标准范围

本文件规定了使用双电极电化学传感器进行大气腐蚀测量的试验方法。它适用于测量非耦合金属表面的腐蚀速率（即“自由”腐蚀速率）、电偶腐蚀速率、薄膜溶液的电导率和有机涂层的阻隔性能。它规定了使用或不使用有机涂层的电化学传感器。该传感器适用于在实验室试验室、户外暴露场所和服务环境中进行的腐蚀测量。

This document specifies a test method for atmospheric corrosion measurements, using two-electrode electrochemical sensors.It is applicable to measurements of the corrosion rate of uncoupled metal surfaces (i.e. "free" corrosion rate), galvanic corrosion rate, conductance of thin film solutions and barrier properties of organic coatings. It specifies electrochemical sensors that are used with or without organic coatings. The sensors are applicable to corrosion measurements made in laboratory test chambers, outdoor exposure sites and service environments.
