22、ons For the purposes of this European Standard, the following terms and definitions apply. 3.1 resistance to damage on lasting ability of a material to be stretched simultaneously in all directions (distended) without being damaged 3.2 upper materials forming the outer face of the footwear which is
23、attached to the sole assembly and covers 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 taken of underlying materials 3.3 complete upper assembly fin
24、ished upper, fully seamed, joined or laminated together 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 NOTE The complete upper assembly can be fl

26、ea of diameter 25,00 mm 0,5 mm. The design of the clamping system of the machine shall ensure that the test specimen does not slip during the test, and shall neither stretch nor compress the central area of the test specimen as it is clamped.

30、of a sufficient size to allow them to be clamped firmly on the test machine (see 4.1), so that they do not slip during the test. In the case of leather use prEN ISO 2418 to select the sampling position from the butt region of the skin or side. For non-leather materials cut 3 test specimens from a ra
31、nge 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 For test specimens from footwear uppers, they shall not be cut from any areas containing seams
32、 or perforations and any other design features which mean that the test specimen will not be of uniform thickness across its entire surface area. Furthermore, no test specimens shall be cut from areas of finished shoe uppers which are subjected to strains during lasting, especially the toe and backp
33、art areas. Test specimens shall be prepared from complete upper assemblies when the lining material is permanently attached to the upper material.

34、sible 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. 5.3 Place the test specimens in
35、 a conditioned environment as specified in EN 12222 for 24 h prior to test and carry out the test in this atmosphere. 6 Test method 6.1 Principle A circular test specimen is clamped round its edge and is gradually distended by forcing a small metal ball attached to a plunger through the test specime
36、n. At a certain distension, measured in terms of distance travelled by the plunger, either cracks appear in the surface of the material or a layer of the material sustains permanent physical damage; this distension is recorded as the first damage point. At a higher distension the material usually bu
37、rsts and this distension can also be recorded. Throughout the test the travel of, and force on the plunger is monitored so that if required a plot of force against distension can be produced. 6.2 Procedure 6.2.1 Ensure the test machine is set with the central plunger retracted to zero or minimum dis
38、tension. If it has a maximum force pointer turn it to zero. 6.2.2 Tightly clamp the test specimen into the test machine so that the ball ended plunger acts on the reverse side of the test specimen (i.e. when testing grain leathers, the ball ended plunger will press against the flesh side of the leat
39、her) and the test specimen is flat. 6.2.3 For some thick test specimens a very high clamping force may be necessary whereas with thin test specimens care is required to avoid cutting into the test specimen. 6.2.4 Force the plunger into the test specimen at a rate of 0,20 mm/s 0,05 mm/s. 6.2.5 Record
40、 the point of first damage as the plunger stretches the test specimen as follows: a) When testing leathers the first damage usually occurs in the finish or the surface of the grain. Hence during the test continually observe the surface of the test specimen, at the centre where the maximum distension
41、 is taking place. At the first sign of surface cracking, record the force on the plunger and the distension of the test specimen. However, if the grain is still intact, continue until grain crack occurs and record also the distension and force at this point. Patent leather is a special case because
42、often the grain of the leather cracks before the patent surface film. Particular care is therefore required when observing patent leather test specimens. Two indications of the grain cracking are a small shallow depression in the surface of the film above the crack and a momentary drop in the force
43、on the plunger. If the patent film cracks this shall also be regarded as a “grain crack” whether or not a crack in the grain is visible. b) When testing non-leather materials such as coated fabrics the first damage usually occurs within the material, with no visible damage at the surface. Hence duri
44、ng the test continually observe the force on the plunger as the test specimen is stretched. When damage occurs to a layer of the test specimen the force on the plunger either stops rising, or falls, however this may only be momentary. Record this value and the distension of the test specimen at this
45、 point. 6.2.6 If the bursting point is required then continue to observe the test specimen and record the distension and force when the spherical end first appears through the sample. 6.2.7 Retract the plunger and remove the test specimen.

If there are signs of slippage occurring during the test, for example evident by a blurring of clamping rings, or of tearing of the clamped edges; reject the
47、 results and repeat the procedure with a new test specimen. 6.2.9 Repeat the procedure for the remaining test specimens. 7 Expression of results Calculate the arithmetic mean of the results for the three test specimens, for distension and force at the: a) first damage point, as in 6.2.5; b) graincra
48、ck (for leathers) if this does not occur at the first damage point; c) bursting point, as in 6.2.6, if required; quoting distension to the nearest 0,1 mm, and force to the nearest 10 N. 8 Test report The test report shall include the following information: a) results expressed in accordance with cla
49、use 7; b) if testing finished footwear or uppers, a description of the style of shoe tested including commercial style codes; c) a description of the material, including a commercial reference, if known; d) a description of the test piece (upper or complete upper assembly); e) reference to the method of test; f) date of testing; g) any deviations from this test method.
