General test method for tensile strength testing machines

General test method for tensile strength and elongation of footwear soles. MIsTextile Testing Instruments, Testing Equipment Manufacturer
Tensile strength: the tensile stress at the maximum force value. MIsTextile Testing Instruments, Testing Equipment Manufacturer
Elongation at break: The ratio of the increased length of the test length to the original length when the sample breaks. Stress at specified strain: The stress required for the test piece to reach the specified strain. MIsTextile Testing Instruments, Testing Equipment Manufacturer

1. Shoe pullerMIsTextile Testing Instruments, Testing Equipment Manufacturer
2. Dies and Cutters: Dies for dumbbell-shaped samples. The parallelism of the narrow part of the mold should not exceed 0.05 mm. MIsTextile Testing Instruments, Testing Equipment Manufacturer
3. The thickness gauge has a stable platform and the presser foot has a fixed weight load, which can exert a pressure of 10 kPa ± 3 kPa. The diameter of the thickness gauge round flat presser foot is 10.0mm ± 0.1mm. MIsTextile Testing Instruments, Testing Equipment Manufacturer
4. The scale of the thickness gauge is 0.01mmMIsTextile Testing Instruments, Testing Equipment Manufacturer

made of polymer Sole and elastic material, the thickness is 2.0mm ± 0.2mm --- foam microporous outsole, the thickness is 4.0mm ± 0.2mm. MIsTextile Testing Instruments, Testing Equipment Manufacturer
——— Leather Outsole: The thickness is the thickness of the outsole. MIsTextile Testing Instruments, Testing Equipment Manufacturer
3. The number of samples for each test is at least 3, and an appropriate plodder should be used to obtain uniform thickness. If possible, the original smooth skin of the sample should be preserved. MIsTextile Testing Instruments, Testing Equipment Manufacturer

Sample Marking: If using a non-contact star detector, draw two reference marks on the sample with a suitable scriber to mark the length of the sample and mark two reference marks d on the narrow part of the samplewhich are equidistant from the center of the sample and perpendicular to the axis of the sample, as shown in Figure 2. When marking, the sample should be in an unstressed state. MIsTextile Testing Instruments, Testing Equipment Manufacturer
