Назначение стандартного образца:
– поверка, калибровка, установление и контроль стабильности градуировочных
(калибровочных) характеристик средств измерений, а также контроль метрологических
характеристик средств измерений при проведении их испытаний, в том числе, в целях
утверждения типа;
– аттестация методик (методов) измерений, контроль точности результатов измерений,
полученных по методикам (методам) в процессе их применения в соответствии с
установленными в них алгоритмами.
Стандартный образец представляет собой искусственную смесь, состоящую из определяемого компонента и органического разбавителя. Смесь находится в баллонах из алюминиевых сплавов АМг6, 1330 по ГОСТ 4784-2019 или нержавеющей стали 12Х18Н10Т, 03Х17Н14М2, 03Х17Н14М3 по ГОСТ 5632-2014 (в том числе, баллоны слайнером из нержавеющей стали) вместимостью (0,1 – 10) дм3 одногорловых, оборудованных двухпортовыми вентилями с устройствами сифонного типа, или двухгорловых; расфасованных виалах, бутылках или стеклянных запаянных ампулах вместимостью (0,001 – 1) дм3. Показатели пожаровзрывоопасности веществ и методы их определения указаны в ГОСТ 12.1.044-89, ГОСТ 31610.20-1-2020 (ISO/IEC 80079-20-1:2017).
