Application
The VIT 212 Wyzenbeek Abrasion Tester, with its modern ergonomic design, determines the abrasion resistance of fabrics when rubbed against a standard abrasive or a wire mesh screen using a back-and-forth motion over a curved surface. Commonly used in the automotive and furniture industries, this tester meets US standards and features motor-driven operation with 4 abrasion heads and an electronic digital counter to control the number of cycles.
Testing Method
Wyzenbeek Test Method: Double rubs measure a fabric’s resistance to abrasion, determined through the Wyzenbeek Test. A piece of stiff cotton cloth rubs back and forth over the sample fabric, replicating the friction of seating wear. Each backward and forward motion counts as one rub, with the test continuing until visible wear, two yarn breaks, or 15,000 double rubs is reached—considered too intense for domestic use.
Wyzenbeek vs. Martindale:
- Wyzenbeek (North America): Measures abrasion resistance with back-and-forth motion over a curved surface.
- Martindale (Europe/Asia): Uses a figure-eight motion over a flat surface, generally considered more accurate.
- Conversion Ratio: 4 Wyzenbeek cycles = 3 Martindale cycles
