It certifies the performances of coating systems for the protection of wood in outdoor environments. The coating cycles are subjected to a specific programme of tests and evaluated in accordance with the relevant technical standards (EN 927). Additional verifications, such as the assessment of the effectiveness against biological aggression, the assessment of stacking and the permeability to light, make the product certification a comprehensive verification tool that covers all the main technical characteristics typically required for these products.
How it works. CATAS inspectors visit the company premises annually to inspect and take product samples. The samples collected are applied and then subjected to the required laboratory tests. The main test is natural aging lasting two years (PLUS recognition). The company is required to carry out two internal checks per year for each type of certified cycle, as provided for in the regulations, and to send the results to CATAS.
