Цель проведенного исследования – разработка стандартных образцов газов с аттестованным значением низшей объемной энергии сгорания, прослеживаемым к государственному первичному эталону. Исходные чистые газы-кандидаты – водород, метан, этан и пропан, а также целевая неопределенность значения низшей объемной энергии сгорания – 0,3 %, были выбраны на основе результатов анализа метрологических характеристик парка калориметрического оборудования. Аттестованное значение низшей объёмной энергии сгорания прослеживается к государственному первичному эталону единиц энергии сгорания, удельной энергии сгорания и объемной энергии сгорания ГЭТ 16. Аттестованное значение для выбранных газов и его неопределенность были оценены с применением эталонных калориметров-компараторов для сжигания высоко- и низкокалорийных газов «УСВГ» и «УСНГ» из состава ГЭТ 16. Результаты, полученные в ходе экспериментальных исследований и характеризации стандартных образцов, подтвердили заявленные показатели точности. Продолжение исследований позволит в перспективе разработать стандартные образцы газовых смесей-имитаторов природного, попутного и других газов, а также включить число Воббе в список аттестуемых характеристик.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes research on metrological assurance of such measuring instruments as gas calorimeters and Wobbe index analysers. The purpose of the performed research is development of reference materials for gases with certified value of net volume-basis calorific value traceable to Russian state primary standard. Input set of candidate gases is hydrogen, methane, ethane and propane, as well as the target uncertainty of lower volumetric combustion energy value equal to 0,3 % – both were selected basing on results of metrological characteristics analysis of calorimetric equipment. The certified value of lower volumetric combustion energy is traceable to the State Primary Standard of combustion energy, specific combustion energy and volumetric combustion energy units GET 16. The certified value of selected gases and the uncertainty of this value were estimated with usage of comparing calorimeters for the combustion of high- and low-calorie gases «USVG» and «USNG» included in GET 16. Results obtained during investigational study and reference materials characterisation confirmed the stated accuracy. The continuance in prospect may allow development of reference materials for gas imitating mixtures of natural and casing-head gases as well as include Wobbe index in the list of certified characteristics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>низшая объемная энергия сгорания</kwd><kwd>число Воббе</kwd><kwd>газовая калориметрия</kwd><kwd>теплофизические  свойства</kwd><kwd>стандартный образец</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lower volumetric combustion energy</kwd><kwd>Wobbe index</kwd><kwd>gas calorimetry</kwd><kwd>thermophysical properties</kwd><kwd>reference  material</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность сотрудникам лаборатории научных исследований в области газоаналитических измерений ФГУП «ВНИИМ  им.
