• Actual presence in the coatings of the substances declared using Gas chromatographic analysis (PTP CATAS)
• Effectiveness of biocidal products evaluated by inhibition test on agar. The test consists in exposing the coating to fungi cultures for an endurance test (PTP CATAS)
• Resistance to liquids at low temperature (UNI EN 12720)
• Test of wet adhesion (EN 927-8)
