SIST EN 15824:2017

EN 15824:2017 (E) 4 European foreword This document (EN 15824:2017) has been prepared by Technical Committee CEN/TC 125 “Masonry”, the secretariat of which is held by BSI. This document supersedes EN 15824:2009. 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of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by March 2019.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 European 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 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 annex with indicative frequencies on testing for factory production control (informative); e) revised Annex ZA (informative); f) some minor editorial changes. No changes to existing technical classes and/or threshold levels have been made. According to the CEN-CENELEC Internal Regulations, the national standards organisations 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, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 15824:2017

EN 15824:2017 (E) 5 Introduction The characteristics of external renders and internal plasters based on organic binders are primarily 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 characteristics 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. The 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 of the renders or plasters and the relevant conditions of use. SIST EN 15824:2017

EN 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 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 can 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 assessment 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 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 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
