Assess the quality of carpeting correctly

Carpets are available in many different designs. Also the qualities are different within the individual groups. How to judge the quality of carpets based on certain characteristics, you can read here.

Standards for carpets

For so-called textile floor coverings, numerous standards apply. The most important standard is the DIN EN 685, besides also different standards regarding durability, abrasion determinations and usage layer weight determination play a role.

All coverings that have the structure of a carpet and have a fibrous surface are considered in the standard as textile floor coverings - so it does not matter if it is a carpet or carpet tiles.

  • Usage class as quality feature

For textile floors as well as for laminate use classes apply.

A distinction is made between floor coverings in the private sector and those intended for the commercial sector. The use classes for the private sector are the 20er numbers, for the commercial sector 30er numbers apply.

If you buy carpet flooring for your home, you will encounter the following usage classes:

  • Service class 21: suitable for residential areas with low usage
  • Service class 22: suitable for residential areas with normal use
  • Service class 22+: suitable for residential areas with normal to intensive use
  • Service class 23: suitable for residential areas with predominantly intensive use

Even for coverings that are intended for commercial use, the numbers 1 - 3 are awarded analogously. If you are looking for a soil with higher resistance, you can also turn to commercial flooring. Class 33 is the highest usage class suitable for sales rooms, for example, class 32 is designed for use in conference rooms and offices.

Number of polnobs

Carpets that are tufted can also be divided into different quality levels based on the number of tufts per square meter.

Depending on how many needles are tufted at which intervals, and how big the stitch length is, this results in a different number of pile naps per square meter.

Needle distances to each other are usually specified in needles per inch. The stitch length, however, in number of stitches per 10 cm carpet.

Classification into classes after the Polnoppen

  • simple bouclé, has about 7,000 - 40,000 tufts per m², also known as Berber
  • upscale bouclé, has about 50,000 - 100,000 tufts per m², can also be designed as a simple suede
  • upscale velor (the pile loops are cut through) have about 250,000 tufts per square meter
  • Premium suede can contain up to 620,000 tufts per square meter

The higher the number of tufts per square meter, the higher quality (and more expensive) is the carpet.

Polfadengewicht

The weight of the pile on a square meter can be used as an analog quality feature. The more polnops, the more thread is processed on one square meter.

This also increases the tangible carpet weight - but this can also be falsified by heavy laminating layers (on the underside) seemingly increasing the weight of the carpet. Important is the weight of the pile thread, not the carpet itself.
