BS ISO 22858:2020

This standard BS ISO 22858:2020 Corrosion of metals and alloys. Electrochemical measurements. Test method for monitoring atmospheric corrosion is classified in these ICS categories:

• 77.060 Corrosion of metals

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.
