Compression and work of compression are calculated betwee

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
34、cycles (or Hexapod Tumbler Tester 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 suit

BS EN 14499:2015EN 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
40、at each end. One end 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 fibro
41、us construction. A.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 dim
42、ensions of (240 5) 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 edg
43、es where the folds 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 br
44、eaking. A.5 Test report Report the number of cracks or breaks and their length and location relative to the position of the metal plate during loading.

46、ion shall be determined in accordance with BS 4098 except that a pressure foot of between 700 mm2and 1 000 mm2is used and loading of the specimen is only up to 100 kPa. The work of compression may be calculated either directly by integration of the area under the loading curve between 2 kPa and 100
47、kPa by computer (Method 1) or by determination of the area from discrete thickness measurements (Method 2). If Method 2 is used, thickness measurements shall be taken at 2 kPa, 5 kPa, 10 kPa, 20 kPa, 50 kPa and 100 kPa pressure and the work of compression calculated in J/m2, using the following expr
48、ession: Wc= (1,5t2- 4t5+ 7,5t10+ 20t20+ 40t50 73t100) Where Wcis the work of compression in J/m2; tnis the thickness (in mm) at n kPa pressure.
