Abstract:Conducting reliable measurements with traceability is a basic premise in commercial relations between nations. This role is performed by the national standardization institutes (NMI) and coordinated by the Bureau International des Poids et Mesures (BIPM). The use of Reference Materials (RM) and Certified Reference Materials (CRM) have contributed for decades, mainly to the metal and steel and pharmaceutical industries, providing high-quality measurements and adding value to the products. This research presents the primary standards and guidelines relevant to the definition of RM and CRM for the area of non-destructive testing (NDT) by ultrasound. The generation process of these materials must occur from short and long term stability and homogeneity tests following ISO Guide 35. Following a basic protocol defined for the experiments, the first results generated for the RM and CRM validation process are presented for the first results generated for a production process of a set of 24 carbon steel blocks for property calibration regarding ultrasonic velocity.
Na sua opinião, qual deveria ser o desenvolvimento necessário para que ultrassom fosse largamente utilizado na construção civil?
Acho que o caminho mais adequado é por meio da pesquisa e desenvolvimento. A partir das técnicas ultrassônicas já aplicadas em outras áreas, seja na área de ensaios não destrutivos como na área de saúde, será possível verificar quais os melhores meios de aplicar esta ferramenta já consagrada em tantas aplicações.
