21、S EN 12878:2014EN 12878:2014 (E) 4 Foreword This document (EN 12878:2014) has been prepared by Technical Committee CEN/TC 298 “Pigments and extenders”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identi
22、cal text or by endorsement, at the latest by October 2014 and conflicting national standards shall be withdrawn at the latest by January 2016. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held re
23、sponsible for identifying any or all such patent rights. This document supersedes EN 12878:2005. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Construction Production Regulat
24、ion (CPR). For relationship with the Construction Production Regulation, see informative Annex ZA, which is an integral part of this document. EN 12878:2005 has been technically revised as follows: a) requirements for Category B regarding water soluble substances in 4.2.3 modified to accommodate non
25、 powder preparations; b) test method for total chlorine content (5.2.5) changed; c) permission to use alternative test methods with proven correlation to standard methods added; d) light source amended; e) Annex ZA has been changed to consider the new Construction Production Regulation (CPR). Accord
26、ing to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany,
27、Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 12878:2014EN 12878:2014 (E) 5 1 Scope This European Standard specifies the requirements
28、 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
29、 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 ino
30、rganic 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 mater
31、ials (which may also include extenders). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、 and/or lime-based building materials 3.2 single pigment pigment that is of singular (chemical) composition Note 1 to entry: Single pigments contain no substances other than those originating from the pigment manufacturing process. Note 2 to entry: Surface treatment of the primary pigment particles
38、is considered as a part of the pigment manufacturing process. 3.3 pigment blend blend of at least two single pigments, or at least one single pigment and an extender 3.4 aqueous pigment preparation preparation in which a pigment (single pigment or pigment blend) is dispersed in water, with or withou
39、t a dispersion or other agent EXAMPLES of agents are: dispersants; binding agents (resins); solvents; wetting agents; or combinations thereof. 3.5 pigment in granular form preparation in which a pigment (single pigment or pigment blend) is converted into granules, by the use of the binding agent whi
