CEN/TC 125/WG 2 - Mortar

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.

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 buildings and civil engineering works).
This European Standard defines for fresh mortar the performance related to workable life, chloride content, air content, density and correction time (for thin-layer mortar only). For hardened mortar 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 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 covers masonry mortars defined in Clause 3 with the exception of site made mortar. 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 mortar.

This European Standard is applicable to factory-made rendering/plastering mortars based on inorganic binders for external (rendering) and internal (plastering) use on walls, ceilings, columns and partitions. It contains definitions and final performance requirements.
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.
It does not cover mortars where calcium sulphate binder is the principal active binding agent.
Calcium sulphate binder can be used as an additional binder together with air lime. If air lime is the principal active binding component, the rendering/plastering mortar is covered by this European Standard. If the calcium sulphate binder is the principal active binding component, the mortar is covered by EN 13279.
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. plasterboards) 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 mortar.

This European Standard is applicable to mortar containing organic polymer binding agents as the principal binder used for external rendering and internal plastering. It contains definitions, applications properties and final performance requirements. Fire resistant and acoustical mortars, mortars for structural repair and surface treatments of building elements such as materials for smoothing or trueing, paints or similar coatings and prefabricated units (e.g. plaster boards) are not dealt within this standard.

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. This European Standard is also applicable to renders and plasters with inorganic  binders such as silicates, silanes, siloxanes and silicones.

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 European Standard or part of this European Standard may be used in conjunction with codes of applications and national specifications covering site made mortars.

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.

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.

TC - Modification to Table ZA.1

This part of EN 998 specifies requirements for masonry mortars (bedding, jointing and pointing) for use in masonry (e.g. facing and rendered masonry, loadbearing or non-loadbearing masonry structures, including internal linings and partitions, for building and civil engineering).

This EN is applicable to mortar for external rendering and internal plastering. It contains definitions, application properties and final performance requirements. It does not cover mortars where calcium-sulphate binder is the principle active binding agent. Calciumsulphate 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 standard.
