22、 of the initial distance 4 Apparatus and material The following apparatus and material shall be used: 4.1 Dual micrometer gauge, standing on a firm base and loaded with a dead mass such that the presser foot applied a pressure of 50 kPa 5 kPa 1) . The gauge has a presser foot which is flat, circular

23、 and 10,0 mm in diameter. The gauge has scale divisions of 0,01 mm. 4.2 Measuring device Vernier calipers or similar, capable of measuring to an accuracy of 0,1 mm. 4.3 Glass or flat bottomed container of an adequate size such that the test piece can be placed in the bottom. 4.4 Oven, for heating th

24、e test piece to 358C and thermostatically controlled so that the test piece is kept within 18C of the required temperature during the heating period. 4.5 Distilled water 5 Sampling and conditioning From the shoe insoles, cut insoles, or component as supplied into two square or rectangular test piece

25、s of (60 mm 20 mm)3 (60 mm 20 mm), one to determine swelling and size growth and the other to determine shrinking. According to the given dimensions, cut the test piece as big as the sample will allow. If the test pieces are taken from the shoes or cut component, sampling shall be done according to

26、prEN 13400:1998. condition the test pieces according to EN 12222, for a minimum of 24 h. 6 Test method 6.1 Swelling and increase in size On one of the conditioned test pieces trace parallel lines 5 mm in from each side. Label the corners of the square or rectangle formed A, B, C and D (see Figure 1)

27、. Trace diagonals AD and BC. Mark the centre E and the half way points of the diagonals AE, BE, CE and ED and label them F, G, H and I. Measure the distances between the points A-B, C-D, A-C and B-D with a measuring device. Measure the thickness at points E, F, G, H and I with the dial micrometer ga

28、uge. Submerge the test piece in distilled water for 6 hours. The test piece must be fully submerged in water being loaded with a small weight. Take the test piece out of the water and eliminate superficial drops of water. Measure the distances AB, CD, AC and BD again and the thickness at points E, F

29、, G, H and I.Page 4 EN 12800:2000 BSI 05-2000 6.2 Shrinkage On the other conditioned test piece mark parallel lines in the same way as in 6.1 (see Figure 1). Measure distances A-B, C-D, A-C and B-D. Leave the test piece in the drying oven (see 4.4) for 24 h. Then measure again the distances A-B, C-D

30、, A-C and B-D. 7 Expression of results 7.1 Swelling Calculate the average value of the five thicknesses e o . Calculate the average value of the five thicknesses after removing the test piece from the water e f . Swelling, H, is calculated as a percentage (%) from the equation: H = 3 100 e f 2 e o e

31、 o where e f is the thickness of test piece when wet. e o is the thickness of test piece when dry. Express the result to the nearest 0,5 %. 7.2 Increase in size Calculate the average value of the initial distances A-B and C-D measured in accordance with 6.1 and call it a 1 . In the same way find the

32、 average of the initial distances A-C and B-D and call it b 1 . In the same way calculate the averages of the same distances measured after taking the test pieces out of the water and call it a 2 for the distances A-B and C-D and b 2 for distances A-C and B-D. Calculate the increase in size, V, expr

33、essed as a percentage, from the equations: V a = 3 100 a 2 2 a 1 a 1 (Increase in size in direction a) V b = 3 100 b 2 2 b 1 b 1 (Increase in size in direction b) Express the result to the nearest 0,5 %. 7.3 Shrinkage Calculate the average of the distances A-B and C-D measured in accordance with 6.2

34、 and call it a o . In the same way find the average of the distances A-C and B-D and call it b o . Calculate the averages of the same distances measured after leaving the test piece for 24 h in the oven at 358C and call them a 24 and b 24 . Calculate the shrinkgage S, as a percentage, from the equat

35、ions: S a = 3 100 a o 2 a 24 a o and S b = 3 100 b o 2 b 24 b o Express the result to the nearest 0,5 %. The result will be the average of the two values. 8 Test report The test report shall include the following information: a) the results for swelling, increase in size and shrinkage expressed acco
