本文件规定了一种电化学测量耐候钢合金锈层离子转移电阻的方法，以评估其抗腐蚀性能[3]。该方法使用电化学交流阻抗测量[4][5][6][7][8]以及谐波分析来确定离子转移电阻，并使用锈层厚度测量来表征保护锈层在使用环境下的腐蚀保护稳定性。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a method for the electrochemical measurement of ion transfer resistance of the rust layer formed on weathering steel alloys in order to assess their protective properties against corrosion thereafter[3]. This method uses an electrochemical AC impedance measurement[4][5][6][7][8], together with harmonic analysis, to identify the ion transfer resistance, and a rust thickness measurement to characterize the stability of the protective rust layer in terms of corrosion protection under used environments.All current amendments available at time of purchase are included with the purchase of this document.
