Foreword
This European Standard 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 October 2001, and conflicting national standards
shall be withdrawn at the latest by December 2001.
Annex A is informative. The annexes B and C are normative.
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) and includes the performance requirements
referred to in the Eurocode for masonry Structures.
In the present state of the art it is not practicable to include a means of verification of compliance
with fire performance requirements for all products covered by this standard. Consequently none
are included.
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, Iceland, Ireland, Italy, Luxembourg,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope
This European Standard specifies requirements for ties, tension straps, hangers and brackets for
interconnecting masonry and for connecting masonry to other parts of works and buildings including
walls, floors, beams, and columns. Where anchors or fasteners are supplied or specified as part of
an ancillary component, the requirements including performance requirements apply to the
complete product.
The following are not covered by this standard:
- fire performance requirements
- anchors and fasteners other than as part of an ancillary component;
- shelf angles;
- wall starter plates for tying-in to existing walls.
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.

3 Terms, definitions and symbols
3.1 Terms and definitions.
For the purposes of this standard the following terms and definitions apply :
NOTE 1 Dimensions and terms relating to wall ties are given in figure 1.
3.1.1 asymmetrical tie :
(1) Tie which is of a different physical design at either end over its embedment depth (or end
fixing). The centre section may be symmetrical or asymmetrical in detail.
NOTE Examples are given in figure 2a.
(2) Tie which is physically identical at either end over its embedment depth (or end fixing) but
which is fixed in a different manner at each end is also defined as asymmetrical for the purposes of
the test procedure.
NOTE Examples are given in figure 2b.

3.1.2 bracket : Device attached to structural elements, comprising an individual support for two
adjacent masonry units, which form part of a masonry wall.
NOTE Examples are given in figure 3.
3.1.3 cavity wall tie : Device for connecting a masonry leaf across a cavity to another masonry leaf
or to a structural frame to resist tension and compression forces while allowing limited differential
movement in the plane of the wall. (Examples are given in figures 2 and 4).
NOTE Wall ties are further subclassified as asymmetrical or symmetrical and as
horizontal, slope-tolerant or movement-tolerant. Examples are given in figures 2, 4
and 5 respectively.

mortar. (see figure 1)
3.1.7 fixing : Device, (e.g. a nail, screw, screw/plug, anchor or bolt) used to connect ancillary
components to masonry or to supporting structures to resist tension and shear forces.
NOTE Examples are listed in Annex A.
3.1.8 horizontal wall tie: Wall tie which is designed to be installed approximately horizontally and

masonry wall by direct loading via a flange which is embedded in a mortar joint.
NOTE Examples are given in figure 7.
3.1.11 load capacity: Mean value for a sample of product specimens of the failure load or load at
an extreme displacement given in the appropriate test method, whichever is the lesser.
3.1.12 movement-tolerant cavity wall tie : Cavity wall tie which is designed to allow large in-plane
differential movements of the walls, without generating large shear stresses, by the use of flexible
body materials, free-running slot systems, articulated joints or other means.
NOTE Examples are given in figures 8 and 9c.

adjacent sections of masonry or between structural frames and masonry.
NOTE Shear ties are subclassified as symmetrical or asymmetrical. (Examples are given in
figure 10).
3.1.15 slip tie (general purpose) : Tie designed to transmit only shear forces between two
adjacent sections of masonry or between masonry a
