Conservation of cultural heritage. Cleaning of porous inorganic materials. Laser cleaning techniques for cultural heritage Ingestion-build-100998 Boron trifluoride proportional pulse counter1 Scope This European standard applies to porous inorganic materials constituting cultural heritage. It provides the fundamental requirements of the laser parameters and guidelines for the choice of the laser operational parameters, in order to optimize the cleaning procedure.
