35、e effect dISO 10361 aThe requirement in EN ISO 13934-1 to include at least 20 threads in the test specimen need not be met. bThickness is measured in accordance with ISO 1765 at 10 equally spaced intervals across the full width of the underlay, using a presser foot area between 700 mm2and 1 000 mm2.

36、 cCompression and work of compression are determined in accordance with BS 4098 with following modifications: a presser foot of between 700 mm2and 1 000 mm2is used and loading of the specimen is only up to 100 kPa. Compression and work of compression are calculated between 2 kPa and 100 kPa (see Ann

37、ex B) before and after dynamic loading for 1 000 cycles in accordance with ISO 2094. Certain carpet thickness gauges may require modification and the manufacturers advice should be sought. dA carpet is tested, with and without the underlay in a Vettermann Drum for 22 000 cycles (or Hexapod Tumbler T

38、ester for 12 000 cycles) according to ISO 10361 and subsequently assessed according to EN 1471. There should not be a negative effect of the specimen tested over underlay compared to the specimen without underlay. 6 Classification All underlays shall be classified as suitable for different intended

39、use/applications in accordance with the performance levels shown in Figure 1 for work of compression after dynamic loading versus compression after dynamic loading. The designations and the descriptions of intended use/application are described in Table 2. Underlays should initially be specified for

40、 that particular application.

DIN EN 14499:2015-06 EN 14499:2015 (E) 8 Annex A (normative) Method for determination of resistance to breaking and cracking A.1 Principle A rectangular piece of underlay is folded at each end. One e

44、nd is placed under a weight-piece, whilst the other is folded without an added weight. After 1 h, the weight-piece is removed and each fold of the test specimen is visually assessed for signs of cracking. This test is applicable to all types of underlay except those of wholly fibrous construction. A

45、.2 Apparatus Rectangular rigid metal plate of dimensions (80 1) mm x (40 1) mm; Weight-piece, such that the combined mass of the rigid metal plate and the weight piece is (2,5 0,1) kg; Single-sided adhesive carpet tape, 50 mm wide. A.3 Test specimen The test specimen shall have dimensions of (240 5)

46、 mm x (120 5) mm. A.4 Procedure Fold the test specimen as shown in Figure A.1, so that, when folded, the edges of the test specimen meet and the backing material, if any, is innermost. Tape the edges of the test specimen together and then turn the test specimen over so that the edges where the folds

47、 meet are on the underside. Place the metal plate on the folded test specimen as shown in Figure A.2. Place the weight-piece on top of the metal plate and leave for 1 h. Remove the weight-piece and metal plate and immediately examine the folded specimen for signs of cracking and breaking. A.5 Test r

48、eport Report the number of cracks or breaks and their length and location relative to the position of the metal plate during loading.
