Metrological Assurance of Mechanical Stress Measurements

A. F. Ostrivnoy, A. A. Lobashev

Measurements of mechanical stress are necessary to improve the operational safety of industrial facilities: building structures, oil and gas pipelines, power plant equipment, transport and others.
The works carried out in the D.I.Mendeleyev Institute for Metrology which aimed at creating a standard of mechanical stress are represented. As a result of experimental works with a variety of non-destructive testing devices serious problems have been identified in the way of metrological assurance of measurement of mechanical stress.
It is determined the circle of the problems, which must be solved to ensure the implementation of measurement of mechanical stress on the required by industry levels of reliability and accuracy.
Keywords: mechanical stress, state standard, standard reference materials, method of calibration, measurement procedure.
