General test method for tensile strength and elongation of footwear soles.
u4VTextile Testing Instruments, Testing Equipment Manufacturer Tensile strength: the tensile stress at the maximum force value.
u4VTextile 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.

u4VTextile Testing Instruments, Testing Equipment Manufacturer 1. The movement speed is stable at 100mmmin, theprecision is level 2 and the force value is recorded automatically. Sample preparation:
u4VTextile Testing Instruments, Testing Equipment Manufacturer 2. The thickness of the sample is:
u4VTextile Testing Instruments, Testing Equipment Manufacturer ————high density
u4VTextile 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.
u4VTextile Testing Instruments, Testing Equipment Manufacturer ——— Leather Outsole: The thickness is the thickness of the outsole.
u4VTextile 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.
u4VTextile Testing Instruments, Testing Equipment Manufacturer u4VTextile Testing Instruments, Testing Equipment Manufacturer Electronic Universal Testing Machine Testing Method:
u4VTextile 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. u4VTextile Testing Instruments, Testing Equipment Manufacturer
