European standard for hinges

EN1935

Building Hardware Single-axis hinges requirements and test methods

This European standard is for mechanical operation, is a series of tests on fastness, strength, weather resistance and function of hinges in use.

Eight-digit codes are generally used, each code representing different indicators and requirements.

The first code, divided into 4 grades according to the intensity of use.

1 level: hinge for door, Careful maintenance during use, little chance of misuse and damage. Such as residence, villa.

2 level:hinge for door, Maintenance during use, some chance of misuse and damage. Such as office building.

3 level:hinge for door, No maintenance during use, more chance of misuse and damage. Such as hospital, library, school.

4 level:hinge for door, a lot of chance of misuse and damage. Such as super market, May be opened by violence, such as prison.

The second code is the usage test for door and window hinges.

Hinge for window

level 3: 10,000 fatigue tests

level 4: 25,000 fatigue tests

Hinge of door

level 4: 25,000 fatigue tests

level 7:200,000 fatigue tests

The third code indicates the door weight

The fourth code is divided into 2 grades according to whether it is suitable for smoke and fire doors.

level 0: Not suitable for smoke and fire doors

level 1: Suitable for smoke and fire doors

The fifth digit indicates the safety of the hinge

level 1:safe to use

The sixth digit code indicates the anti-corrosion and weather resistance level

level 0:No anti-corrosion and weather resistance requirements

level 1:General anti-corrosion and weathering requirements

level 2:Medium anti-corrosion and weather resistance requirements

level 3:High anti-corrosion and weather resistance requirements

level 4:Very high corrosion and weather resistance requirements

The eighth digit represents the overall grade of the hinge

Schematic diagram of testing equipment:

  1. swivel hinge
  2. Rail Chute
  3. pneumatic cylinder
  4. The principle is: when the door is opened and closed, the force angle acting on the door does not exceed 90°
  5. load bearing hinge
  6. Optional detection door weight range 10-160kg
  7. Fixing bolts on door frame
