BS EN 13914-1:2016/COR1外部抹灰和内部抹灰的设计、制备和应用 第1部分:外部渲染
BS EN 13914-1:2016/COR1 specifies requirements and recommendations for the design, preparation and
application ofrenders 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 15824on all common types of backgrounds. It includes 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:the use and application of special renders for liquid retaining structures, e.g. coatings, and for
backgrounds to cladding systems;the structural repair of concrete;the installation of external thermal insulation composite systems (ETICS);the specification and use of sealants used to seal joints for use with rendering;the use of 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 traditions. 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.renders on historical monuments or buildings in protected areas which may be regulated by
national codes;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 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 complemented are indicated where they occur
by a footnote referencing this clause.Cross References:EN 197-1EN 413-1EN 459-1EN 934-3EN 998-1:2010EN 1008EN 1996-2EN 10088-1EN 10346EN 12878EN 13055EN 13139EN 13496EN 13658-2EN 15824:2009EN ISO 1461ISO 1461EN ISO 16120-2ISO 16120-2EN 1015-18EN 1062EN 1504EN 1992-1-2EN 1993-1-2EN 1994-1-2EN 1995-1-2EN 1996-1-2EN 12811-1Incorporates the following:Corrigendum
