BS EN 845-1:2013+A1:2016

EN 845-1:2013+A1:2016 (E)

1 Scope
This European Standard specifies requirements for wall 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.
This European Standard is not applicable to:
a)

anchors and fasteners other than as part of an ancillary component;

b)

shelf angles;

c)

wall starter plates for tying into existing walls;

d)

products formed from materials other than:
1)

austenitic stainless steel (molybdenum chrome nickel alloys or chrome nickel alloys);

2)

austenitic ferritic stainless steel;

3)

ferritic stainless steel;

4)

copper;

5)

phosphor bronze;

6)

aluminium bronze;

7)

zinc-coated-steel with or without organic coating;

8)

polypropylene;

9)

polyamide (for expansion plugs only).

NOTE
The resistance to fire performance of the products included herein cannot be assessed
separately from the masonry element of which they are part and is therefore not covered under the scope
of this part of this European Standard.

3 Terms, definitions and symbols
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE

Dimensions and terms relating to wall ties are given in Figure 1.

3.1.1
asymmetrical tie

1) wall tie which is of a different physical design at either end over its embedment depth (or

end fixing) and for which the centre section may be symmetrical or asymmetrical in detail
Note 1 to entry:

Examples are given in Figure 2 a).

2) wall 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

bracket

device attached to structural elements, comprising an individual support for two adjacent
masonry units, which form part of a masonry wall
Note 1 to entry:

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
Note 1 to entry:

Examples are given in Figure 2 and Figure 4.

Note 2 to entry:
Wall ties are further sub classified as asymmetrical or symmetrical and as horizontal,
slope-tolerant or movement-tolerant. Examples are given in Figures 2 , 4 and 5 respectively.

3.1.6
minimum embedment length

minimum length to achieve the declared value of a wall tie, or hanger designed to be embedded
in mortar

Note 1 to entry:
The specification for the length to be built into the wall should be greater than the
minimum used by the manufacturer for the declaration, so as to allow for tolerances in positioning on site
(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

3.1.8
horizontal wall tie

the mortar joint across a cavity
Note 1 to entry:

Examples are given in Figure 2 and Figure 4.

3.1.13
vertical load capacity

mean of the load capacities of the number of joist hangers/brackets tested

3.1.14
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 1 to entry:

Examples are given in Figure 8 and Figure 9.

3.1.15
profile height

maximum overall height (distance between the upper and lower surface at right angles to the
length and width of the joint) of the embedded portion of a wall tie, strap or hanger
Note 1 to entry:

See Figure 1.

3.1.16
shear tie

wall tie designed to transmit shear, tension and compression forces between two adjacent
sections of masonry or between structural frames and masonry
Note 1 to entry:
Figure 10.)

Shear ties are sub-classified as symmetrical or asymmetrical. (Examples are given in

1) A convention has been adopted in this standard for terminology relating to the term ‘load capacity’. It is also used
in the EN 846 (all parts) test methods, which support EN 845. This term without a preceding qualifying adjective as
shown in 3.1.11 denotes an individual value of ‘load capacity’, i.e. the result of one measurement on one specimen.
Where the term is used with a preceding qualifying adjective, e.g. ‘tensile load capacity’ (see 3.1.12), this relates to the
mean of the load capacities from a number of specimens tested.
