EN 13572:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee CEN/TC 309 "Footwear", the secretariat ofwhich is held by AENOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by May 2002, and conflicting national standards shall be withdrawn at the latest byMay 2002.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.SIST EN 13572:2004



EN 13572:2001 (E)41 ScopeThis European 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 :Method A : Needle perforations. For determining the force required to pull a row of needles through an uppermaterial, in a direction perpendicular to the row.Method B : Stitched seams. For determining the breaking strength of stitched seams in shoe upper and liningmaterials. This method is applicable to seams cut from shoes or made up to simulate footwear constructions.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and, the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 12222, Footwear - Standard atmospheres for conditioning and testing of footwear and components forfootwear.EN 13400, Footwear - Sampling location, preparation and duration of conditioning of samples and test pieces.EN ISO 7500-1, Metallic materials - Verification of static uniaxial testing machines - Part 1: Tension/compressiontesting machines - Verification and calibration of the force-measuring system (ISO 7500-1:1999).3 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.3.1seam strengthbreaking strength of a stitched seam as determined under specified conditions using a tensile testing machine3.2uppermaterials forming the outer face of the footwear which is attached to the sole assembly and covers the upper dorsalsurface of the foot. In the case of boots this also includes the outer face of the material covering the leg. Only thematerials that are visible are included, no account should be made of underlying materials3.3complete upper assemblyfinished upper, fully seamed, joined or laminated as appropriate, comprising the centre material and any lining(s)together with all components such as interlinings, adhesives, membranes, foams or reinforcements, but excludingtoe puffs and stiffenersNOTEThe complete upper assembly can be flat, 2-dimensional or comprise lasted upper in the final footwear.4 Apparatus and materialThe following apparatus and material shall be used:SIST EN 13572:2004



EN 13572:2001 (E)54.1 Method A4.1.1Tensile testing machine with a jaw separation rate of 100 mm/min ± 10 mm/min, a force rangeappropriate to the specimen under test (this will usually be less than 500 N for footwear upper materials), capableof 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:4.1.2.1Two rectangular rigid plates each of minimum width 30 mm and maximum thickness 6 mm. Each ofthe two plates is drilled with seventeen holes of diameter 1,1 mm ± 0,1 mm. The holes shall be in a straight lineparallel to and approximately 5 mm from one end of the plate. The holes should be evenly spaced so that thecentres 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 distancebetween the end of the spacing plate and the centre line of the row of holes in the other plate can be adjusted andset 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 theexposed 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 ofthe tensile testing machine so that the rows of holes are perpendicular to the axis of the machine.Figure 1 — Schematic diagram of needle holding jig (see 4.1.2.3)SIST EN 13572:2004
