Abstract

Objective: Implementation of the control method to validate previously obtained calibration functions according to GOST R ISO 11095-2007 using Reference Materials (RM): standard RMs - aqueous solutions of ethanol, produced and certified by the organization, and internal RMs - aqueous solutions of ethanol in different concentrations, developed by the user for internal use.

Material and methods: We applied the control method in accordance with the National Standard of the Russian Federation GOST R ISO 11095-2007 using the standard and internal RMs - aqueous ethanol solutions in different concentrations. Measurements were performed for two subranges of ethanol concentrations on standard and internal RMs in accordance with the certified method.

Results and conclusion: Control charts based on experimental data confirmed that the system was in a controlled state, and the calibration function required no updates on Day 7. No studied values fell outside the upper and lower control limits on the control charts. The uncertainty of the transformed values was assessed during the calibration function validation.

目标：根据 GOST R ISO 11095-2007 使用标准物质（RM）实施控制方法以验证之前获得的校准函数：标准 RM - 由组织生产和认证的乙醇水溶液，以及内部 RM - 由用户开发供内部使用的不同浓度的乙醇水溶液：我们根据俄罗斯联邦国家标准 GOST R ISO 11095-2007 使用标准和内部 RM（不同浓度的乙醇水溶液）进行了控制方法。根据认证方法对标准和内部 RM 的两个乙醇浓度子范围进行了测量：基于实验数据的控制图证实系统处于受控状态，校准功能在第 7 天无需更新。没有研究值超出控制图上的控制上限和下限。在校准功能验证期间，对转换值的不确定性进行了评估。
