标准摘要
[中文适用范围]： 本国际标准规定了使用基于断流器（CI）技术、弛豫伏安法（RV）或直流瞬态（DCT）测量的方法对高阻抗涂层样品进行电化学测量的实验装置进行评估的程序。 它提供了有关优化从高阻抗系统收集 CI、RV 和 DCT 数据的具体定义和指导。 完整涂层中的高阻抗是指阻抗大于 109 Ω/cm2 的系统。 这并不排除在阻抗较低的系统上进行测量。 本国际标准特别涉及： ——仪器设置：要求和缺点； ——数据验证：检查测量范围和数据的准确性； ——执行 CI、RV、DCT 测量：样本注意事项和仪器参数； ——实验结果：呈现 CI、RV 和 DCT 数据的不同方法。 遵循建议应确保获取可用于研究样本性能的 CI、RV 和 DCT 数据。 本国际标准没有给出数据解释的指南。 [外文原描述]： 1 Scope This International Standard specifies the procedure for evaluation of the experimental set-up of electrochemical measurements on high-impedance coated samples using methods that are based on the current interrupter (CI) technique, relaxation voltammetry (RV) or DC transient (DCT) measurements. It provides specific definitions and guidance on optimizing the collection of CI, RV and DCT data from highimpedance systems. High impedance in the context of intact coatings refers to systems with an impedance greater than 109 Ω/cm2. This does not preclude measurements on systems with lower impedance. This International Standard deals in particular with: — instrumental set-up: requirements and shortcomings; — data validation: checking the measurement range and the accuracy of the data; — performing CI, RV, DCT measurements: specimen considerations and instrumental parameters; — the experimental results: different methods of presenting CI, RV and DCT data. Following the recommendations should ensure the acquisition of CI, RV and DCT data that can be used to study the performance of the specimen. This International Standard does not give guidelines for the interpretation of the data.
