Foreword
This document (prEN 845-1:2010) 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 CEN Enquiry.
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.
In this European Standard the Annexes A and B are normative.
This Part has been modified, including the introduction of additional requirements, taking into account
the detailed answer by CEN/TC 125 to EC mandate M116 for masonry as well as details of the
relationship of this new harmonized European Standard with the EU Directives.
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.

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) ferritic stainless steel;
3) copper;
4) phosphor bronze;
5) aluminium bronze;
6) zinc-coated-steel with or without organic coating;
7) polypropylene;
8) polyamide (for expansion plugs only).
NOTE The resistance 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

publications. These normative references are cited at the appropriate places in the text and the
