BS EN 1935

This is the European standard for the classification of the strength and durability of side hung metal hinges. Hinges are tested against a standard door and number of cycles to achieve certification. A single hinge is tested, whereas in reality a minimum of three hinges will support the door. The chart below shows the various grades.

Hinge Grade Usage Test Cycles Door Mass
1 Window 10,000 10Kg
2 Window 10,000 20Kg
3 Window / Door 25,000 20Kg
4 Door 200,000 20Kg
5 Window 10,000 40Kg
6 Window / Door 25,000 40Kg
7 Door 200,000 40Kg
8 Window 10,000 60Kg
9 Window / Door 25,000 60Kg
10 Door 200,000 60Kg
11 Door 200,000 80Kg
12 Door 200,000 100Kg
13 Door 200,000 120Kg
14 Door 200,000 160Kg


Hinges that are used on fire or escape routes must legally be CE marked. The mark on the product will satisfy building inspectors and trading standards officers that you have done your best to ensure that the building is safe to use. Increasingly it will become the duty of the building owner to ensure that the building is safe to use and this is where CE marked products can help.

CE marking is not easily achieved. Products have to be checked at independent test laboratories and the production is checked within the manufacturing factories. To keep your building safe only use products with this mark.


CERTIFIRE is voluntary third party certification for fire protection products, operated by Warrington Certification. CERTIFIRE tests a huge range of hardware products. CERTIFIRE approved products will all work together on the door assembly to ensure maximum safety against spread of fire. CE marked products do not have the same rigorous certification requirements as CERTIFIRE approved products so to remove any doubt of your chosen hinge and door closer working together on your door assembly make sure that they are both CERTIFIRE approved.

The Disability Discrimination Act 1995 (DDA), is concerned with giving access to all to buildings. The more noticeable changes to buildings are the increasing numbers of disabled toilets. DDA is equally concerned about the ease of opening doors for wheelchair users and for this reason has specified the maximum opening forces for doors. Fire regulations demand all fire doors to close shut to prevent the spread of fire and though they take precedence over DDA can conflict with the DDA requirements. One way of ensuring that doors open easily for wheel chair users and also close to prevent the spread of fire is to use hinges with the lowest possible torque resistance. The European standard for hinges BS  EN 1935 allows a maximum of 4Nm resistance to opening whereas the high quality bearings used in Phoenix high performance hinges will typically operate at less than a 1Nm resistance.
