This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 200
16、6, and conflicting national standards shall be withdrawn at the latest by February 2006. This document supersedes EN 1814:1997.

EN 1814:2005 (E) 4 1 Scope This docume
18、nt specifies 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. 2 Normative references The following referenced documents are indispensable for the application of
19、 this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、he purposes of this European Standard, the following terms and definitions apply. 3.1 delamination separation of the use-surface and/or foundation/primary substrate of a textile floor covering from the secondary substrate or foam backing 3.2 fraying loss of pile or substrate material of a textile fl
22、oor 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 that were accidentally trapped within the pile of a textile floor covering during manufacture 3.5 laddering; shooting lo
23、ss of consecutive loops of the same column from the use-surface of a textile floor covering EN 1814:2005 (E) 5 4 Principle 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 lengt
24、h 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. 5 Apparatus 5.1 Drum tester, conf

27、diameter of the ball shall be 120 mm 0,2 mm. 5.3 Rubber studs, conforming to ISO 10361, which shall be replaced before each test. 5.4 External vacuum cleaner, upright type with rotating brush. 6 Sampling and preparation of specimens 6.1 Sampling 6.1.1 General Sampling shall be carried out in accorda
28、nce with ISO 1957. EN 1814:2005 (E) 7 6.1.2 Sheet materials Prepare four specimens approximately 570 mm long (in the direction of manufacture) and approximately 265 mm wide. The longitudinal edge of the specimens shall be parallel to the direction of manufacture. EN 1814:2005 (E) 8 6.1.3 Tiles Take
29、at least four tiles of dimensions 500 mm 500 mm or of lesser dimensions. Before cutting, mark the corners of the tiles and the direction of manufacture on the back of the specimen as shown in Figure 3. From the tiles cut a total of eight specimens of width approximately 132 mm, as shown in Figure 3.

T
31、he 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 least 50 mm width. Apply
32、 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 fraying during the tes
33、t. 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.

34、in specimens of sheet materials 6.2.2 Tiles Prepare four specimens of each floor covering as shown in Figure 3, two to test the 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 edg
35、e 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. EN 1814:2005 (E) 10 Attach double-sided adhesive tape along the entire specimen length and position over the single-sided tape. If necessary r
36、emove 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 standard atmosphere for textiles, as defined in EN 20139, for at least 24 h. Conduct the test in this atmosphere. 8 Procedure Remove the pro
37、tective 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 of the drum. In placing the specimens, ensure that the sides lie within the retaining segments. Insert the specimens between the ret
38、aining 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 continuously throughout the test. After the test, clean the specimens with the external vacuum cleaner with rotating brush, making four passes
39、 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 table as defined in EN 1471 and use the observation conditions specified in EN 1471. Make sure the specimens lay perfectly flat, especial
40、ly 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 or yarns are pulled out on to the surface, and, if so, from which part of the floor covering they originate (pile or substrate). Che
41、ck 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 area. Check by close inspection under the observation conditions specified in EN 1471 the number of yarns pulled out with a length gr
42、eater 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 length and more than 10 mm depth and not more than 1 out of 4 specimens shows an unacceptable degradation. Following damage is consi
43、dered 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); EN 1814:2005 (E) 11 loops pulled out with a length greater than one loop. 10 Test report The test report shall state: a) reference to
