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.
BS EN 1935 classifies door furniture by using an 8 digit coding system
Four categories of use are identified:
- grade 1: light duty
- grade 2: medium duty - grade 3: heavy duty
- grade 4: severe duty
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
Eight door mass grades related to single-axis hinges are identified in this European standard as shown in Table 1 below.
Table 1
Test door mass grade Door Mass
0 10 kg
1 20 kg
2 40 kg
3 60 kg
4 80 kg
5 100 kg
6 120 kg
7 160 kg
- grade 0: not suitable for fire/smoke resistant door assemblies
- grade 1: suitable for fire/smoke resistant door assemblies s
Single-axis hinges are required to satisfy the essential requirements of safety in use. Therefore, only grade 1 is identified.
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.
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.
Fourteen grades are identified in this European standard and are detailed in Table 2 below. The full classification is shown in the standard.

This standard details performance requirements and test methods in relation to use (abuse), durability, fire resistance, safety in use, corrosion resistance, and security, with information on classification and marking.
BS EN 12051 classifies door and window bolts by using a 7-digit coding system.
Four grades are specified for category of use:
- grade 1: low frequency of use by those with a high incentive to exercise care.
- grade 2: medium frequency of use, primarily by those with some incentive to exercise care
- grade 3: high frequency of use by the public and others with little incentive to exercise care.
- grade 4: subject to frequent violent usage
Four grades are specified as follows:
- grade 1: 2 500 cycles
- grade 2: 5 000 cycles
- grade 3: 10 000 cycles
- grade 4: 50 000 cycles
No requirement
Two grades are identified:
- 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.
Two grades are identified:
- grade 0: no requirement
- grade 1: products shall be capable of operating with a
side load of 250 N on the bolt, and also after a side load of 1000 N has been applied.
Five grades of corrosion resistance are identified
according
- grade 0: - grade 1: - grade 2:
- grade 3: - grade 4:
to BS EN 1670.
no defined corrosion resistance
mild resistance (normally dry interiors) moderate resistance (interiors subject to condensation)
high resistance (damp interior/exterior) very high resistance (polluted exterior - industrial/coastal)
Five grades of security are identified with figures for end load on shoot, resulting projection, resistance to sawing, and sideload on shoot.
Fourteen grades are identified in this European standard and are detailed in Table 2 below. The full classification is shown in the standard.
