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.
