17、eld by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2011, and conflicting national standards shall be withdrawn at the latest by March 2011. Attention is drawn to the possibility tha

18、t some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This European Standard supersedes EN 998-1:2003. The main technical changes compared to the previous edition are in relation to

19、 thermal conductivity, where the basis for the declared value has been specified, and in relation to evaluation of conformity, where more details have been given. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and suppo

20、rts the essential requirements of the EU Construction Products Directive (89/106/EEC). For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this document. EN 998 Specification for mortar for masonry consists of: Part 1: Rendering and plastering mortar. Part 2:

21、 Masonry mortar. According 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, France, Germany, Greece, Hungary,

Special properties can be achieved by the type of aggrega

24、tes, admixtures and/or additions used. Rendering/plastering mortars are defined a) according to the concept as either: designed mortars; or prescribed mortars. b) according to the mode of manufacture as either: factory-made mortars; semi-finished factory mortars; or site-made mortars. c) according t

25、o the properties and/or use, as either: general purpose rendering/plastering mortar; lightweight rendering/plastering mortar; coloured rendering mortar; one-coat rendering mortar; renovation rendering/plastering mortar; thermal rendering/plastering insulating mortar. Rendering/plastering mortars do

26、not attain their final characteristics until properly hardened after application. The functions performed by a rendering/plastering mortar depend on the properties of the type of materials used, on the thickness of the coats and the type of application. In addition, rendering/plastering mortars dete

27、rmine the surface of the construction. Regional differences in construction practices and climate, and different constituents for rendering/plastering mortars do not allow for the establishment of standard mix proportions for prescribed mortar that would be applicable in all of Europe. Therefore, th

28、e specification of such mix proportions (recipes) and fields of application should be based on practice and experience available in the place of use.

29、icense from IHS-,-,-BS EN 998-1:2010EN 998-1:2010 (E) 5 1 Scope This European Standard is applicable to factory made rendering/plastering mortar based on inorganic binders for external (rendering) and internal (plastering) use on walls, ceilings, columns and partitions. It contains definitions and f

30、inal performance requirements. It does not cover mortars where calcium sulphate binder is the principle active binding agent. Calcium sulphate binder can be used as an additional binder together with air lime. If air lime is the principle active binding component, the rendering/plastering mortar is

31、covered by this European Standard. If the calcium sulphate binder is the principle active binding component, the mortar is covered by EN 13279. The classification is carried out by the producer of the mortar. Special fire resistant- and acoustical mortars, mortars for structural repair and surface t

32、reatments of building elements such as materials for smoothing or trueing, paints, coatings, thin-layer organic renders/plasters and prefabricated units (e.g. plaster boards) are not dealt with in this European Standard. This European Standard covers rendering/plastering mortars defined in Clause 3

33、with the exception of site made rendering/plastering mortars. However, this European Standard or part of this European Standard may be used in conjunction with codes of application and national specifications covering site made mortars. 2 Normative references The following referenced documents are i
