摘要：
Hydrogen is a key parameter that determines the safe operation of defense and civilian facilities. The maximum allowable level of hydrogen concentration in high-strength steels and aluminum alloys for aviation is 0.05-0.5 ppm. For technological control of the quality of materials and ensuring the principle of unity of measurement tools, state standard samples (SSS) are required, in which the certified values of the hydrogen content are in this range. The article presents data on the development and study of the stability of the certified value of the new generation of SSS. The production of these samples, together with the AV-1 precision mass spectrometric analyzer of hydrogen, completes the work of the team of authors to create a metrological quality control system for modern materials for the aerospace industry.
