Collaborative Robot Force And Pressure Testing

When a collaborative robot is using the power and force limiting function (PFL) as a risk reduction method, force and pressure testing is required to validate the contact scenarios.

The amount of force and pressure that can be exerted in a collision could result in injury. Different parts of the body can receive different forces and pressures, as detailed on ISO TS 15066.

If you are unsure as to whether your cobot application is safe, get in touch with our experienced team, and put your mind at ease! 

Validating a cobot application

Our cobot force and pressure testing service enables us to accurately measure the quasi-static and transient contacts identified and highlighted during the cobot risk assessment and ensure that the values are below limit thresholds specified in ISO TS 15066. 

During the commissioning stage, if a collaborative robot is using the power and force limiting function (PFL) as a risk reduction method, it is important to validate the forces and pressures that can be exerted by the cobot movements. Annex A of ISO TS 15066 lists the permissible transient and quasi-static contacts (force and pressure values) that can be exerted onto the body. Where the values are above the permissible limits, measures must be put in place to reduce the values to the acceptable level. This is to ensure that in the unlikely event of a collision with the cobot, the operator is unharmed.


Our experienced safety consultant uses specialist calibrated testing equipment to ensure accuracy and reliability of your system. We are committed to providing you with the highest quality of testing services to ensure the safety of your cobot application.

To Ensure Your Cobot Is Safe 

UKCA Marking Of A Cobot Application

A cobot is supplied with a Declaration of Incorporation (DOI) from the manufacturer, as it is considered a partly completed piece of machinery.

This therefore means the system integrator or end user is legally responsible for the overall UKCA / CE marking process including building the technical file and issuing a Declaration of Conformity (DOC) for the cobot application.

If this is something you require assistance with, please get in touch.
