Full Description

ISO 22858:2020 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.
