25、inciple A metal ball with six rubber studs rolls freely inside a rotating drum that 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 t
26、hat 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. 5 Apparatus 5.1 Drum tester, conforming to 5.1.1 of ISO 10361:2000, including a vacuum cleaner with an air change rate at the nozzle of 25 l/s to 4

Before cutting,
32、 mark the corners of the tiles and the direction of manufacture on the back of the specimen as shown in Figure 3.

34、ure (see Figure 4). The cut shall cross at least one pile row. The cut shall be made with a sharp cutting tool (carpet knife or a press cutter), cutting from the pile side through the pile and backing. Connect the two sides of the cut specimens on the back with a single-sided adhesive tape of at lea
35、st 50 mm width. Apply the adhesive tape firmly. Ensure that the two edges are as close as possible. Attach double-sided adhesive tape along the entire specimen length and positioned over the single- sided tape. Cover both ends of the specimens with a 50 mm wide single-sided adhesive tape to prevent
36、fraying during the test. If necessary remove frayed and sprouting parts of damaged tufts with a sharp cutting tool. NOTE If the seams are sealed with seaming cement in practise then they can also be sealed with a seaming cement on the test specimens. Dimensions in millimetres 10 1 2020 Key 1 Cut Fig

Make up four composite test specimens
38、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 with the single-sided adhesive tape.

39、05 (E) 10 Attach double-sided adhesive tape along the entire specimen length and position over the single- sided tape. If necessary remove frayed and sprouting parts of damaged tufts with a sharp cutting tool. 7 Atmosphere for conditioning and testing Condition the specimens (face up) in the standar
40、d atmosphere for textiles, as defined in EN 20139, for at least 24 h. Conduct the test in this atmosphere. 8 Procedure Remove the protective layer from the double-sided adhesive tape on the back of the specimen. Fix the four specimens on the inside of the drum with the use-surface towards the centre
41、 of the drum. In placing the specimens, ensure that the sides lie within the retaining segments. Insert the specimens between the retaining segments and clamp firmly. Place the ball (5.2) in the drum. Set the revolution counter to 11 000 cycles and switch the machine on. Operate the vacuum continuou
42、sly throughout the test. After the test, clean the specimens with the external vacuum cleaner with rotating brush, making four passes in each direction along the length of the specimen, the last pass being in the direction of pile lay. 9 Assessment Place the specimen on the rotating observation tabl
43、e as defined in EN 1471 and use the observation conditions specified in EN 1471. Make sure the specimens lay perfectly flat, especially in the cut area. Check for degradation of the cut edges by the fatiguing action in the test. Note the type of damage as defined in Clause 3, in particular if fibres
44、 or yarns are pulled out on to the surface, and, if so, from which part of the floor covering they originate (pile or substrate). Check by close inspection under the observation conditions specified in EN 1471 whether there has been delamination, and, if so, the length and width of each delaminated
45、area. Check by close inspection under the observation conditions specified in EN 1471 the number of yarns pulled out with a length greater than one loop (loop pile products). The floor covering is considered to be resistant to fraying when none of the specimens show delamination with more than 30 mm
46、 length and more than 10 mm depth and not more than 1 out of 4 specimens shows an unacceptable degradation. Following damage is considered to be unacceptable: visible tuft out (tuft out of tufts or loops cut during specimen preparation is not to be taken into consideration when assessing tuft out);
