Domestic use rank
Parquet is classified according to the use classes defined below. The UPEC classification does not apply to parquet insofar as it can be renovated. The classification takes into account 4 criteria: Wear, Punching, Water and Chemistry. However, equivalences between the class of use and the UPEC classification are possible.
