The Martindale method is the most widely used method for testing upholsteries for abrasion resistance. During testing the fabric is rubbed against a standard wool textile with a given weight-load applied. Running at intervals of 5.000 circular rubbing motions, the test continues until two threads are worn.

Minimum requirements
Private and low traffic public areas: 10.000 – 15.000 rubs
High traffic private and office spaces: 15.000 – 25.000 rubs
Public spaces and transportation: 25.000 – 45.000 rubs

Pilling is the term used to indicate whether small balls of fibres, known as pills, form on the surface of the fabric due to wear.  

It is evaluated on a scale from 5 (best) to 1 (worst).

Lightfastness relates to the ability of a textile to retain its colour under light. When testing for lightfastness, samples are exposed to artificial daylight for a specified period.

The evaluation scale ranges from 1 (worst) to 8 (best). An increase of one point corresponds to a doubling of the lightfastness, i.e. the same fading takes twice as long.

There are differing requirements concerning the flame-retardancy of textiles dependent on the area of application, country or even region. Our textiles pass the majority of international standards and are also tested for a selection of regional requirements.

The term for determining the resistance of the textile’s colour to rubbing off and staining other materials. A distinction is made between wet and dry rubbing. 

It is evaluated on a scale from 5 (best) to 1 (worst).

Airflow resistance influences the sound absorbing qualities of a textile. Typically, the denser the construction of the textile, the higher the value. 

Acoustic absorption is indicated as αw-value which approximately corresponds to the percentage of sound absorbed. For instance, an αw-value of 0,4 translates into 40% absorption of sound.  Acoustic absorption of a textile is measured in its flat and draped state.
