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.

In the masonry unit standards and in national legislation, some properties need to be declared based on a certain fractile and confidence level. To demonstrate compliance with that a statistical tool can be used.
The purpose of this Technical Report is to exemplify how a statistical tool can be used in practice. This document should not contradict nor extend the scope of the work and role of a Notified Body, nor impose additional burdens on the manufacturer, beyond those laid down in the Construction Products Regulation and the product standards.
Mechanical and other properties of building materials and components are in the report described by random variables with a certain type of probability distribution. The popular normal distribution (Laplace-Gauss distribution) is given in Annex A. Normal distribution may be used to approximate many actual symmetrical distributions. When a remarkable asymmetry is observed, then another type of distribution reflecting this asymmetry should be considered, leading to a more complex method to demonstrate compliance with the product standard. More information on the normality test of Shapiro-Wilk is given in Annex D.

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 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. )
f)   renders on historical monuments or buildings in protected areas which may be regulated by national codes;
g)   the design and installation of flashings at windowsills and elsewhere.
