Standards

In recent years the quality of laminate floor coverings has been assessed almost exclusively on the basis of the Taber values. However, this method of testing is far from adequate for quality assessment purposes because according to EN 438-2.6 it allows deviations of up to 40%. Furthermore, this test method assesses only the abrasion resistance of the laminate element surface using a rotating sand paper to grind away the overlay until the first sign of damage to the printed pattern sheet becomes apparent. The precision of the workmanship, the properties of the substrate or the balancer used - to mention only some of the decisive quality criteria - are not taken into account at all.

Nowadays grossly inflated Taber values can be achieved without any technical difficulties with the result that the Taber value has become, primarily a marketing tool but it should be realised, however that no essential quality improvement is achieved through these manipulations. Indeed, this situation has led to confusion and misrepresentation in the market. With the new EU Standard, regulations which do not permit any false interpretations will be established throughout Europe.

The new EU-Standard is so designed that it fits in with the already existing EN 685 which classifies floor coverings generally - like linoleum and plastic flooring - into service categories consistent with their durability. The various service categories are depicted by means of pictograms. Laminate floor coverings for application domestic (21-23) and commercial (31-33) areas are taken into account. This easy-to-understand system enables an easy comparison between products from different manufacturers, and at the same time ensures that the selected products are of the right durability for the intended end use.

Surya Click HDF Laminate Flooring has already reoriented to comply with the future standard. In other words, our products are already being finished in accordance with these requirements, are subjected to continuous monitoring, and are marked for identification purposes accordingly.

The Taber Test according to EN 438-2.6 has been considerably modified in the new EU-Norm for Laminate Flooring with regard to the following points:

  • The sandpaper is to be changed every 200 revolutions (previously every 500 revolutions). The abrasion counts will be enormously reduced as a result.
  • Abrasive paper Taber Type S-42 or equivalent is to be used.
  • Precise definition of the IP (Initial Point) by means of clearly arranged posters and the use of Tappi-Charts to determine the size of the abraded surface. The IP is reached immedi- ately damage over an area of at least 0.60 m2 is suffered by the printed design in two quadrants and over an area of max. 0.60 mm2 in a third quadrant.
  • The test is concluded with the reaching of the IP. Accordingly, the definitions FP (Final Point), and AT (Average Taber) are no longer of any significance.

Intensive analyses conducted by the expert team showed that measuring errors are reduced to 10% when this modified method is used. The European Norm imposes the following clas- sification requirements for the various service categories according to EN 685:
