Corrosion field-tests

Corrosion testing in field conditions is necessary in order to obtain real and relevant data on material life cycles and degradation in different environments.

In the case of atmospheric corrosion, testing involves exposing metal coupons or industrial products to real environments for a specific period of time and then evaluating the corrosion using standardised methods. Testing can be conducted at either a mobile station in a transport environment or a static field station. 

At Swerea we has a number of permanent field stations at our disposal, but also work in partnership with institutes with stations in marine, industrial and urban environments around the world. We have field stations in rural environments (Enköping/Ryda), urban environments (Stockholm), industrial environments (Singapore and China), as well as marine environments (Bohus-Malmön, Brest and Singapore).

The environment at our atmospheric field stations is used to measure a variety of environmental parameters, as well as determine corrosion rates for carbon steel, zinc, copper and aluminium in accordance with the standards ISO 8565 “Atmospheric corrosion testing – General requirements for field tests” and ISO 9226 “Corrosion of metals and alloys – Corrosivity of atmospheres”.
