BS EN 1935
BS EN 1935 Single-axis hinges
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.
Classification
BS EN 1935 classifies door furniture by using an 8 digit coding system
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 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
Digit 4 Suitability for fire/smoke door use
- grade 0: not suitable for fire/smoke resistant door assemblies
- grade 1: suitable for fire/smoke resistant door assemblies s
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 below. The full classification is shown in the standard.
