Description

Application

Wyzenbeek Abrasion Tester is a handy instrument for testing the Wyzenbeek abrasion resistance. In the testing, according to the Wyzenbeek abrasion test method, fix the sample fabrics on a standard abrasive or a wire mesh. Then it rubs on a curved surface in a forward and backward motion for a defined period of time. The Wyzenbeek abrasion tester is available for fabric manufacturers in the automotive and furniture industry.

Wyzenbeek abrasion tester consists of 4 abrasion heads and an electronic digital counter to control the number of cycles. Besides, it is in accordance with the standard ASTM D4157. If you are searching for information about ASTMD4157 pdf, you can click here.

The definition of Wyzenbeek

The double rub is a way to measure the abrasion resistance and durability of fabrics, one of which refers to back-and-forth motion. The vast majority of fabrics require double rub testing to facilitate the determination of which fabric is suitable for a specific application. Double rubs are determined by an automated test known as the Wyzenbeek Test, also named the Wyzenbeek Method.

Wyzenbeek vs Martindale

In North America, the Wyzenbeek Method is the standard measure of a fabric’s abrasive resistance. A stiff cotton cloth is laid over a machine and rubbed all over a fabric sample. 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 needs to stop when the fabric shows visible wear, two yarn breaks, or 15,000 double rubs, which is regarded as overintense for domestic purposes.

The Martindale Method for fabric abrasion tests is widely available in Europe and Asia. It is well-known that this method is more accurate than the Wyzenbeek. Laying the fabric sample flat then stroke in an adapted figure-eight movement against a piece of smooth woolen cloth. Finally, count the number of cycles the fabric endures before revealing some signs of wear.

The American Society of Testing and Materials (ASTM) acknowledges and accepts these two abrasion test methods.

Conversion to process Martindale into Wyzenbeek

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.
