BS EN 1935 Single-axis hinges
Published：2023-9-19 13:28:10 Read：
◆ EN 1935 This 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 standard includes annexes with details for special applications.
◆ SCOPE
This European standard specifies requirements for single-axis hinges for windows and doors opening in one direction only, whose rotation axis is no more than 30mm from the face of the sash or door. It covers both fixed pin and lift-off hinges, and contains additional requirements for hinges intended for use on fire doors.
◆ CLASSIFICATION
BS EN 1935 classifies door furniture by using an 8 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.
√Digit 1 – Category of use
Four categories of use are identified:
– grade 1: light duty
– grade 2: medium duty
– grade 3: heavy duty
– grade 4: severe duty
√Digit 2 – Durability
Three grades are identified for single-axis hinges manufactured to this European standard:
– grade 3: 10 000 test cycles, for light duty hinges on windows only
– grade 4: 25 000 test cycles, for light duty hinges on windows and doors
– grade 7: 200 000 test cycles, for medium. heavy and severe duty hinges on doors only
√Digit 3 – Test door mass
Eight door mass grades related to single-axis hinges are identified in this European standard as shown in Table 1.
√Digit 4 – Suitability for fire/smoke door use
Two grades of suitability are identified for single-axis hinges:
– grade 0: not suitable for fire/smoke resistant door assemblies
– grade 1: suitable for fire/smoke resistant door assemblies subject to satisfactory assessment of the contribution of the single-axis hinge to the fire resistance of the specified fire/smoke door assemblies. Such assessment is beyond the scope of this European standard (see EN 1634-1).
√Digit 5 – Safety
Single-axis hinges are required to satisfy the essential requirements of safety in use. Therefore, only grade 1 is identified.
√Digit 6 – Corrosion resistance
Five grades of corrosion resistance are identified in accordance with 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.
√Digit 7 – Security
Two grades of security are identified for single-axis hinges:
– grade 0: not suitable for use on burglar-resistant door assemblies
– grade 1: suitable for applications requiring a degree of security. Annex C of this European standard details the hinge grade to use for the level of security required.
√Digit 8 – Hinge grade
Fourteen grades are identified in this European standard and are detailed in Table 2. The full classification is shown in the standard.
◆ CE MARKING
Single axis hinges 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.
