19、ng or insocks, irrespective of the material, in order to assess the suitability for the end use. These methods are : Method A : Needle perforations. For determining the force required to pull a row of needles through an upper material, in a direction perpendicular to the row. Method B : Stitched sea
20、ms. For determining the breaking strength of stitched seams in shoe upper and lining materials. This method is applicable to seams cut from shoes or made up to simulate footwear constructions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from o
21、ther publications. These normative references are cited at the appropriate places in the text and, the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment
22、 or revision. For undated references the latest edition of the publication referred to applies (including amendments).

24、 European Standard, the following terms and definitions apply. 3.1 seam strength breaking strength of a stitched seam as determined under specified conditions using a tensile testing machine 3.2 upper materials forming the outer face of the footwear which is attached to the sole assembly and covers
25、the upper dorsal surface of the foot. In the case of boots this also includes the outer face of the material covering the leg. Only the materials that are visible are included, no account should be made of underlying materials 3.3 complete upper assembly finished upper, fully seamed, joined or lamin
26、ated as appropriate, comprising the centre material and any lining(s) together with all components such as interlinings, adhesives, membranes, foams or reinforcements, but excluding toe puffs and stiffeners NOTEThe complete upper assembly can be flat, 2-dimensional or comprise lasted upper in the fi

28、 10 mm/min, a force range appropriate to the specimen under test (this will usually be less than 500 N for footwear upper materials), capable of measuring forces to an accuracy greater than 2 % as specified by Class 2 in EN ISO 7500-1. 4.1.2Needle holding jig, see Figure 1, including the following:
29、4.1.2.1Two rectangular rigid plates each of minimum width 30 mm and maximum thickness 6 mm. Each of the two plates is drilled with seventeen holes of diameter 1,1 mm 0,1 mm. The holes shall be in a straight line parallel to and approximately 5 mm from one end of the plate. The holes should be evenly
30、 spaced so that the centres of the two extreme holes are 26,5 mm 0,5 mm apart. 4.1.2.2One spacing plate of width similar to the drilled plates and of thickness 3,5 m 0,5 mm. 4.1.2.3Means of securing the spacing plate to the surface of one of the drilled plates such that the distance between the end
31、of the spacing plate and the centre line of the row of holes in the other plate can be adjusted and set at 3,0 mm 0,1 mm and 6,0 mm 0,2 mm. The combination will be referred to as the lower plate. 4.1.2.4Means of securing the other drilled plate, which will be referred to as the upper plate, to the e
32、xposed surface of the spacing plate so that the holes in both of the drilled plates are aligned. The end of one of the plates furthest from the row of holes should have means of attachment to one of the jaws of the tensile testing machine so that the rows of holes are perpendicular to the axis of th
33、e machine.

34、een needles, round point, 16 x 1, metric size 90. 4.1.4Press knife or other cutting device capable of cutting a T shaped test specimen of the dimensions shown in Figure 2. 4.2 Method B 4.2.1Tensile testing machine with, a jaw separation rate of 100 mm/min 10 mm/min, a force range appropriate to the
35、specimen under test (this will usually be up to 2 kN), capable of measuring forces to an accuracy greater than 2 % as specified by class 2 in EN ISO 7500-1. 4.2.2Small sharp hand knife or scissors for cutting test specimens. 4.2.3If made up seams are to be tested, a press knife capable of cutting te
36、st specimens, (50 mm 2 mm) x (50 mm 2 mm), is useful. 4.2.4If made up seams are to be tested, a sewing machine and accessories. 5 Sampling and conditioning 5.1 Method A 5.1.1Store the shoes or the uncut sheet material or uppers in a controlled standard atmosphere specified in EN 12222 for a minimum
37、of 24 h prior to testing and carry out the test in this atmosphere. Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 12:44:19 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13572:2001 (E) 7 5.1.2Cut six test specimens with the dimensions specified in Figure 2. Three shall be cut with the base e
38、dge of the T parallel to the along direction of the material (backbone direction for leather and selvage (warp) or machine direction for non-leather materials), and three shall be cut perpendicular to this. Prepare test pieces from complete upper assemblies when the lining material is permanently at
39、tached to the upper material. For materials cut test specimens from a range of positions across the full usable width and length of the sheet material. For a material with a woven structure this will ensure that no two test specimens contain the same warp or weft threads. For test specimens cut from
40、 footwear uppers avoid any areas containing perforations, cut three test specimens with the base edge of the T parallel to the X axis of the upper as defined in EN 13400 and three with the base edge perpendicular to the X axis. It can be impossible to cut a test specimen of sufficient size from cert
41、ain types of footwear especially childrens and the test specimen size shall not be reduced. If it is not possible to cut the correct size test specimen from a shoe upper the materials themselves shall be tested. 5.1.3Mark the along direction on each of the test specimens. 5.2 Method B 5.2.1Store the
42、 shoes or the uncut sheet material or uppers in a controlled standard atmosphere specified in EN 12222 for a minimum of 48 h prior to testing and carry out the test in this atmosphere. 5.2.2Test specimens cut from shoes or uppers: 5.2.2.1Where possible use the knife (see 4.2.2) to cut two rectangula
43、r test specimens of dimensions (90 10) mm x (50 2) mm from the upper, including any lining materials, such that the seam is approximately mid-way between the two ends of the test specimen, see Figure 3.

44、:19 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13572:2001 (E) 8 5.2.2.2If the shoe upper is too small to allow this, then the size of test specimen may be reduced but the width of the central portion, see 5.2.2.3 and Figure 3, shall not be less than 10 mm. 5.2.2.3Make cuts in each test specimen p
45、arallel to the longer edges from points 3 mm from the seam to the edges of the material, to provide a test specimen having a central portion of width 25 mm 0,5 mm and two edge pieces of width 12,5 mm 0,5 mm, see Figure 3. 5.2.3Test specimens prepared by making up seams: 5.2.3.1Use either the hand kn
46、ife or scissors (see 4.2.2) or press knife (see 4.2.3) to cut pieces, (50 mm 2 mm) x (50 mm 2 mm), of each material to be used in the construction. The number of pieces of material required will vary according to the construction of the seam. This may consist of two pieces of the same or different u
47、pper materials stitched together and may include one or more lining materials. Reinforcing tapes may also be included. Cut sufficient pieces to allow the preparation of three seamed test specimens for each direction of test. If required materials may be skived before seaming. The test direction, alo
48、ng or across, is at 90? to the direction of the seam. The number of directions of test will vary according to the upper construction. Separate tests in the along and across directions can be sufficient but in some cases test specimens can need to be prepared with along and across directions combined
49、 or with material cut on the bias. For non-leather materials cut test specimens from a range of positions across the full usable width and length of the sheet material. For a material with a woven structure this shall prevent any two test specimens containing the same warp or weft threads. 5.2.3.2Use the sewing machine (see 4.2.4) to stitch together the squares of material to produce three test seams for each direction of test. The choice of type of seam, needle size and type, thread and stitch density shall be selected to simulate th
