Abstract
Specifications for methods of measuring the concentration of hydrogen in solid samples are analyzed. Multiple discrepancies in the results of comparisons of modern standard samples from different manufacturers are found experimentally and the probable source of these discrepancies is the method used to heat and melt samples in a carrier gas flow for the measurements. It is concluded that this method is unsuitable for metrological support of measurements of the concentration of hydrogen in structural materials, since the metrological characteristics of these means of measurement do not meet the requirements for safe operation in the modern economy.
