Understanding BS EN 1935 Single-axis hinges grades

Single-axis hinges to BS 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.


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.


Category of useDigit 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

DurabilityDigit 2
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

door massDigit 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.

Suitability for fire/smoke door useDigit 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).

SafetyDigit 5
Single-axis hinges are required to satisfy the essential requirements of safety in use. Therefore, only grade 1 is identified.

Corrosion resistanceDigit 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.

SecurityDigit 7
Two grades of security are identified for single-axis
- 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.

Hinge gradeDigit 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.

Example of D&D Hardware CE certified butt hinge:

The following marking denotes a single-axis hinge for use in medium. heavy and severe duty situations, tested to 200 000 cycles, for use on doors with a mass up to 120 kg, with stated fire door suitability, satisfying the essential requirement of safety in use, very high corrosion resistance, not suitable for burglar-resistant doors and with a hinge grading of 13.

 hinge certificate


Each single-axis hinge manufactured to this European
standard must be marked with the following:
(a) manufacturer’s name or trademark, or other means of identification.
(b) the hinge grade (eighth digit of classification code).
(d) number of this European standard.
Note: This information can be in coded form
