18、4EN 14159:2014 (E) 4 Introduction Owing to influences of the production process on the structure, textile floor coverings may show variations in size and distortion. However, in many cases, certain discrepancies can be eliminated by professional and careful installation. By open communication betwee
19、n manufacturer and installer, an agreement can be found between what is technically possible in manufacturing, and at the same time technically workable during installation. The maximum distortions in pattern repeat specified in this European Standard are applicable only to carpets with certain desi
20、gn styles ex-factory. BS EN 14159:2014EN 14159:2014 (E) 5 1 Scope This European Standard specifies the maximum accepted tolerances on the dimensions and distortions in pattern, of rugs, runners, carpet tiles and wall-to-wall carpet. NOTE These tolerances do not affect the functional characteristics
21、of the textile floor covering. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

28、ble of describing a datum line across the width of the carpet at 90 to the edge of the carpet. 5 Procedure 5.1 Measurement of dimensions Lay the rug or carpet roll out flat, use surface uppermost. Use the length measuring device (4.1) and the dividers (4.2), if appropriate, to measure the length (Ix
29、) and the width, (ly), in accordance with ISO 3018. 5.2 Measurement of pattern distortion 5.2.1 General Each of the following measurements can be made either on the face (tufted carpet) or back (woven carpet) of the unrolled carpet. 5.2.2 Distortion in pattern repeat Measure the distortion in patter
30、n repeat length as the distance between a line drawn across the carpet at the maximum extent of the pattern (l1), and an equivalent line drawn across the carpet at the minimum extent of the corresponding pattern (l2). Figure 1 shows an example of measurement of the distortion in pattern repeat lengt
31、h. Measure the maximum deviation to the appropriate accuracy (see 4.1) over n pattern repeats and over a length of at least 1 m. BS EN 14159:2014EN 14159:2014 (E) 7 The distortion (mm) is given by (l2- l1). The measurements should be repeated in a number of positions throughout the carpet and all re
32、sults quoted. Figure 1 Pattern repeat 5.2.3 Bowing Use the device described in 4.3 to draw a line perpendicular to the machine direction edge of the carpet. The line should be drawn perpendicular to the edge at a convenient reference point, i.e. one particular part of the pattern repeat that can be
33、traced across the width of the carpet. Use the length measuring device (4.1) and dividers (4.2) to measure the maximum deflection (aq) to the appropriate accuracy (see 4.1), as shown in Figure 2. The measurements should be repeated in a number of positions throughout the carpet and all results quote

Measure the maximum deflection (a) of the patter
35、n to the appropriate accuracy (see 4.1), as shown in Figure 3. The measurements should be repeated in a number of positions throughout the carpet and all results quoted. Figure 3 Linear pattern distortion BS EN 14159:2014EN 14159:2014 (E) 9 5.2.5 Skewing of pattern Use the device described in 4.3 to
36、 draw a line perpendicular to the production direction from a specific point on the pattern at one machine edge of the carpet to the opposite machine edge of the carpet. Use the length measuring device to measure the pattern deviation (ad) to the appropriate accuracy (see 4.1), as shown in Figure 4.
37、 The measurements should be repeated in a number of positions throughout the carpet and all results quoted. Figure 4 Skewing 5.2.6 Arcing Draw a perpendicular to one of the cross machine directions of the carpet and continue for the full length of the carpet. Draw a line to continue to the opposite
38、cross machine width until it dissects the perpendicular. Measure the maximum deviation (awo) as shown in Figure 5, to the nearest 1,0 mm.
