Graf Hardware
The standard provides details on product types, classification by use, test cycles, door mass, corrosion resistance, as well as definitions, product performance requirements, test apparatus, test methods and marking of products. In addition, the published standards include annexes illustrating the various points made through diagrams and supplementary text.
Products included within the standard are illustrated below and include a wider range than covered by BS6459.
BS EN 1154 classifies door furniture by using an 6 digit coding system. A similar classification applies to all building hardware product standards so that complementary items of hardware can be specified to, for instance, a common level of corrosion resistance, category of use, etc. Each digit refers to a particular feature of the product measured against the standard's performance requirements.
For all internal and external doors for use by the public, and others, with little incentive to take care, i.e. where there is some chance of misuse of the door. - grade 3: For closing doors from at least 105° open - grade 4: For closing doors from 180° open Note 1: Grade 4 classification assumes standard installation according to the manufacturer’s instructions. Note 2: For applications subject to extremes of abuse, or for particular limitations of opening angle, door closers incorporating a backcheck function or provision of a separate door stop should be considered.
Only one test duration is identified for door closers manufactured to this standard: - grade 8: 500 000 test cycles
Seven test door mass grades and related door closer power sizes are identified according to table 1 of this standard. Where a door closer provides a range of power sizes both the minimum and the maximum sizes shall be identified.
Two grades of fire behavior are identified for door closing devices manufactured to this standard: - grade 0: Not suitable for use on fire/smoke door assemblies - grade 1: Suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the contribution of the door closer to the fire resistance of specified fire/smoke assemblies. Such assessment is outside the scope of this European Standard (see EN 1634-1).
All door closers are required to satisfy the Essential Requirement of safety in use. Therefore only grade 1 is identified.
Five grades of corrosion resistance are identified according to EN 1670: - grade 0: No defined corrosion resistance - grade 1: Mild resistance - grade 2: Moderate resistance - grade 3: High resistance - grade 4: Very high resistance
Door closers intended for use on fire resisting doors and smoke control doors are covered by a Construction Products Directive mandate issued by the European Commission. Consequently, this standard is regarded as a “harmonised” standard and compliance with it, supported by suitable evidence, allows the application of the CE mark.
