FEDERATION

The Door and Hardware Federation (DHF) was created by amerger between the Association of Building HardwareManufacturers (ABHM) and the Door and ShutterManufacturers Association (DSMA), both of which haveestablished excellent reputations in their respective industries,particularly in the area of technical expertise and thedevelopment of performance standards in national andinternational arenas.

The DHF aims to build on these reputations by exploiting thesynergies that exist between the two associations andcombining their technical and financial resources to provide aunified, authoritative voice for the entire industry.

The DHF and its members have consistently risen to thechallenges posed by an ever-changing market, creatingproducts which meet the needs of a changing world anddeveloping performance standards alongside national andinternational organisations, such as BSI and CEN, which enablethe industry to select and compare products with confidence.

The federation now represents the interests of manufacturersand installers of industrial, pedestrian and garage doors as wellas manufacturers of locks and building hardware. It providesprofessionals in all sectors of the building industry with a singlesource for technical expertise and creates a more powerful andrepresentative lobbying force, with the ultimate aim of assuringprogress and maintaining standards throughout the industry,x

• SUPPORT SERVICEThe correct installation of locks, latches and lockingplates is essential to ensure that they are able tooperate efficiently within the performance levelsdescribed in this standard. Specialist advice isavailable from ABHM members in support of theirproducts from specification stages through supply toeffective operation on site.

• CONFORMITYConformity to the standard must be clearly andunequivocally stated. Such phrases as "tested to ...","designed to conform to ...", "approved to ...", are notsufficient. To avoid misleading or confusing claims itis recommended that one of the following phrases isused when stating conformity:

a) This product has been successfully type-tested forconformity to all of the requirements of BS EN 12209.Test reports and/or certificates are available upon request.

b) This product has been successfully type-tested forconformity to all of the requirements of BS EN 12209including the additional requirements for fire/smokedoor use*. Test reports and/or certificates areavailable upon request.*Add as appropriate.

c) This product has been successfully type-tested forconformity to all of the requirements of BS EN 12209including the additional requirements for fire/smokedoor use*. Regular audit testing is undertaken. Test reports and/or certificates are available uponrequest.*Add as appropriate.

• QUALITY ASSURANCEThe internationally recognised standard for qualityassurance, BS EN ISO 9000 provides confidence thatthe products are being manufactured to a consistentquality level. All ABHM members operate recognisedBS EN ISO 9000 Quality Assurance Schemes.

Additional important considerations

In addition to ensuring that products satisfy therequirements of this standard, other factors should betaken into consideration when selecting locks, latchesand locking plates. These not only include sourcingproducts from a reputable manufacturer, but also qualityassurance, support services and unequivocal conformityto the standard as detailed below:

British Hardware FederationBHF represents some 3,500 ironmongery, hardware and DIYshops in the United Kingdom. In addition, it embraces theIndependent Builders Merchants Service, a specialist division ofthe Federation.

Builders Merchants’ FederationThe Builders Merchants’ Federation represents the majority ofbona fide merchants in the UK. Its members have a combinedturnover of £6 billion a year. Members range from large nationalsto small independents.

Guild of Architectural IronmongersFounded in 1961, the Guild represents 95% of bona fide distributorswithin the UK and the majority of manufacturers of architecturalironmongery. The Guild serves to further all aspects of architecturalironmongery by promoting the interchange of information toencourage better product design and high professional standards ofironmongery scheduling and specification.

Master Locksmiths AssociationThe MLA is recognised by the Home Office, Police and The BritishStandards Institution as being the authoritative body forlocksmithing. It was formed to promote the membership to Centraland Local Governments, Industry, Commerce and the Public.

• MARKINGThe labelling, packaging or accompanying literatureshall show the following: -

a) Manufacturer’s name, trademark or other means ofpositive identification

b) Clear product identificationc) Classification according to the 11-box classification

codingd) Number and year of this European standard (i.e. BS

EN 12209:2003)

• CE markingMechanically operated locks and latches intended foruse on fire/smoke control doors within the EEA* arecovered by a Construction Products Directivemandate issued by the European Commission.Consequently, this standard is regarded as“harmonised” and compliance with it, supported bysuitable evidence, allows for the application of the CEmark.

As such, locks and latches have a critical safetyfunction. Application of the CE mark will require theinvolvement of a notified body to provide verificationof the compliance claims. This involves initial typetesting of the product to EN 12209 and EN 1634-1,initial inspection of the manufacturer’s factoryproduction control and continuing surveillance andapproval of the factory production control. Onsatisfactory fulfilment of these tasks, the notified bodyissues an EC Certificate of Conformity which thenpermits the manufacturer to declare compliance andaffix the CE mark to his product.

