Laminate floors are made up of:.

• Water-repellent high-density HDF wood fiber board, depending on the manufacturer the board may be more resistant than another. Some manufacturers do not use HDF in their board but rather MDF, medium density board.

• Decorative paper, is paper that imitates wood or the desired color.

• Melamine layer, depending on the manufacturer this may be more or less resistant. An AC-4 resistance melamine from manufacturer A is not as resistant as a melamine from manufacturer B.

• Anti-sway, some manufacturers use an anti-sway paper to prevent twisting on the board.

Because synthetic laminate can have very different properties depending on the manufacturer, floors are classified into five qualities according to the EN 13329 standard.[1]​

These categories are the result of an abrasion test, where a machine subjects the floor to a series of rubs with a wheel of sandpaper, until the decorative pattern loses its original appearance, that is, the test is carried out until the decorative pattern disappears (turns white). Example: If we use an AC4 or AC5 from a manufacturer A and do an abrasion test, it may turn white sooner than an AC4 or AC5 from a manufacturer B. It is not recommended to take the AC test into consideration as the only factor for choosing a laminate floor.

Depending on the number of turns supported, the resistance of the melamine or wear layer is:

Currently, laminated or synthetic floors are classified by use classes, not by AC resistance as this causes confusion. The current classifications have no similarity with the previous ones, since they do not follow a resistance-use criterion. A manufacturer may mark AC 4 with a class 31 and that is incorrect. What we do have to see in the material's technical sheet is the AC resistance associated with the class of use, so that there is coherence and agreement, but it is not conditional (the AC) to know if one material is more resistant than another, since more factors influence it, hence the majority of manufacturers only mark the packages with the classes of use. Example: An AC 4 from a manufacturer A has nothing to do with an AC4 from a manufacturer B. Today there are manufacturers that classify with AC5 and their use class is lower than Class 32, which is why they confuse the end customer..

The current classifications used for floating laminate flooring aimed at commercial prospects are:

The general classifications have a domestic and commercial range, which is why in the packages and technical sheets of laminate flooring we can see classifications of the type:.

23/31 which represents intense domestic and light commercial use, if we see 23/32 it means intense domestic and general commercial use. A 23/33 use class implies that laminate flooring is intended for heavy-duty residential and heavy-duty commercial applications. When we talk about index use classes 21, 22 and 23 they refer to applications in homes, however classes 31, 32, 33 and 34 refer to the commercial context; Extending the regulations, use classes starting at 41 are used within the framework of flooring for industrial use.
