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
Note 2 to entry: Examples are given in Figure 2 b).
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 1 to entry: Examples are given in Figure 3.
3.1.3

confident of achieving bearing in mind the variability of the manufacturing process
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

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.

FprEN 845-1:2012 (E) 4 Foreword This document (FprEN 845-1:2012) has been prepared by Technical Committee CEN/TC 125 “Masonry”, the secretariat of which is held by BSI. This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 845-1:2003+A1:2008. 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). For relationship with EU Directives, see informative Annex ZA which is an integral part of this standard. This part has been modified to take into account comments made in the five-year review on the 2003 version. A change has been made in the permission to use historic test data when arriving at declared values; a limited permission is also given for the use of calculation methods in certain cases. In view of their widespread use, austinitic ferritic stainless steels have been added to the materials that may be used. EN 845, Specification for ancillary components for masonry, consists of the following parts:
Part 1: Wall ties, tension straps, hangers and brackets; Part 2: Lintels; Part 3: Bed joint reinforcement of steel meshwork. kSIST FprEN 845-1:2012
FprEN 845-1:2012 (E) 5 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. 2 Normative references
