22、ared by Technical Committee CEN/TC 125 “Masonry”, the secretariat of which is held 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 September 2016, and conflicting national standards shall
23、be withdrawn at the latest by September 2016.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 responsible for identifying any or all such patent rights. This document supersedes EN 13914-1:2005
24、. The first draft of this document was prepared by the European Union of Contractors of Plastering, Dry Lining, Stucco and Related Activities (UEEP) at the request of the CEN Technical Sector Board (Resolution No. BTS1/56/1991). This document gives requirements and recommendations for building detai
25、ls, design and materials considerations, the selection of mixes and the application of renders based on cement, lime or organic binders for use on external backgrounds. NOTE The term rendering mortar is used in the European Standard product specification EN 998-1, but to reflect common usage in rela
26、tion to this document and for ease of reference the term render (noun) has been used. A rendered finish may be applied to a variety of backgrounds, either to improve resistance to rain penetration and weathering and/or for aesthetic reasons. For the purposes of this document (except where stated in
27、relation to a specific product standard) the term strength should be considered in terms of relative strengths between different types of backgrounds compared with the nominal strengths of prescribed render mixes. Although it may be possible to consider this in terms of compressive strength, this st
28、andard deals with aspects of a craft as opposed to design calculations. Therefore strength is not considered in terms of numerical values derived from testing. Similar considerations also apply to terms such as movement, absorbency and permeability etc. used in this document. This document refers on
29、ly to the technical suitability of materials and/or procedures. During the application the user will need to observe any legal obligations relating to health and safety at any stage. Because this document is a code-like document as opposed to the more conventional European product standard, it is ap
30、propriate to mention that, as with product standards, the use of the verbal form shall denotes a requirement for which verification of compliance has to be able to be demonstrated. Recommendations are denoted by the verbal form should and should be followed unless there is a justifiable reason for n
31、ot doing so. It is not the function of this standard to assign responsibility for the design and application of any work or actions mentioned within to any specific party. Such responsibility is a matter for other documentation associated with the work, e.g. the contract. DIN EN 13914-1:2016-09EN 13
32、914-1:2016 (E) 5 It has been assumed in the drafting of this document that the application of its provisions is entrusted to appropriately qualified and experienced people, for whose guidance it has been prepared. According to the CEN/CENELEC Internal Regulations, the national standards organization
33、s 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,
34、Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 13914-1:2016-09EN 13914-1:2016 (E) 6 1 Scope This European Standard specifies requirements and recommendations for the design, preparation and application of renders
35、based on cement, lime or other mineral binders, and/or combinations thereof, masonry cement and polymer modified binder based external renderings, in accordance with EN 998-1 or site made renders; renders based on organic binders in accordance with EN 15824 on all common types of backgrounds. It inc
36、ludes rendering on both new and old backgrounds and the maintenance and repair of existing work. This document gives guidance on the use of established site, factory and semi-finished factory made renders. This document does not cover the following: a) the use and application of special renders for
37、liquid retaining structures, e.g. coatings, and for backgrounds to cladding systems; b) the structural repair of concrete; c) the installation of external thermal insulation composite systems (ETICS); d) the specification and use of sealants used to seal joints for use with rendering; e) the use of
38、gypsum based renders used externally, but their use may be permitted in some countries; Gypsum based products soften when subject to prolonged moist conditions. The use of such products externally will depend upon the climatic conditions where the render will be used and on the local building tradit
39、ions. With the exception of some drier countries in southern Europe gypsum based renders are generally not recommended for external use and are therefore not included within the scope of this document. However, their use may be permitted and controlled locally.1)f) renders on historical monuments or
40、 buildings in protected areas which may be regulated by national codes; g) the design and installation of flashings at windowsills and elsewhere. Because of the many and varied materials and practices and different climatic conditions in Europe it is not possible for certain aspects of the standard
41、to enter into sufficient detail to be fully usable to practitioners in each country. Appropriate guidance to complement, but not alter any basic European recommendations is given in documentation prepared by each country. Aspects of this European Standard whose basic recommendations may need to be c
42、omplemented are indicated where they occur by a footnote referencing this clause. 1) Refer to final paragraph of Clause 1 for further information.
