We believe that the traditional circle, triangle and square classification described in standard 13489 – wooden and parquet floors, multi-layer parquet elements – does not represent the evolution of the market and does not consider the physiological limit of plants; for this reason Tecnik Wood has decided to propose choices (AB, C and RR) all falling within the free classes.

The free class covers any classification the manufacturer wishes to offer; the proportions or limits of the characteristics must be specifically indicated in the accompanying documentation and declared in accordance with the standard table.

It should be remembered that the free class does not mean that the producer is “free” to produce with each supply what he likes or is most convenient for him, but rather it is a way to name choices freely but whose parameters must be detailed and must be constant over time .

It is important to remember that standard 13489 provides that, considering the inevitable differences in classification, 3% of the elements in a lot can be of other classes. Any additional elements of other classes are permitted as long as the overall impression of the floor is not disturbed.
