Abrasion – Low Traffic

Abrasion – High Traffic

ACT Voluntary
Guideline for
Knit Fabrics

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

High Traffic / Public Spaces – Knit Upholstery Fabrics
ASTM D4157 (ACT approved #10 Cotton Duck)
30,000 double rubs Wyzenbeek method

ASTM D4966 (12 KPa pressure)
40,000 cycles Martindale method

Abrasion test results are not necessarily a reliable indicator of fabric lifespan. Comparative laboratory testing results on the same textiles frequently differ and testing methods do not necessarily correlate well with the variables encountered in actual use by the end-user. Licensees using the ACT performance certification marks and publishing test results exceeding the ACT high-traffic abrasion guideline are required to provide the following statement on their samples, digital media, marketing materials, social media posts, direct and third-party websites:

Abrasion test results exceeding ACT Performance Guidelines are not an indicator of product lifespan. Multiple factors affect fabric durability and appearance retention.

ACT studies indicate that results of multiple abrasion tests performed on some fabric structures may vary significantly – as much as 60 percent or more. There is no correlation between Wyzenbeek and Martindale results. For more information please refer to abrasion white papers in the LEARN section of this  website.
