BRITISH STANDARD BS EN 845-1:2003 Specification for ancillary components for masonry Part 1: Ties, tension straps, hangers and brackets The European Standard EN 845-1:2003 has the status of a British Standard ICS 91.060.10; 91.080.30 ? Incorporating Corrigendum No. 1 and Amendment No. 1 Licensed Copy: sheffieldun sheffieldun, na, Tue Nov 07 06:40:58 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 845-1:2003 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 16 September 2003 ISBN 0 580 42606 8 National foreword This British Standard is the official English language version of EN 845-1:2003. EN 845-1 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M116, Masonry and related products, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 845-1 as a “harmonized” European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. The Commission in consultation with Member States has agreed a transition period for the co-existence of “harmonized” European Standards and their corresponding national standard(s). It is intended that this period will comprise a period, usually nine months, after the date of availability of the European Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. EN 845-1 is the subject of transitional arrangements agreed under the Commission mandate. In the UK, the corresponding national standards are: BS 1243:1978, Specification for metal ties for cavity wall construction; BS 6178-1:1990, Joist hangers Part 1: Specification for joist hangers for building into masonry walls of domestic dwellings; DD 140-1:1986, Wall ties Part 1: Methods of test for mortar joint and timber frame connections; and based on this transition period of twentyone months, the above mentioned national standards will be withdrawn in January 2005. NOTEThis date is approximate. Users of this standard should contact BSI Customer Services for confirmation of withdrawal. The UK participation in its preparation was entrusted by Technical Committee B/519, Masonry, and associated testing, to Subcommittee B/519/3, Ancillary components, which has the responsibility to: A list of organizations represented on this subcommittee can be obtained on request to its secretary. aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. © BSI 2006 Amendments issued since publication Amd. No. DateComments 14736 Corrigendum No. 1 1 October 2003Correction to Figure 6 15539Revision of supersession details and addition of NA.5.4 29 September 2006 Licensed Copy: sheffieldun sheffieldun, na, Tue Nov 07 06:40:58 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 845-1:2003 i EN 845-1:2003 has been prepared by CEN/TC 125, Masonry, and immediately supersedes EN 845-1:2001 which is withdrawn (but see also transitional arrangements above in relation to other British Standards). EN 845-1 specifies the characteristics and performance requirements for ties, joist hangers, straps and brackets available throughout the CEN member countries. It aims to do so in product performance terms, avoiding as far as possible prescriptive requirements and all the traditional designations of these products available throughout Europe. Current products, however, will continue to be manufactured, traded and used, even though they are not referred to by name in this European Standard. EN 845-1 includes clauses covering initial type tests, factory production control, sampling for initial type testing and independent testing of consignments. These are similar in all masonry product specifications. The UK National Annex NA attached to this standard provides an informative commentary on the differences between EN 845-1, BS 1243 and BS 6178-1. Nothing in this annex should be construed as specifying requirements other than those contained in the normative parts of this European Standard. If CE marking is performed, the procedures in Annex ZA will apply. The significance of the CE marking is that the product manufacturer claims compliance with the “harmonized” requirements given in the normative text of the product standard. These relate to the essential requirements of the EU Construction Products Directive. Not all product characteristics need necessarily be given on the CE marking, but those product characteristics covered by regulations in force in each EU Member State, where the manufacturer intends that the product will be used, do need to be stated.

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 2003, and conflicting national standards shall be withdrawn at the latest by January 2005. 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 document supersedes EN 845-1:2001. 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. 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, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

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 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.
