This Standard is applicable to whole shoe in footwear.2 Normative ReferencesThe following documents are indispensable to the application of this document. In terms of references with a specified date, only versions with a specified date are applicable to this document. In terms of references without a specified date, the latest version (including all the modifications) is applicable to this document. GB/T 16825.1-2008 Verification of Static Uniaxial Testing Machines - Part 1: Tension/compression Testing Machines - Verification and Calibration of the Force- measuring System; GB/T 22049-2019 Footwear - Standard Atmospheres for Conditioning and Testing of Footwear and Components for Footwear3 PrincipleAdopt tension testing machine, which can continuously record tension, to determine the maximum tension value (namely, pull-out force of upper band) when pulling upper band out of shoe sole.4 Instruments and Equipment4.1 Tension Testing Machine 4.1.1 Comply with Grade-2 requirements in GB/T 16825.1-2008; measuring range: not less than 350 N; equipped with an indicating device, which can record the maximum tension value. 4.1.2 Fixture shall be constituted of upper fixture which clamps upper band, and lower fixture which clamps shoe sole. The width of the upper clamp clip shall be not less than of (25.0 ± 0.5) mm. Thoroughly cut the upper band, so as to guarantee that the sample strips are not connected with other parts of the upper band. Maintain the shoe sole in its original shape. From the middle, cut the upper band open. 5.2.3 If the width of the upper band is less than 25.0 mm, cutting will be unnecessary; directly cut open the upper band from the middle. 5.2.4 Use Vernier caliper to measure the width of the upper band where it connects with the bottom of the band. If the shoes are in shoelace-style structure, then, measure the diameter of the circular cross section of the upper band where it connects with the bottom of the band. 5.2.5 Respectively test the internal side and the external side of the upper band. In terms of flip-flops, the pull-out force of the upper band in the thong part shall also be tested. 5.3 Conditioning Before test, samples shall be placed for at least 4 h under the temperature condition of the reference standard environment in accordance with the stipulations in GB/T 22049-2019.6 Test Methods6.1 Test Conditions 6.1.1 The tensile speed of the tension test machine shall be: (100 ± 5) mm/min. 6.1.2 In accordance with the stipulations in GB/T 22049-2019, conduct the test under the temperature condition of the reference standard environment. 6.2 Test Procedures 6.2.1 Adjust the zero point of the tension test machine; set up the tensile speed. 6.2.2 Use the upper clamp on the tension test machine to clamp the upper band or the thong; use the lower clamp to clamp the shoe sole. The part that connects the bottom of the upper band cannot be clamped. 6.2.3 Adjust the location of the fixture. Conduct visual inspection to make the force- bearing direction of the upper band or the thong vertical to the shoe sole, and consistent with the force application direction of the tension test machine. 6.2.4 Initiate the tension test machine, till the upper band or the thong is separated from the shoe sole, or, till the material ruptures. Stop the machine; record the maximum tension value. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
