2 Suchassessment is beyond the scope of this Europeanstandard (see EN 1634-1).Digit 5 SafetySingle-axis hinges are required to satisfy the essentialrequirements of safety in use. Therefore, only grade 1 best practice guide : Single-axis hinges to BS EN 1935 ABHM best practice GUIDESThis publication is one in a series of guidesaddressing the major issues that should beconsidered when specifying, ordering or using theproducts it describes. It aims to provide the readerwith a concise document which includes a summaryof relevant sections from the new European productstandard. The reader will then be in a position to seekfurther specialist advice where necessary andrecognise GENUINE conformity to the new standards. BS EN 1935 Single-axis hingesThis standard provides details on product types,classification by use, test cycles, door mass, corrosionresistance, as well as definitions, product performancerequirements, test apparatus, test methods and markingof products.

SCOPEThis European standard specifies requirements forsingle-axis hinges for windows and doors opening inone direction only, whose rotation axis is no more than30mm from the face of the sash or door. It covers bothfixed pin and lift-off hinges, and contains additionalrequirements for hinges intended for use on fire doors. CLASSIFICATIONBS EN 1935 classifies door furniture by using an 8 digitcoding system. A similar classification applies to allbuilding hardware product standards so thatcomplementary items of hardware can be specified to,for instance, a common level of corrosion resistance,category of use, etc.

4 Each digit refers to a particularfeature of the product measured against the standard'sperformance ABHM 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 and Box:-The icon above is for a product which meets Grade 2 inthe Category of Use classification, where EN 1935stipulates a range of four possible grades from 1 to 1 Test door mass gradeDoor mass010 kg120 kg240 kg360 kg480 kg5100 kg6120 kg7160 kg2(1-4)BoxRange/OptionsGrade/TypeSymbol MARKINGEach single-axis hinge manufactured to this Europeanstandard must be marked with the following:(a) manufacturer s name or trademark, or other meansof identification.(b) the hinge grade (eighth digit of classification code).(d) number of this European : This information can be in coded form CE MARKINGS ingle axis hinges intended for use on fire resistingdoors and smoke control doors are covered by aConstruction Products Directive mandate issued bythe European Commission.

5 Consequently, thisstandard is regarded as a harmonised standard andcompliance with it, supported by suitable evidence,allows the application of the CE fire/smoke door hinges have a critical safetyfunction, application of the CE mark will require theinvolvement of a notified certification body to provideverification of the compliance claims. This will involveinitial type-testing of the product to EN 1935, initialinspection of the manufacturer s factory productioncontrol and continuing surveillance and approval ofthe factory production control. On satisfactorycompletion of these tasks, the notified body issues anEC Certificate of Conformity which then permits themanufacturer to declare compliance and affix the CEmarking to his product. The standard requires the following additionalinformation to accompany the CE marking:- the identification number of the notified certificationbody the name or identifying mark of the manufacturer the registered address of the manufacturer the last two digits of the year in which the markingwas applied the number of the EC certificate of conformity reference to EN 1935:2002 the classification code of the product 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 6 Corrosion resistanceFive grades of corrosion resistance are identified inaccordance with EN 1670:- grade 0: no defined corrosion grade 1: mild grade 2: moderate grade 3: high grade 4: very high 7 SecurityTwo grades of security are identified for single-axishinges.

6 - grade 0: not suitable for use on burglar-resistant doorassemblies- grade 1: suitable for applications requiring a degree ofsecurity. Annex C of this European standard details thehinge grade to use for the level of security 8 Hinge gradeFourteen grades are identified in this Europeanstandard and are detailed in Table 2 below. The fullclassification is shown in the standard. EXAMPLEE xample: the following marking denotes a single-axishinge for use in medium duty situations, tested to 200000 cycles, for use on doors with a mass up to 60 kg,with stated fire door suitability, satisfying the essentialrequirement of safety in use, high corrosion resistance,suitable for burglar-resistant doors and with a hingegrading of 10.

8 For example, a minimum of information could appear on the product itself, with the complete information appearing on the installation instructions or on the accompanying commercial documents. Where the information is split in this way, the location(s) lower in the hierarchy must always repeat that part of the information already placed higher up in the hierarchy. Formed in 1897 to represent the interests of brassfounders, theABHM and its members has been instrumental in the industry sadvancement over the last 100 in material and manufacturing technologies as wellas changes in the building industry throughout the world haveresulted in the development of a wide range of new productsand practices . These advances have, in turn, required newskills and knowledge from the designer and manufacturer ofthe products themselves through to the specifiers, stockists andinstallers in the various sectors of the building Association and its members have consistently risen to thischallenge, creating products which meet the needs of achanging world and developing performance standardsalongside national and international organisations, such as BSIand CEN, which enable the industry to select and comparehardware with advances made throughout the industry are reflected inthe Association s structure, the diversity of its membership andthe wide range of activities in which it is involved.
