ISO 10833 pdf download.Textile floor coverings — Determination of resistance to damage at cut edges using the modified Vettermann drum test
1 Scope
This International Standard describes a 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.

3 Terms and definitions
For the purposes of this International Standard, the terms and definitions in ISO 2424 as well as the following apply. 3.1 delamination separation of the use-surface and/or foundation/primary substrate of a textile floor covering from the secondary substrate 3.2 fraying loss of pile or substrate material of a textile floor covering from a cut edge 3.3 tufting out loss of tufts from the use-surface of a textile floor covering 3.4 sprouting release and appearance during use of extra long tuft legs which were accidentally trapped within the pile of a textile floor covering during manufacture 3.5 laddering/shooting loss of consecutive loops of the same column from the use-surface of a textile floor covering
4 Principle
A steel ball with six rubber studs rolls freely inside a rotating drum which is lined with the textile floor covering 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 in accordance with ISO 9405.
5 Apparatus
5.1 Drum tester, conforming to 5.1 .1 of ISO 1 0361 :2000, including a vacuum cleaner with an air change rate at the nozzle of to . See Figure 1 . 5.2 Steel ball, fitted with six cylindrical rubber studs these being fitted so as to be equally spaced from each other on the surface of the ball. The mass of the ball without rubber studs shall be . The diameter of the ball shall be . See Figure 2. A standard 1 4 stud ball with eight studs removed is not acceptable because of the wear it causes to the drum segments. 5.3 Rubber studs, conforming to ISO 1 0361 that are replaced before each test. 5.4 External vacuum cleaner, upright type with rotating brush and beater bar. 5.5 Single-sided adhesive tape, of width . 5.6 Double-sided adhesive tape, of width .
6.2.2 Tiles
Prepare four test specimens of each floor covering as shown in Figure 3, two to test the original tile cut edges in the direction of manufacture (pieces A and B) and two in the transverse direction (pieces C and D). Make up four composite test specimens with the original cut edge in the centre. Position the edges in the centre of the specimen as close to each other as possible and fix in position using the single-sided adhesive tape. Attach double-sided adhesive tape along the entire specimen length and position over the single-sided tape.
