End Use examples of heavy-duty installations where upholstery fabrics rated at 30,000 double rubs should be appropriate are single shift corporate, hotel rooms/suites, conference rooms and dining area usage.
ACT acknowledges that there are extreme wear situations that may require higher levels of abrasion resistance. End use examples that may require higher than 30,000 double rubs include: 24 hour transportation terminals, 24 hour telemarketing, 24 hour healthcare emergency rooms, 24 hour casino gambling areas, and such public gathering places such as theaters, stadiums, lecture halls and fast food restaurants.
It is strongly suggested that double rubs exceeding 100,000 are not meaningful in providing additional value in use. Higher abrasion resistance does not necessarily indicate a significant extension of the service life of the fabric.
The Wyzenbeek and Martindale tests are the two methods commonly used to predict wear-ability. Actual performance is determined by many factors such as fiber content, weaves, finished, furniture design, maintenance, cleaning, and usage. Durability of an upholstery fabric is a complex interaction (combination) of a number of performance tests that, in addition to abrasion, includes seam slippage, pilling, tensile strength, and usage.
There is no correlation between the Wyzenbeek and Martindale test so it is not possible to estimate the number of cycles that would be achieved on one test if the results from the other test were known.
