State system for ensuring the uniformity of measurements. Gas generators vapor ethanol in the air. Verification procedure
Государственная система обеспечения единства измерений. Генераторы газовых смесей паров этанола в воздухе. Методика поверки
Status: Effective - Introduced for the first time. IUS 2-2017
The standard applies to the headsets of electric drives for arrows without external locking devices, headsets of electric drives with external locking devices for arrows and crosses with moving elements, external locking devices for arrows and crosses with moving elements intended for operation on public and non-public railway tracks. The standard is used in the development, design, manufacture and testing of headsets and external contactors in order to assess their compliance with safety requirements.
Стандарт распространяется на генераторы газовых смесей паров этанола в воздухе (далее-генераторы)-рабочие эталоны 1 и 2 разряда по ГОСТ 8.578, предназначенные для приготовления газовых смесей, используемых при проведении поверки и испытаний анализаторов паров этанола в выдыхаемом воздухе, в том числе в целях утверждения типа средств измерений, и устанавливает методику их первичной и периодической поверок. Настоящий стандарт распространяется на генераторы, основанные на методе барботирования воздуха через водный раствор этанола, термостатированный при номинальной температуре 34 °С и имеющие следующие метрологические характеристики:-диапазон воспроизведения массовой концентрации этанола в газовых смесях: нижняя граница, мг/м3 от 40 до 100; верхняя граница, мг/м3 от 1000 до 2000;-пределы допускаемой погрешности воспроизведения массовой концентрации этанола в газовых смесях (в зависимости от того, что больше): абсолютной, мг/м3 ± 4 или более; относительной, % ± 2,5 или более. Интервал между поверками генераторов устанавливают при утверждении типа средств измерений (далее-СИ) и указывают в свидетельстве об утверждении типа СИ. При проведении испытаний в целях утверждения типа СИ допускается разрабатывать методики поверки, распространяющие на конкретный тип генераторов, не противоречащие настоящему стандарту
