1.1 本规程涵盖了一个实验程序，可用于检查收集和呈现电化学阻抗数据的仪器和技术。如果遵循，本规程提供了一种标准材料、电解质和程序，用于收集开路或腐蚀电位下的电化学阻抗数据，该数据应再现其他人在不同时间和不同实验室确定的数据。这种做法可能不适合收集所有材料或所有环境中的阻抗信息。 1.2 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 标准程序、标准材料和标准地块的可用性应允许研究人员检查其实验室技术。这种做法应该导致文献中的电化学阻抗曲线可以很容易地进行比较。 5.2 用于获得参考图的标准铁素体430型不锈钢（UNS 430000）样品可供希望检查其设备的人员使用。合适的电阻器和电容器可以从电子设备供应室获得。 5.3 这种测试方法可能不适用于所有材料或所有环境中的电化学阻抗测量。

1.1 This practice covers an experimental procedure which can be used to check one's instrumentation and technique for collecting and presenting electrochemical impedance data. If followed, this practice provides a standard material, electrolyte, and procedure for collecting electrochemical impedance data at the open circuit or corrosion potential that should reproduce data determined by others at different times and in different laboratories. This practice may not be appropriate for collecting impedance information for all materials or in all environments. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The availability of a standard procedure, standard material, and standard plots should allow the investigator to check his laboratory technique. This practice should lead to electrochemical impedance curves in the literature which can be compared easily and with confidence. 5.2 Samples of a standard ferritic type 430 stainless steel (UNS 430000) used to obtain the reference plots are available for those who wish to check their equipment. Suitable resistors and capacitors can be obtained from electronics supply houses. 5.3 This test method may not be appropriate for electrochemical impedance measurements of all materials or in all environments.
