What force testing measures
Force testing measures forces produced when a moving gate encounters a test instrument under specified conditions. An engineer uses the results to assess the relevant protection and to establish a record for later checks. A person pushing against the gate cannot provide an equivalent measurement.
The appropriate procedure depends on the gate, its movement and the protective approach used. This guide explains the questions to ask; it does not provide a test procedure or a set of universal pass values.
Where testing fits into the safety assessment
Force limitation is one possible part of a gate’s protective measures. Where the installation relies on it, the installer needs to verify its performance. Other risks can require different measures, and an acceptable reading at one test point does not establish that the whole entrance is safe.
The assessment also needs to consider trapping and shearing areas, access to moving parts, the people using the entrance and foreseeable behaviour. Read our guide to photocells, edges and loops to understand why devices have different roles.
Why one force number is not enough
Force limits and test methods relate to defined conditions, positions and time periods. Presenting a number as a continuous safe pressure, or assuming the same value applies at every edge, loses that context. Do not use a simplified web table to approve an installation.
Ask the engineer which current standard or other technical approach supports the assessment, which risks the tests address and how the results will be recorded. They should have the competence and equipment for the work. Changes to force or sensitivity settings should not be a homeowner troubleshooting step.
What to request in the report
Ask the report to identify the entrance and equipment, the date and person doing the work, the checks undertaken, any limitations, findings and required actions. Where force tests are relevant, request the recorded results and their assessment in context.
Keep these records with the user instructions and handover documents. A statement that the gate opens and closes is not a substitute for a safety assessment. If an unsafe condition is identified, ask how the entrance should be kept out of use and what must happen before it can operate again.
When to arrange an assessment
Arrange advice after damage, unexpected movement, a suspected failure of a protective function or a change to the gate or drive. Follow the checking arrangements specified for your system. The requirements for a business or rented property may differ from those of a privately owned domestic entrance.
See our responsibilities guide. Avoid treating a fixed annual date as either a complete safety guarantee or a universal statutory requirement for all private homeowners.
Leave adjustments and powered tests to a competent person
Do not test the closing force with your body, a pet, a vehicle or improvised objects. Keep people clear if you suspect a fault and follow the supplied instructions for taking the gate out of use, provided that can be done safely.
