# Liability

Many events in the operating environment may affect the tightening process and shall require a validation of results. In compliance with applicable standards and/or regulations, we hereby require you to check the installed torque and rotational direction after any event that can influence the tightening result. Examples of such events include but are not limited to:

- initial installation of the tooling system

- change of part batch, bolt, screw batch, tool, software, configuration or environment

- change of air- or electrical connections

- change in line ergonomics, process, quality procedures or practices

- changing of operator

- any other change that influences the result of the tightening process

The check should:

- Ensure that the joint conditions have not changed due to events of influence.

- Be done after initial installation, maintenance or repair of the equipment.

- Occur at least once per shift or at another suitable frequency.
