Introduction
The properties of rendering and plastering mortars depend essentially on the type or types of binders
used and their respective proportions. Special properties can be achieved by the type of aggregates,
admixtures and/or additions used.
Rendering/plastering mortars are defined
a) according to the concept as either:
designed mortars; or
prescribed mortars.
b) according to the mode of manufacture as either:
factory-made mortars;
semi-finished factory mortars; or
site-made mortars.
c) according to the properties and/or use, as either:
general purpose rendering/plastering mortar;
lightweight rendering/plastering mortar;
coloured rendering mortar;
one-coat rendering mortar;
renovation rendering/plastering mortar;
thermal rendering/plastering insulating mortar.
Rendering/plastering mortars do not attain their final characteristics until properly hardened after
application. The functions performed by a rendering/plastering mortar depend on the properties of the
type of materials used, on the thickness of the coats and the type of application. In addition,
rendering/plastering mortars determine the surface of the construction.
Regional differences in construction practices and climate, and different constituents for
rendering/plastering mortars do not allow for the establishment of standard mix proportions for
prescribed mortar that would be applicable in all of Europe. Therefore, the specification of such mix
proportions (recipes) and fields of application should be based on practice and experience available in
the place of use.

8.1 General
Conformity assessment is needed to demonstrate, by Initial Type Testing, ITT (8.2), that the product
complies with the requirements of this European Standard and that the performance declarations
represent the true behaviour of the product and, by Factory Production Control, FPC (8.3), that the
performance declarations based on initial type testing results remain valid for subsequent products.
The manufacturer (or his agent) shall demonstrate the compliance for his product with the
requirements of this European Standard by carrying out both ITT and FPC and is responsible for the
product being in compliance with all the provisions.
8.2 Initial type testing, ITT
8.2.1 General

FprEN 998-1:2010 (E) 3 Foreword This document (FprEN 998-1:2010) has been prepared by Technical Committee CEN/TC 125 “Masonry”, the secretariat of which is held by BSI. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 998-1:2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports the essential requirements of the EU Construction Products Directive (89/106/EEC). For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this document. EN 998 Specification for mortar for masonry consists of: Part 1: Rendering and plastering mortar. Part 2: Masonry mortar.

FprEN 998-1:2010 (E) 4 Introduction The properties of rendering and plastering mortars depend essentially on the type or types of binders used and their respective proportions. Special properties can be achieved by the type of aggregates, admixtures and/or additions used. Rendering/plastering mortars are defined according to the concept as either: designed mortars; or prescribed mortars. according to the mode of manufacture as either: factory-made mortars; semi-finished factory mortars; or site-made mortars. according to the properties and/or use, as either: general purpose rendering/plastering mortar; lightweight rendering/plastering mortar; coloured rendering mortar; one-coat rendering mortar; renovation rendering/plastering mortar; thermal rendering/plastering insulating mortar. Rendering/plastering mortars do not attain their final characteristics until properly hardened after application. The functions performed by a rendering/plastering mortar depend on the properties of the type of materials used, on the thickness of the coats and the type of application. In addition, rendering/plastering mortars determine the surface of the construction. Regional differences in construction practices and climate, and different constituents for rendering/plastering mortars do not allow for the establishment of standard mix proportions for prescribed mortar that would be applicable in all of Europe. Therefore the specification of such mix proportions (recipes) and fields of application should be based on practice and experience available in the place of use. kSIST FprEN 998-1:2010

1 Scope This European Standard is applicable to factory made rendering/plastering mortar based on inorganic binders for external (rendering) and internal (plastering) use on walls, ceilings, columns and partitions. It contains definitions and final performance requirements. It does not cover mortars where calcium sulphate binder is the principle active binding agent. Calcium sulphate binder can be used as an additional binder together with air lime. If air lime is the principle active binding component, the rendering/plastering mortar is covered by this European Standard. If the calcium sulphate binder is the principle active binding component, the mortar is covered by EN 13279. The classification is carried out by the producer of the mortar. Special fire resistant- and acoustical mortars, mortars for structural repair and surface treatments of building elements such as materials for smoothing or trueing, paints, coatings, thin-layer organic renders/plasters and prefabricated units (e.g. plaster boards) are not dealt with in this European Standard. This European Standard covers rendering/plastering mortars defined in Clause 3 with the exception of site made rendering/plastering mortars. However, this European Standard or part of this European Standard may be used in conjunction with codes of application and national specifications covering site made mortars. 2 Normative references The following referenced documents are indispensable for the application of this document.
