Test Purpose:
The testing examined changes in colour and gloss occurring on copper surface due to the effect of solar radiation and moisture.
Test Method in Detail:
The colour and gloss of a Nordic Brown Light copper sheet was measured weekly. The sheet was aged by the use of combined daylight and moisture stress. Acidic (pH 5) sulfidic water was used for the moisture stress test of the sample. The total duration of the test was 1 000 hours. The dose of solar radiation was 1 224 kWh/m2. A product in Northern Europe will be subjected to a comparable dose of solar radiation during a time span of 16 months on average.
