It certifies the performances of coating systems for interior use. Depending on whether certain performance requirements are met, the intended use to which the coating system can be applied is defined: kitchen furniture, bathroom furniture, living room furniture and bedrooms. The requirements make a further distinction between horizontal surfaces and vertical surfaces, on the assumption that the former ones are subject to greater stress than the latter.

How it works. CATAS inspectors annually visit the company's plant to make inspection and sampling. The samples collected are applied and then subjected to laboratory tests that refer to: 

- methods deriving from international (ISO), European (EN) and national (UNI) standards;
- internal procedures deriving from CATAS experience;
- mandatory safety requirements to ensure the end user's health.

The company is also required to carry out an annual internal control for each certified coating system and to send the results to CATAS.
