25、definitions For the purposes of this European Standard, the following term and definition apply. 3.1 abrasion resistance uppers, linings and insocks surface resistance shown by an upper, lining or insock test piece when rubbed with an abradant fabric in a Martindale machine 4 Apparatus and material
26、The following apparatus and material shall be used: 4.1 Abrasion machine, with one or more test stations each including the following: 4.1.1 Circular specimen carrier with a clamping ring which grips the test specimen around its edge leaving an exposed raised flat circular portion of area 645 mm2 5
27、mm2. 4.1.2 Horizontal abradant table of sufficient size to incorporate a square central test area of side 88 mm. Typically, the abradant tables are circular and of minimum diameter 125 mm. 4.1.3 Means of holding the exposed flat portion of the test specimen carrier (4.1.1) in contact with the abrada
28、nt table (4.1.2) whilst allowing the test specimen carrier to rotate freely in the plane of the abradant table. 4.1.4 Means of producing relative movement between the specimen carrier (4.1.1) and the abradant table (4.1.2) which forms a Lissajous figure occupying an area of 60 mm 1 mm 60 mm 1 mm (se
29、e Figure 1). Each Lissajous figure requires 16 eliptical motions (revolutions) of the test specimen carrier and the speed of operation of the tester shall be 5 rad/s 0,4 rad/s 1) . NOTE For a speed of operation of 5 rad/s 0,4 rad/s, the speed of rotation of outer hubs of tester is 48 rev/min 2 rev/m
30、in. 4.1.5 Means of maintaining a constant pressure of 12 kPa 0,2 kPa between the specimen carrier (4.1.1) and the abradant table (4.1.2). The corresponding mass of the test specimen carrier and associated fitments is 795 g 5 g. 1) 1 rad 0,16 rev. 4.1.6 The parallelism of the abradant table (4.1.2) a
31、nd the test specimen holder (4.1.1) shall be maintained within 0,05 mm throughout each Lissajous figure. A dial gauge fitted in place of the specimen carrier can be used to verify the parallelism of the abradant table. Figure 1 Lissajous figure 4.1.7 The circumferential parallelism between the test
32、specimen holder (4.1.1) and the abradant table shall be better than 0,05 mm. This can be verified by attempting to insert slip gauges of thickness less than 0,05 mm under the edges of the flat face of the test specimen carrier. 4.1.8 Means of counting the number of abrasion cycles completed in terms
33、 of revolutions 16 revolutions 2) (100 rad) per cycle. 4.2 Four pieces of crossbred worsted spun, plain woven fabric, to be used as the abradant in the test, each of size sufficient to be clamped over the abradant table (4.1.2). The fabric shall comply with the following specification: Characteristi
34、c Warp Weft Yarn linear density (R63 2) tex/2 (R74 2) tex/2 Threads per unit length (1,7 0,1)/mm (1,3 0,1)/mm Singles twist (540 20) tpmZ (500 20) tpmZ Twofold twist (450 20) tpmS (350 20) tpmS Fibre diameter (27,5 2) m (29 2) m Minimum mass per unit area 190 gm-2 The two faces of the abradant fabri
35、c do not necessarily have the same abrasive characteristics and when supplied it should be noted which face the supplier recommends for use, this is normally the slightly smoother face of the fabric. Stocks of the fabric shall be controlled to ensure that only this face is used in testing. 4.3 Abrad
36、ant paper. A technical standard of 36 grit is recommended. 2) 1 rad 0,16 rev. 4.4 Pressing mass of suitable dimensions to place over the entire surface of the abradant table to ensure that the abradant fabric is held flat whilst it is clamped in position. The mass shall apply a pressure of 2 kPa 0,2
37、 kPa. 4.5 Cutting device such as a press knife of a sufficient size to produce test specimens that will be held firmly in the specimen holders (4.1.1). The exact size of the device depends on the design of the clamping system of the test specimen carrier. 4.6 Four pieces of table felt, mass/unit are
38、a 575 gm-2 to 800 gm-2, and thickness 2 mm to 3,5 mm. Both sides of the felt may be used. The felt may be re-used until both sides are either discoloured, or the thickness has been reduced to less than 2 mm, but felt used in wet tests shall only be re-used in wet tests. 4.7 Polyurethane foam of thic
39、kness (3 1) mm, density (30 3) kgm-3 and indentation hardness 5,8 kPa 0,8 kPa determined in accordance with annex A, for testing materials with a mass per unit area of less than 500 gm-2. 4.8 Water jet. A rubber tube with one end restricted and the other attached to a cold water tap at mains pressur
40、e is suitable. 5 Sampling and conditioning 5.1 At least two test specimens of sufficient size to allow them to be fixed firmly within the test specimen carriers (see 4.1.1) are required for each of the dry and wet tests. 5.2 Cut test specimens from various positions on the sheet material avoiding ar
41、eas within 50 mm of any manufactured edges. NOTE Test specimens can be taken either from materials likely to be used for uppers or from made-up uppers or finished footwear. 5.3 If testing woven fabrics, ensure that no two test specimens have the same warp or weft threads. 5.4 Select test specimens o
42、f patterned fabric so that each part of the pattern is tested. This can mean that more than two test specimens are required for each of the dry and wet tests. NOTE It may be helpful to cut an extra sample of the test material to be used as a reference when comparing any damage or discolouration of t
43、he abraded test specimens. 6 Test method 6.1 Principle Four circular test specimens are rubbed against pieces of a standard abradant fabric or a standard abradant paper under a constant pressure, with two of the pieces of abradant dry and two wet. The relative movement between the abradant and speci
44、men is a complex cyclic pattern (a Lissajous figure) which produces rubbing in all directions. The test is stopped after a prescribed number of cycles and the damage to the specimen is assessed. 6.2 Procedure 6.2.1 Place the test specimens in a conditioned atmosphere as specified in EN 12222 for at
45、least 24 h prior to testing and carry out the test in this environment. Test specimens for wet tests need not be conditioned prior to test. 6.2.2 For the wet test, fully saturate the abradant cloth (see 4.2 and 4.3) and table felt (see 4.6) by directing the water jet (see 4.8) to and for over their
46、surfaces until full saturation can be seen by a uniform darkening in colour. Never spray the water jet onto materials, which are fixed to the Martindale instrument. 6.2.3 Place the test specimen in the test specimen carrier clamping rings (see 4.1.1), so that the surface of the test specimen to be a
47、braded is facing outwards. 6.2.4 If testing materials with a mass per unit area of less than 500 gm-2 then place a similar size piece of the polyurethane foam (see 4.7) in each of the test specimen carrier clamping rings (see 4.1.1) as a backing for the test specimen. 6.2.5 Clamp the test specimen i
48、n the carrier so that it is not baggy, creased or distorted in any way. 6.2.6 Place a piece of dry or wet table felt onto the abrading table depending on whether dry or wet test conditions are being used. 6.2.7 Place a corresponding dry or wet piece of the abradant cloth or abradant paper over each
49、piece of table felt with the test face uppermost. 6.2.8 Place the pressing weight (4.4) on top of the abradant cloth or abradant paper and clamp the abradant in position so that it is free of wrinkles. 6.2.9 Repeat the procedure in clauses 6.2.1 to 6.2.7 for any other test stations. 6.2.10 Fit the filled test specimen carrier into the abrasion machine so that the test specimen is resting on the abradant. 6.2.11