* EEA = European Economic Area including the EUand EFTA (except Switzerland).

The CE conformity marking symbol, in letters at least5 mm high, and items i) to vii) below, shallaccompany the product and shall be included ininstallation instructions: -

i) Identification number of the certification body;ii) The name or identifying mark of the produceriii) Registered address of the produceriv) The last 2 digits of year in which the marking wasappliedv) The number of the EC Certificate of Conformityvi) Reference to this European Standard EN 12209)vii) The designation and performance of the lock orlatch according to the 11-box classification codingwhere incorporated in the Scope and clauses of theStandard applying to the essential characteristics

Additionally, at least the CE marking symbol and theidentification number of the certification body shallbe affixed to the lock/latch and optionally on itspackaging

Note that, although the notified body has to beinvolved to verify the manufacturer’s claims, themanufacturer remains responsible for designing andproducing the product, for affixing the CE marking,and for ensuring that the product meets therequirements of the Directive.

Digit 5Safety

No requirement, but note: a lock or latch conforming tothis standard can, at the same time, also be part of anexit device conforming to EN 179 or EN 1125.

Digit 6Corrosion resistance

Eight grades are identified with neutral salt-spray (NSS)corrosion resistance grades from EN 1670:1998, withand without temperature resistance as shown: -

Digit 7Security and drill resistance

Seven grades are identified with minimum figures forrequirements relating to physical attack, with or withoutdrilling of the lockcase, as shown: -

Digit 8Field of door application

Fifteen grades are identified for differing applications –hinged or sliding doors with rim or mortice locks witheither keyless egress from inside or key locking fromboth sides. The grading determines which application isappropriate. In addition, there is a requirement thatlock/latch should not be removable from outside or, forgrades K to R, from inside using “standard” tools.Grades H and P require support for the lockcase wheninstalled.

Digit 1Category of use

Three categories of use are identified:

- grade 1: low frequency of use by people with a highincentive to exercise care and a small chance ofmisuse, e.g. internal residential doors- grade 2: medium frequency of use by people withsome incentive to exercise care but where there issome chance of misuse, e.g. internal office doors- grade 3: high frequency of use by public or others withlittle incentive to exercise care and with a high chanceof misuse, e.g. public doors

Digit 2Durability

Twelve grades are identified with minimum figures fordeadbolt and snib operation, and latch bolt operationwith and without side load, as shown. The side load isapplied to the latch bolt when it is being withdrawn

Digit 3Door mass and closing force

Nine grades are identified with maximum figures forclosing force at various door masses as shown.Note: closing force is from a standing start: i.e. fullyextended latch bolt in contact with striking plate at startof test

Digit 4Fire resistance

Two grades are identified: -

–grade 0: not approved for use on fire/smoke doorassemblies- grade 1: suitable for use on fire/smoke doorassemblies tested to EN 1634-1 etc.Note 1. A grade 1 classification means only that the lockhas been designed for use on fire/smoke control doors;the actual fire performance achieved (e.g. fire integrityof 30 minutes on a partially glazed timber door etc.) willbe contained in a separate fire test report.

Note 2. Where a product is intended for fire/smoke dooruse (i.e. a “1” in box 4), it must be possible todemonstrate compliance with the EssentialRequirements of the Construction Products(Amendments) Regulations. It is recommended that theproduct should bear the CE mark (see section on CEmarking).

• CLASSIFICATIONBS EN 12209 classifies mechanically operated locks,latches and locking plates using an 11 digit codingsystem. This has proved necessary in order to provide aproper assessment of all the varied features of productsfor specific markets within Europe. It should be notedthat to avoid a greater proliferation of boxes, certainfeatures have been “doubled up”: e.g. durability anddurability with side load; door mass and closing force;corrosion resistance and temperature resistance. Thesystem is comprehensive but it has led to the use ofletters (rather than numbers) in certain boxes, sincethere can only be one digit in each classification box. Asimilar classification system applies to all buildinghardware product standards (at least for the first 7boxes) to aid meaningful comparisons with relatedproducts.

The DHF recommends the use of graphic icons toenhance clarity of information and has devised a systemto facilitate assimilation of the various productclassifications. Each feature within the productclassification is represented by an icon comprising fourelements; Symbol, Grade/Type, Range/Options andBox:-

The icon above is for a product which meets Grade 2 inthe Category of Use classification, where EN 12209stipulates a range of three possible grades from 1 to 3.
