4 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
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.
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.
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).
