25、m strength1 ScopeThis International Standard specifies two test methods for determining the seam strength of uppers, lining or insocks, irrespective of the material, in order to assess the suitability for the end use.These methods are as follows. Method A: Needle perforations. For determining the fo
26、rce required to pull a row of needles through an upper material, in a direction perpendicular to the row. Method B: Stitched seams. 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 foo
27、twear constructions.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

33、ollowing apparatus and material shall be used.4.1 Method A4.1.1 Tensile testing machine, with a jaw separation rate of (100 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
34、 greater than 2 % as specified by Class 2 in ISO 7500-1.4.1.2 Needle holding jig, see Figure 1, including the following.4.1.2.1 Two rectangular rigid plates, each of minimum width 30 mm and maximum thickness 6 mm. Each of the two plates is drilled with 17 holes of diameter (1,1 0,1) mm. The holes sh
35、all be in a straight line parallel to and approximately 5 mm from one end of the plate. The holes should be evenly spaced so that the centres of the two extreme holes are (26,5 0,5) mm apart.4.1.2.2 One spacing plate, of width similar to the drilled plates and of thickness (3,5 0,5) mm.4.1.2.3 Means
36、 of securing the spacing plate, to the surface of one of the drilled plates such that the distance between the end 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 0,1) mm and (6,0 0,2) mm. The combination will be referred to as the lowe
37、r plate.4.1.2.4 Means of securing the other drilled plate, which will be referred to as the upper plate, to the exposed 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
38、 to one of the jaws of the tensile testing machine so that the rows of holes are perpendicular to the axis of the machine.2 ISO 2016 All rights reservedBS EN ISO 17697:2016ISO 17697:2016(E)1234Key1 needle2 clamp3 drilled plate4 spacing plate5 drilled plate6 distance (see 4.1.2.3)Figure 1 Schematic d

43、ecimens with the dimensions specified in Figure 2. Three shall be cut with the base edge 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
44、 pieces from complete upper assemblies when the lining material is permanently attached 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
45、 test specimens contain the same warp or weft threads.For test specimens, cut from 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 ISO 17709 and three with the base edge perpendicular to t
46、he X-axis.It can be impossible to cut a test specimen of sufficient size from certain 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.5.1.3
