一、概述1.测量依据JJG657-2006《呼出气体酒精含量探测器》检定规程。2.测量环境条件室内温度:(25±2)℃;湿度:≤80%RH;电源电压:(220±22)V。3.测量标准液态有机气体配气装置:配置乙醇标准气体浓度的不确定度U=2%,k=2。无水乙醇:纯度为99.8%,U=2%,k=2。微量进样器:规格为10μL,U=0.03μL,k=2。
I. Overview 1. Measurement based on JJG657-2006 “expired gas alcohol content detector” test procedures. 2. Measurement of environmental conditions Indoor temperature: (25 ± 2) ℃; Humidity: ≤ 80% RH; Power supply voltage: (220 ± 22) V. 3. Measurement standards Liquid organic gas distribution device: configure the concentration of ethanol standard gas uncertainty U = 2%, k = 2. Absolute ethanol: purity 99.8%, U = 2%, k = 2. Microinjector: Size 10μL, U = 0.03μL, k = 2.
