Test method to determine the susceptibility of textile floor coverings to mechanical damage at cut edges. It is applicable to all textile floor coverings both as sheet materials and as tiles.
- delamination: separation of the use-surface and/or foundation/primary substrate of a textile floor covering from the secondary substrate or foam backing
- fraying: loss of pile or substrate material of a textile floor covering from a cut edge
- tufting out: loss of tufts from the use-surface of a textile floor covering
- sprouting: release and appearance during use of extra long tuft legs that were accidentally trapped within the pile of a textile floor covering during manufacture
- laddering/shooting: loss of consecutive loops of the same column from the use-surface of a textile floor covering
A metal ball with six rubber studs rolls freely inside a rotating (Vetterman) drum that is lined with the textile floorcovering specimens.
On sheet materials, a cut is made along the length of the specimens at an acute angle such that the cut edges are stressed in the test. Tiles are put together so that the original edges of the tiles form the joint, which is stressed in the test.
After the test, the appearance of the fatigued cut edges is assessed.
