Alle Eigenschaften werden nach den entsprechend festgelegten Prüfver-fahren, die in gesonderten Europäischen Normen enthalten sind, ermittelt.
Diese Europäische Norm stellt ein Verfahren zum Nachweis der Übereinstimmung der Produkte mit dieser Europäischen Norm zur Verfügung.
Anforderungen an die Kennzeichnung der von dieser Europäischen Norm abgedeckten Produkte sind enthalten.
Diese Norm gilt für Mauermörtel nach Abschnitt 3 mit Ausnahme von Baustellenmörtel. Diese Norm oder Teile davon können jedoch in Zusammenhang mit Anwendungsvorschriften und nationalen Festlegungen auch für Baustellenmörtel angewendet werden.
Définitions et spécifications des mortiers pour maçonnerie - Partie 2: Mortiers de montage des éléments de maçonnerie
La présente Norme européenne spécifie les exigences applicables aux mortiers industriels (de montage, jointoiement et rebouchage) utilisés dans les murs, poteaux et cloisons en maçonnerie (par exemple, maçonnerie apparente ou à enduire, structures de maçonnerie porteuse ou non, destinés au bâtiment et au génie civil).
Pour les mortiers frais, la présente norme définit les performances des propriétés relatives à la durée pratique d'utilisation, la teneur en chlorure, l'air occlus, la masse volumique et le temps ouvert (pour les mortiers de joints minces) et, pour les mortiers durcis, les performances des caractéristiques liées à la résistance à la compression, l'adhérence et la masse volumique. Toutes les performances sont mesurées selon les méthodes d'essai correspondantes définies dans des Normes européennes distinctes.
La présente Norme européenne traite également de l'évaluation de la conformité des produits à la présente norme ainsi que de leur marquage.
La présente Norme européenne s'applique aux mortiers de montage définis à l'article 3, à l'exception des mortiers préparés sur chantier. Toutefois, tout ou partie de cette norme peut être utilisée en association avec des codes de mise en �uvre et des spécifications nationales relatives aux mortiers préparés sur chantier.

Foreword
This document (EN 998-2:2003) has been prepared by Technical Committee CEN/TC125 "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 October 2003, and conflicting national standards
shall be withdrawn at the latest by January 2005.
This document supersedes EN 998-2:2001.
This European Standard 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).
It also takes into account the general rules for reinforced and unreinforced masonry in Eurocode 6.
For relationship with EU Directives, see informative Annex ZA which is an integral part of this
standard.
In this European Standard the Annexes A and C are normative and the Annex B is informative.
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, Czech
Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg,
Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United
Kingdom.
Introduction
The properties required of a mortar are related to its use.
They are considered in two groups viz.: those relating to the fresh, unhardened mortar and those to
the hardened mortar.
To support the aim of achieving a performance-related standard, as far as practicable, the standard
refers only to the properties of the product and not to its method of manufacture, except where this is
unavoidable in the description of the characteristics of the product.
1 Scope
This European Standard specifies requirements for factory made masonry mortars (bedding, jointing
and pointing) for use in masonry walls, columns and partitions (e.g. facing and rendered masonry,
load bearing or non-load bearing masonry structures for building and civil engineering).
This European Standard defines for fresh mortars the performance related to workable life, chloride
content, air content, density and correction time (for thin-layer mortars only). For hardened mortars it
defines e.g. performances related to compressive strength, bond strength, density measured
according to the corresponding test methods contained in separate European Standards.
This European Standard provides for the evaluation of conformity of the product to this European
Standard.
The marking requirement for products covered by this European Standard is included.
This European Standard covers masonry mortars defined in clause 3 with the exception of site made
mortars. However, this standard or part of this standard may be used in conjunction with codes of
applications and National specifications covering site made mortars.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any
of these publications apply to this European Standard only when incorporated in it by amendment or
revision. For undated references the latest edition of the publication referred to applies (including
