Both Wyzenbeek and Martindale are abrasion tests, also referred to as rub tests. They are different tests which measure different properties, and success in one does not infer success in the other. Wyzenbeek involves rubbing along the warp and weft of the fabric whereas Martindale uses a figure-of-eight motion. This article gives summary information to assist interior designers in specifying the right levels of abrasion resistance for upholstery.

For a complete guide to the Martindale test including its history, full methodology, rub count classifications, what the test does not measure, and detailed specification guidance, see our comprehensive article: The Martindale Rub Test: A Complete Guide for Interior Designers and Specifiers.

Heavy Duty Usage

For heavy duty upholstery applications, specify a minimum of 30,000 double rubs to the Wyzenbeek method, or 40,000 cycles to the Martindale method.

End use examples where fabric rated at 30,000 Wyzenbeek double rubs is appropriate include single-shift corporate offices, hotel rooms and suites, conference rooms, and dining areas.

More demanding environments may require higher figures. End uses that may require above 30,000 double rubs include 24-hour transportation terminals, 24-hour healthcare emergency rooms, 24-hour casino areas, and high-traffic public gathering spaces such as theatres, stadiums, lecture halls, and fast food restaurants.

Rub counts above 100,000 do not generally provide meaningful additional value in use. Higher abrasion resistance does not necessarily indicate a significant extension of service life.

Test Methods

Wyzenbeek. A sample of the test fabric is pulled tight in a frame and held stationary. Individual specimens cut from the warp and weft directions are rubbed back and forth using an approved fabric as the abradant. The number of double rub cycles achieved before two yarn breaks occur, or noticeable wear is observed, is recorded as the fabric’s abrasion rating.

Martindale. Fabric samples are mounted flat and rubbed in a figure-of-eight motion using a piece of worsted wool cloth as the abradant. The number of cycles the fabric can endure before showing an objectionable change in appearance, such as yarn breaks, pilling, or holes, determines the abrasion rating. Results are recorded in multiples of 5,000 cycles.

Can You Infer One Result from the Other?

No. There is no reliable correlation between Wyzenbeek and Martindale results. It is not possible to estimate the number of cycles a fabric would achieve on one test from the results of the other.

For heavy duty usage, the two equivalent thresholds are 30,000 Wyzenbeek double rubs or 40,000 Martindale cycles. In that sense, for a given level of usage, the Martindale figure is approximately 33% higher than the Wyzenbeek figure. This is a directional guide for specifying purposes only. A fabric scoring 100,000 on one test cannot be assumed to score 133,333 on the other. The result could be higher or lower. The only way to know is to test to both standards independently.

Despite what appears on other websites, including those of well-known fabric houses, you cannot infer a Wyzenbeek score from a Martindale score or vice versa.
