Dye spot test according to DIN EN ISO 2143

The dye spot test determines the quality of the sealing of anodisation layers. The anodised layer is first exposed to an acid treatment and then treated with a dye solution. The degree of (irreversible) staining is assessed by a characteristic value and serves to classify the sealing quality.
