This European Standard shall be

17、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of an identical text or by endorsement, at the latest by September 2016, and conflicting national standards shall be withdrawn at the latest by September 2016. Attention is drawn to the possibility that some of the elements of this docum

18、ent 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 13914-2:2005. The initial draft of this document was prepared by the European section of International Union of Contractors of Plasteri

19、ng, Dry Lining, Stucco and Related Activities (UIEP) at the request of the CEN Technical Sector Board (Resolution No.BTS1/56/1991). It has been revised by CEN/TC 125/WG 5 in conjunction with experts of CEN/TC 241. Relevant data are summarized in a series of tables. This part of EN 13914 applies to t

20、he design of plaster made of mortars containing inorganic and organic binders and mineral aggregate1)which is applied to internal vertical and soffit surfaces of structures. As this standard is a code-like document as opposed to the more conventional European product standard, it is appropriate to m

21、ention 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 not doing so. I

22、t is not the function of this standard to assign responsibility for the design and application of any work or actions mentioned herein to any specific party. Such responsibility is a matter for other documentation associated with the work, e.g. the contract. It has been assumed in the drafting of th

23、is document that the application of its provisions is entrusted to appropriately qualified and experienced persons, for whose guidance it has been prepared. The content of CEN Technical Reports containing guidance relating to the design, preparation and application of plaster and plastering systems

24、for gypsum (CEN/TR 15124), cement and/or lime (CEN/TR 15125) and polymer plasters (CEN/TR 15123) has been included. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulg

25、aria, 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, Slovakia, Slovenia, Spain, Sweden, Switzerland, Tu

BS EN 13914-2:2016EN 13914-2:2016 (E) 4 1 Scope This European Standard deals with the design considerations and essential principles for internal plastering systems and applicatio

27、n of plastering systems. The different parts of the EN 13914 series of standards specify requirements and recommendations for detailing, design and material considerations, the selection of mixes and the application of gypsum plasters, gypsum/lime plasters, lightweight plasters, lime/gypsum-, cement

28、- and cement/lime-based plasters, lime-based plasters, clay plasters, silicate plasters, organic plasters, polymer-modified plasters, etc. This standard does not deal with the following: external finishes; painting and/or preparation; impregnations; structural repair of concrete; prefabricated fibre

29、-reinforced plaster elements. Owing to the many and varied materials and practices and different climatic conditions in Europe it is not possible for certain aspects of the standard to enter into sufficient detail to be fully usable to practitioners in each country. Such guidance to complement, but

30、not alter, any basic European recommendations is given in documentation prepared by each country. Aspects of this European Standard, the basic recommendations of which may need to be complemented, are indicated where they occur by a footnote referencing this clause. 2 Normative references The follow
