Gate force testing

Chiltern Technology only installs electrically powered gates that meet BS EN 12445:2001. legislation. This defines the forces generated by a gate, which may meet a person or an obstacle while in operation. Our gates sense people automatically and will stop or reverse to avoid risk of injury. We also provide regular testing to ensure continued compliance.

These are the things we do when installing or modifying electrically powered gates in areas that people have access to. They might also apply to you if you maintain gates.

  • You need the right test equipment to measure closing/opening forces. If you do not have this equipment, you cannot be sure that the gates meet safety standards.
  • When they are opening and closing, the force of the gates should be limited to those in the British/European standards. The gates should also reverse if they hit someone or something.
  • The gates should have sensors that can stop them if someone has been detected. This could be light beams (photoelectric devices), which stop the gates before they reach an obstacle.
  • If there are parts of the gates where someone could become trapped or get crushed while it is moving, these need be protected. People could get injured, for example, as the bars of the gates pass the gate post.
  • The gates must have an emergency release mechanism incase someone gets trapped.

When we have installed gates safely and met all of the relevant safety requirements we can apply a CE Mark, so people can be confident the job has been done properly. We also keep details of the installation, and of any tests, in a technical file.

Standard: BS EN 12453:2001

BS EN 12453:2001 recommends a minimum level of safeguarding against the crushing hazard at the closing edge of the gate, depending on the type of environment in which the gate is operating. The Standard defines 3 types of use:

  • Type 1 - The gate is only used by trained users and there is no intended, inadvertent or unauthorised access to it by members of the public.
  • Type 2 - A limited group of persons (for example persons sharing a block of flats) are trained to operate the gate and the gate is located in a public area.
  • Type 3 - Any person is free to operate the gate and the gate is in contact with the general public.

The Standard advises on the minimum levels of safeguarding of the main edge according to its type of use. Type 1 gates are not considered further in this safety notice because they are not located in the vicinity of the general public.

In the case of those powered gates categorised as Type 2 or Type 3 and which have automatic control, the advised level of safeguarding is to:

Limit forces according to Annex A of the Standard using force limitation devices or sensitive protective equipment


Provide a means for the detection of the presence of a person or an obstacle standing on the floor at one side of the gate.

Alternatively, a means for detection of the presence a person, which is designed in a way that in no circumstances can that person be touched by the moving gate leaf, can be provided.
