Wyzenbeek Abrasion Tester TF212
Wyzenbeek Abrasion Tester，to determine the abrasion resistance of fabrics when rubbed against a standard abradent or a wire mesh screen with a backward and forward motion over a curved surface. Wyzenbeek Machine complies with ASTM D4157, etc. Please contact us for more information about Wyzenbeek methods.
Wyzenbeek Abrasion Tester, made of modern ergonomic design, is to determine the abrasion resistance of fabrics when rubbed against a standard abrasive or a wire mesh screen with a backward and forward motion over a curved surface. Wyzenbeek abrasion tester applies to automotive and furniture industry fabric manufacturers working to US Standards Motor driven with 4 abrasion heads and electronic digital counter to control the number of cycles.

Double rubs are a measure of how resistant fabric is to abrasive forces. The vast majority of fabrics list them, and they help to determine what fabric is most suitable for the specific purpose you require. Double rubs are determined by an automated test known as the Wyzenbeek Test (also referred to as the Wyzenbeek Method).
Wyzenbeek vs Martindale:
In North America, The Wyzenbeek Method is the standard measure of a fabric’s abrasive resistance. A piece of stiff cotton cloth is laid over a machine and rubbed all over a sample of the fabric. The rubbing from sitting on a seat cushion is what the test attempts to replicate. Each backward and forward motion makes up one rub. The test continues until the fabric shows visible wear, two yarn breaks or 15,000 double rubs, which is regarded as too intense for domestic purposes.
Europe and Asia majorly recognize the Martindale Method for fabric abrasion test. This method is generally regarded as more accurate than the Wyzenbeek. A sample of the fabric is laid out flat and stroked in an adapted figure-eight movement against a piece of smooth woolen cloth. What is counted is the number of cycles the fabric endures prior to displaying some sign of wear.
The American Society of Testing and Materials (ASTM) acknowledges and accepts these two abrasion test methods.
Martindale to Wyzenbeek Conversion:
The rating ratio of Martindale to Wyzenbeek ratio is 4:3, while their units are equal.
For instance: 20,000 Martindale = 15,000 Wyzenbeek = the industrial benchmark for heavy-duty domestic upholstery.
Q: What is Wyzenbeek test?
A: Double rubs are a measurement of a fabric’s abrasion resistance. They are listed with most fabrics and are helpful in determining which fabric is right for your particular application. Double rubs are found through a mechanized test called the Wyzenbeek Test (sometimes called the Wyzenbeek Method). According to wikipedia, in the US, the Wyzenbeek test is often used instead of the Martindale.
Q: Do you know Wyzenbeek rating chart?
A: There are two charts for your reference.
Double Rubs for Residential Applications
|Heavy Duty||15,000+ double rubs||Suitable for family rooms
|Medium Duty||9,000-15,000 double rubs||Versatile. Good for living or family rooms|
|Light Duty||3,000-9,000 double rubs||Usually better suited for formal or occasional use furniture
|Delicate Duty||Less than 3,000 double rubs||Recommended for more decorative use as in curtains, drapes or pillows|
Double Rubs for Commercial Applications
|Contract Upholstery Minimum||15,000 double rubs||considered the minimum for general contract, commercial upholstery projects
|Heavy Duty||15,000-30,000 double rubs||Suitable for single shift offices, conference rooms, hotel rooms and dining areas
|Extra-Heavy Duty||30,000+ double rubs||Recommended for constant use as in hospital waiting areas, airport terminals, fast food restaurants, theaters, and stadiums|
Q: What’s the difference between Martindale vs Wyzenbeek?
A: Martindale and Wyzenbeek are rub tests, which measure different properties of fabrics. Martindale is a test rubbing in figure 8, and Wyzenbeek rubbing along the warp and weft directions. Martindale is the preferred test in Europe; Wyzenbeek is preferred in the United States.
Q: Why is the price of TF212 Oscillatory / Wyzenbeek Abrasion Tester higher than other peers?
A: You can see the details of machine from the figure or the video, which is same as the SDL’s, even goes beyond some parts of the SDL’s. What’s more, we are sure that we are unique in manufacturing technique of this machine, and other suppliers will not possess this technique. Although they can manufacture it, they can only produce the machine with the same appearance but different internal structure.
