The quality management standard DIN ISO 9001 divided the maintenance management into management of measuring and test equipment and maintaining the organisational infrastructure. In this module, all items requiring inspections can be registered in a central database. For each item a responsible person can be assigned can be assigned, as well as the necessary test types and cycles. Thus, each employee will keep track of the items he is responsible for. An omission of required tests will thus be prevented. In addition, it is possible to add documents, such as e.g. test reports and calibration certificates and link them directly to the documented tests. The quality manager will always have an overview of the tested assets and be able to keep track of all registered items.
