Laminate class 33

Laminate class 33 is used for high passable premises (offices, lobbies, exhibition halls).

 

As it is known, each customer wants to purchase laminate with a high abrasion resistance index. Often this index is marked separately by manufacturers. Laminate is also tested according to this criterion. Laminate panels abrasion resistance is defined by means of Taber test. This test calculates a number of turns, made by a grinding wheel, equipped with abrasion paper. Turns are scored up until the first signs of abrasion appear. This index is called IP (initial phase). In accordance with newly accepted norms EN 13329, depending on quantity of turns, laminate is marked with a certain class.

Previously surface abrasion resistance was determined by other factors included into the norm EN 438. Nowadays, these factors, i.e. the number of turns, included into EN 438, are featured in ads of manufacturers. Do not misunderstand, criteria of EN 438 and EN 13329 are not opposed to each other. The fact is, according to the newly accepted norm, the process of measurement was changed. Abrasion paper in Taber test is replaced not after 500 wheel turns, as it was previously practiced, but after 200 turns. It means that the upper layer frays faster.

There are also utilization classes of laminate coverings. Here belongs 33 utilization class for business premises with an intense load and high passable premises (offices, lobbies, exhibition halls). Laminate floor endurance is 5- 6 years, and for a living space тАУ 15 -20 years, provided that it receives a proper care. Therefore, some manufacturers furnish a guarantee for the whole utilization period of this floor covering. One of the main advantages of laminate is its exterior, maintained for a long period of time, set for floor.
