Specification for mortar for masonry - Part 1: Rendering and plastering mortar

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.

lissage, peintures ou revêtements assimilés, enduits organiques en couche mince, et les composants
préfabriqués (tels que les plaques de parement en plâtre) ne sont pas visés par la présente Norme
européenne.
La présente Norme européenne s'applique aux mortiers d'enduits définis à l'Article 3, à l'exception
des mortiers d'enduits préparés sur chantier. Toutefois, tout ou partie de la présente Norme
européenne peut être utilisée en association avec des règles de mise en oeuvre et des spécifications
nationales relatives aux mortiers préparés sur chantier.

Specifikacija malt za zidanje - 1. del: Zunanji in notranji omet

Ta evropski standard velja za tovarniško izdelano malto za ometavanje/štukature na osnovi anorganskih veziv za zunanjo (ometavanje) in notranjo (štukature) uporabo na stenah, stropih, stebrih in pregradah. Vsebuje definicije in končne zahteve za zmogljivost. Ne zajema malt, pri katerih je glavno aktivno vezavno sredstvo vezivo iz kalcijevega sulfata. Vezivo iz kalcijevega sulfata se lahko skupaj z zračnim apnom uporablja kot dodatno vezivo. Če je glavna aktivna vezivna sestavina zračno apno, je malta za ometavanje/štukature zajeta v tem evropskem standardu. Če je glavna aktivna vezivna sestavina vezivo iz kalcijevega sulfata, je malta zajeta v EN 13279. Razvrščanje izvaja proizvajalec malte. Ta evropski standard ne obravnava posebnih ognjevarnih in akustičnih malt, malt za strukturna popravila in površinsko obdelavo gradbenih elementov, kot so materiali za glajenje ali izravnavanje, premazi, tankoplastni organski ometi/mavci in montažne enote (npr. mavčne plošče). Ta evropski standard zajema malte za ometavanje/štukature, opredeljene v Klavzuli 3, z izjemo malt za ometavanje/štukature, narejenih na kraju samem. Vendar pa se ta evropski standard ali del tega evropskega standarda lahko uporablja v povezavi s pravili uporabe in nacionalnimi specifikacijami, ki zajemajo malte, narejene na kraju samem.

Foreword
This document (EN 998-1:2010) has been prepared 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 March 2011, and conflicting national standards shall
be withdrawn at the latest by March 2011.
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 European Standard supersedes EN 998-1:2003.
The main technical changes compared to the previous edition are in relation to thermal conductivity,
where the basis for the declared value has been specified, and in relation to evaluation of conformity,
where more details have been given.
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.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary,
Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

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.
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.
