22、 shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by March 2019. This document has been prepared under a mandate given to CEN by the Euro

23、pean Commission and the European Free Trade Association, and supports basic requirements for construction works of the EU Construction Products Regulation (Regulation (EU) No 305/2011. For relationship with EC Regulation, see informative Annex ZA, which is an integral part of this document. The most

24、 significant changes compared to the previous edition include: a) implementation of new regulatory (CPR) terminology where relevant; b) revised text in 4.6 Thermal conductivity (deriving from EN 998-2); c) revised clauses on Assessment and verification of constancy of performance (AVCP); d) new anne

BS EN 15824:2017EN 15824:2017 (E) 5 Introduction The characteristics of external renders and internal plasters based on organic binders are pri

28、marily determined by the type or types of binders used and their respective proportions. Organic renders and plasters can be defined according to: the chemical and physical nature of the main active binder(s) and its state of dissolution, dispersion, or powder, which is decisive for the final charac

29、teristics of the surface covering with one or several coats; the finishes determined by the aggregate distribution and application technique; the characteristics and/or type of use. Renders and plasters do not attain their final characteristics until properly dried and hardened after application. Th

30、e functions performed by renders and plasters depend on the characteristics of the type of raw materials used, on the thickness of the coats and the type of application. The manufacturer designates the appropriate characteristics for end use and appearance and should give information about the use o

31、f the renders or plasters and the relevant conditions of use. BS EN 15824:2017EN 15824:2017 (E) 6 1 Scope This European Standard is applicable to factory-made renders and plasters based on organic binders used for external or internal covering on walls, columns, partitions and ceilings. The products

32、 are manufactured in paste form, ready to use, or in powder form. This European Standard is also applicable to renders and plasters with inorganic binders such as silicates, silanes, siloxanes and silicones. Renders and plasters can form the final surface of the structure, textured or not, or they c

33、an provide a levelling of the substrate, adequately smooth for subsequent decorative treatments. This European Standard contains definitions and final performance requirements. It includes relevant characteristic categories to designate renders and plasters. This European Standard provides for the a

34、ssessment and verification of constancy of performance (AVCP) of the product to this European Standard. The marking requirement for products covered by this European Standard is included. This European Standard is not applicable to coating materials and coating systems according to EN 1062-1 and EN

35、13300. This European Standard does not contain recommendations for the design and application of renders and plasters. However, this European Standard may be used for definition of renders and plasters in conjunction with codes of application and national specifications for execution of works. 2 Nor

42、internal plastering Note 1 to entry: Render or plaster may be the product delivered by the manufacturer or the applied material on site. 3.2 declared value value that a manufacturer is confident in achieving, taking into account the precision of test method, the variability of the production process

43、(es) and the product performance 3.3 substrate surface to which the plaster or render is applied or is to be applied Note 1 to entry: Examples are coated or uncoated masonry, concrete, gypsum elements, gypsum or cementitious boards for walls, columns, partitions and ceilings. 3.4 product-type set of

44、 representative performance levels or classes of a construction product, in relation to its essential characteristics, produced using a given combination of raw materials or other elements in a specific production process Note 1 to entry: The definition is taken from Regulation (EU) No. 305/2011 4 P

45、roduct characteristics 4.1 General The requirements on characteristics for dried and hardened renders and plasters shall be defined using the test methods and procedures referred to in this European Standard. For these tests, renders and plasters in paste form shall be sampled in accordance with EN

46、ISO 15528 and renders and plasters in powder form in accordance with EN 1015-2. NOTE The characteristics of renders and plasters are specified under laboratory conditions and cannot always be directly compared with the characteristics obtained under site conditions. In all tests the layer thickness
