“…𝟐 * 𝑳 𝒕 [1] where: Thus, as mentioned, the determination of the ultrasonic velocity requires only the dimensional and temporal quantities. However, this research also carried out mass measurements of each of the samples, aiming to determine their mass variations and allow to follow the evolution of the densities of the pieces throughout the study.…”

“…This standardization is guaranteed by the traceability of the physical properties measured and propagated by the National Metrology Institutes (NMI). Acting in the calibration of primary standards or distribution of Reference Materials (RM) and Certified Reference Materials (CRM), they have contributed for years in the production of high-quality measurements and adding value to products [1]. In the area of non-destructive testing (END) by ultrasound, it is no different.…”

“…The performance of ultrasonic measurements made using RM and previously calibrated devices guarantees the reliability of the generated results and allows for more informed decision-making. And in the case of CRM, since a calibration certificate backs these with international traceability, they allow adding even more quality to the results [1] [5]. This work addresses the basic procedures for carrying out the feasibility study, planning and production of RM and CRM for metallic blocks of carbon steel, considering the physical property of the ultrasonic velocity of the longitudinal wave.…”

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 pharmaceutical and biological products industry, 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.
