ABSTRACT: The dimension stone qualification through the use of non-destructive tests
(NDT) is a relevant research topic for the industrial characterisation of finite products,
because the competition of low-costs products can be sustained by an offer of highqualification
and a top-guarantee products. The synthesis of potentialities offered by the NDT
is the qualification and guarantee similar to the well known agro-industrial PDO, Protected
Denomination of Origin. In fact it is possible to guarantee both, the origin and the quality of
each stone product element, even through a Factory Production Control on line. A specific
disciplinary is needed. A research developed at DICMA-Univ. Bologna in the frame of the
“OSMATER” INTERREG project, allowed identifying good correlations between destructive
and non-destructive tests for some types of materials from Verbano-Cusio-Ossola region. For
example non conventional ultrasonic tests, image analysis parameters, water absorption and
other measurements showed to be well correlated with the bending resistance, by
relationships varying for each product. In conclusion it has been demonstrated that a nondestructive
approach allows reaching several goals, among the most important: 1) the
identification of materials; 2) the selection of products; 3) the substitution of DT by NDT.
Now it is necessary to move from a research phase to the industrial implementation, as well as
to develop new ND technologies focused on specific aims.
