ACT Voluntary
Guideline for
Knit Fabrics

The surface wear of a fabric caused by rubbing and contact with another fabric.

Low Traffic / Private Spaces – Knit Upholstery Fabrics
ASTM D4157 (ACT approved #10 Cotton Duck)
15,000 double rubs Wyzenbeek method

ASTM D4966 (12 KPa pressure)
20,000 cycles Martindale method

ACT studies indicate that results of multiple abrasion tests performed on some fabric structures may vary significantly – as much as 60 percent or more.

Double rubs exceeding 100,000 are not meaningful in providing additional value in use and not predictive of significant extension of a fabric’s service life.

There is no correlation between Wyzenbeek and Martindale results.

For more information please refer to abrasion white papers on the ACT website.
