The aim of the test method is to provide an assessment of the corrosivity on carbon steel of combustion by-products from power and district heating plants before and after accelerated ageing at 40 °C in a measuring cell made for the purpose. The by-products are wetted by capillary action without forced wetting or sprinkling simulating rain.
The corrosion conditions are characterised by:
- Resistivity development due to capillary action.
- Corrosion potentials.
- The corrosion rate.
- Macro corrosion elements.
- Need for cathodic protection.
This method represents a realistic tool to estimate corrosion of carbon steel in fill consisting of modern by-products, where precipitation is drained off and other wash outs are avoided in order to reduce pollution of ground waters etc.
