Conservator-Restorers have the role of preserving cultural property for the benefit of present and future generations. They contribute to the understanding of cultural property, in respect to its historical significance and physical integrity. Conservator-restorers are responsible for diagnostic examinations, treatments for the conservation and restoration of cultural property and the documentation of these interventions. They may be required to manage an entire restoration site. They have the technical, practical and scientific responsibility of the performed restorations. They respect fundamental ethical standards and contribute to the professional recognition of their workshops through scientific publications.
There are three levels of conservation-restoration: preventive conservation (taking measures to reduce the risk of degradation in the object's environment), curative conservation (direct intervention on the object to stabilise its state), and restoration (direct intervention performed on the object to improve its state, awareness, understanding and usage).
