Force and Pressure Testing
Testing the force & pressure of a cobot
During the commissioning stage, 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 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.
As the cobot application is completed, the risk assessment should be closed out, ensuring that all hazards have been adequately reduced.
As the cobot is subject to mechanical wear, testing should be repeated on a periodic basis to ensure that nothing has changed or deteriorated.
"As the cobot application is completed, the risk assessment should be closed out, ensuring that all hazards have been adequately reduced."
UKCA Marking of the 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 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.
