Проанализированы требования к метрологическим характеристикам тензометров, предъявляемые в отечественных и зарубежных стандартах. Определены основные способы нормирования метрологических характеристик, проведен их сравнительный анализ. Установлены преимущества и недостатки нормирования метрологических характеристик экстензометров, определенных в ISO 9513 Metallic materials – Calibration of extensometer systems used in uniaxial testing и ASTM E83 Standard practice for verification and classification of extensometer systems. Предложен единый подход к способу выражения допускаемых значений погрешности в единицах, принятых для измерений механической деформации, и представлен порядок передачи единицы деформации таким средствам измерений, как экстензометры, тензометры и измерительные преобразователи деформации. Предлагаемая поверочная схема для средств измерений деформации имеет значимость при установлении метрологической прослеживаемости средств измерений деформации, применяемых при одноосных испытаниях.</p><p>Работа сфокусирована на вопросах, которые необходимо учесть при создании единой системы метрологического обеспечения измерений деформации, в частности – о необходимости введения классификации средств измерений деформации, способах нормирования метрологических характеристик и методах передачи единицы от эталонов к измерителям деформации.</p></abstract><trans-abstract xml:lang="en"><p>The article considers the problem of the lack of traceability of mechanical deformation measurement results to state standards of measurement units and describes a study aimed at developing a verification schedule design. The requirements for metrological characteristics of strain gauges presented in domestic and foreign standards are analyzed. The main methods of standardization of metrological characteristics are defined; their comparative analysis is carried out. The advantages and disadvantages of standardization of metrological characteristics of extensometers defined in ISO 9513 and ASTM E83 are established. A unified approach to the method of expressing permissible error values in units adopted for measuring mechanical deformation is proposed, and the procedure for transferring the unit of deformation to such measuring instruments as extensometers, strain gauges and measuring transducers of deformation is presented. The proposed verification schedule for deformation measuring instruments is important in establishing the metrological traceability of deformation measuring instruments used in uniaxial tests.</p><p>The work is focused on issues that need to be taken into account when creating a unified system of metrological support for deformation measurements, in particular, the need to introduce a classification of deformation measuring instruments, methods for standardizing metrological characteristics, and methods for transferring units from standards to deformation measuring instruments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тензометры</kwd><kwd>экстензометры</kwd><kwd>измерение деформации</kwd><kwd>поверочная схема</kwd><kwd>испытания на растяжение</kwd><kwd>испытания на сжатие</kwd><kwd>одноосные испытания</kwd><kwd>начальная расчетная длина</kwd><kwd>базовая длина</kwd><kwd>ISO 9513</kwd><kwd>ASTM E83</kwd><kwd>машины испытательные</kwd></kwd-group><kwd-group xml:lang="en"><kwd>strain gauges</kwd><kwd>extensometers</kwd><kwd>strain measurement</kwd><kwd>verification schedule</kwd><kwd>tensile tests</kwd><kwd>compression tests</kwd><kwd>uniaxial tests</kwd><kwd>initial gauge length</kwd><kwd>reference length</kwd><kwd>ISO 9513</kwd><kwd>ASTM E83</kwd><kwd>testing machines</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Адамов А.
