Abstract
Objective: To assess the adequacy of linear function of calibration according to GOST R ISO 11095-2007 for ethanol mass concentration measurement using internal reference materials (RMs).
Material and methods: An experiment on calibration in accordance with the GOST R ISO 11095-2007 National standard of the RF was carried out using internal RMs, namely aqueous solutions of ethanol at different concentrations. Measurements were performed for two subbands of ethanol concentrations at RMs: 0.15-1.05 and 1.0-7.0 mg/ml - according to the certified methodology.
Results: The graphs of the calibration's functions based on experimental data are consistent with the assumption of the calibration function's linearity, as well as the assumption of the standard deviation's constance of residues is equitable for two subbands of RMs.
Conclusion: Proven linear models in the calibration experiment may be recommended for use in the ethanol mass concentration measurement.
[根据 GOST R ISO 11095-2007 标准对乙醇质量浓度测量校准线性函数的充分评估]。
目的评估根据 GOST R ISO 11095-2007 标准使用内部参考物质（RMs）测量乙醇质量浓度时校准线性函数的适当性：根据 GOST R ISO 11095-2007 RF 国家标准，使用内部参考物质（即不同浓度的乙醇水溶液）进行了校准实验。对两个子波段的乙醇浓度（RMs）进行了测量：结果：结果：根据实验数据绘制的校准函数图与校准函数线性假设一致，两个子波段 RM 的残留物标准偏差常数假设也一致：结论：校准实验中经过验证的线性模型可推荐用于乙醇质量浓度测量。
