95771 - PROVE DEI MATERIALI E DIAGNOSTICA P

Learning outcomes

At the end of the Materials Testing and Diagnostics course, the student knows the techniques for conducting tests on materials and building components, including how to take samples and characterize materials for existing buildings. He is also familiar with the basic elements of European certification of component for buildings and construction, ad well as the quality control.
