EN 998-2:2003 (E)
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.
