Resumo
We present results of developing metrological assurance for the measurements of the optical density of an X-ray image based on a set of optical density measures in the range of 0.2 to 6.3. The set has been designed to render one unit of diffuse optical density for densitometers used to measure optical density and estimate the size of defects on X-ray images when inspecting nuclear power facilities, oil and gas enterprises, railway transport, metallurgical and mechanical-engineering plants, etc. Results of calibrating the set of optical density measures with the GET 206-2016 State Primary Standard of the unit of optical density, developed and in operation at VNIIOFI, are presented.
