Reference Base to Ensure Uniformity in Measurements of Ultrasound Wave Propagation Parameters in Solids in Far Eastern Branch VNIIFTRI

P. V. Bazylev, I. Y. Krumgolts, V.A. Lugovoy

The paper presents the national primary standard for propagation speeds and attenuation coefficient for ultrasound waves in solids and the national working standard for propagation speeds and attenuation coefficient for ultrasound waves in solids — an arrangement for the integrated measurements of solids acoustical parameters as per GOST Р 8.756-2014. Measurement methods are described. Standard systems metrological performance is provided.
Keywords: longitudinal waves, shear waves, surface waves, optical method, capacitive method, non-contact method, echo-pulse method, resonance method, initial measures, verification scheme.
