Benefits of Eurodes

  1. To provide European reference points on the "EURODES ® Belt" for evaluating the behaviour of materials both from members, and non-members of the ECCA.

  2. To use a standard preparation and exposure method (EN 13523-19), and a standard method for the evaluation of panel corrosion and test results (EN 13523-21). See also EN 13523, parts 19 & 21.

  3. To enable member and non-member organisations to test large numbers of panels at European sites with specific recorded climatic conditions.

A fully integrated programme containing:

  • Setting up test and evaluation methods
  • Choice and approval of exposure sites
  • Preparation and exposure of samples
  • Inspection and evaluation reporting
  • EURODES ® - environmental measurements
  • Data recorded on EURODES ® sites includes (if relevant):
    • Average temperature
    • Rainfall in mm/year
    • Rainfall in hrs/year
    • Total global radiation
    • Average relative humidity
    • Time of wetness
    • Chlorides present in atmosphere
    • Air pollution
      • sulphur dioxide
      • ozone
      • nitrogen oxides
      • etc.
    • Weight loss, to control corrosivity of sites
    • pH measurement of collected rainwater

Eurodes standard tests


Under the EURODES ® programme, exposed panels can be evaluated and inspected visually and instrumentally. EN 13523-21 standard measurement includes:

  • Corrosion effects
  • Gloss and colour changes
