ISO 16773-2:2016给出了优化EIS数据收集的指南，重点是高阻抗系统。完整涂层中的高阻抗指的是阻抗大于109Ω？cm2的系统。这并不排除在阻抗较低的系统上进行测量。对于未涂层样品，可在ISO/TR 16208中找到额外信息。 ISO 16773-2:2016涉及以下内容: -仪器设置:要求和坑落； -数据验证:检查测量范围和数据的准确性； -进行EIS测量:样本考虑和仪器参数； -实验结果:呈现EIS数据的不同方法。 这些指南旨在确保获得可用于研究样本性能的EIS数据。ISO 16773的本部分未给出数据解释指南。

ISO 16773-2:2016 gives guidelines for optimizing the collection of EIS data with focus on high-impedance 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. For uncoated samples extra information can be found in ISO/TR 16208. ISO 16773-2:2016 deals with the following: - instrumental set-up: requirements and pit-falls; - data validation: checking the measurement range and the accuracy of the data; - performing an EIS measurement: specimen considerations and instrumental parameters; - the experimental results: different methods of presenting EIS data. These guidelines are intended to ensure the acquisition of EIS data that can be used to study the performance of the specimen. This part of ISO 16773 does not give guidelines for the interpretation of the data.
