Whole Shoes Flexing Tester Test Method

The Whole Shoes Flexing Tester is a specialized testing equipment used to assess the flex resistance and durability of shoes. This test method evaluates the ability of shoes to withstand repeated bending and flexing motions, simulating the normal wear and tear they may experience during use. In this test, the shoes are subjected to controlled flexing movements, and various parameters are measured and analyzed to determine the footwear's performance and quality.

Here is a detailed description of the Whole Shoes Flexing Tester test method, explaining the testing procedure, equipment setup, and key parameters measured:

1. Equipment Setup:

   - The Whole Shoes Flexing Tester consists of a testing chamber or compartment specifically designed to accommodate footwear.

   - The shoe upper, including the vamp and heel area, should be secured to the testing apparatus using clamps or other suitable fixtures. The shoe sole remains free to flex naturally during testing.

   - The tester is equipped with a mechanism to provide controlled flexing motions to the shoes, simulating walking or bending movements.

   - The test apparatus may include sensors, such as strain gauges or displacement transducers, to measure and record parameters during testing.

2. Specimen Preparation:

   - Select representative shoes for testing, ensuring they are in the proper size and condition.

   - Prepare the shoes by removing any excessive dirt, debris, or loose threads that may interfere with the flexing motion.

   - Take necessary precautions to avoid damaging the shoes during specimen preparation.

3. Test Procedure:

   - Place the prepared shoe specimens in the testing chamber, securing the upper part while allowing the sole to flex freely.

   - Set the desired testing parameters, such as flexing angle, flexing speed, and number of flex cycles, according to the test requirements or relevant standards.

   - Start the flexing motion and allow the shoes to undergo the specified number of flex cycles.

   - Monitor and record any observable changes or signs of damage during testing, such as cracks, delamination, or detachment of materials.

   - Stop the test after completing the specified number of flex cycles.

4. Parameters Measured:

   - Flexing Angle: The angle formed by the maximum displacement of the shoe during flexing. It indicates the extent of flexing of the shoe.

   - Flexing Speed: The rate at which the shoe is flexed during testing, typically expressed in cycles per minute (CPM). It determines the speed of the simulated walking or usage scenario.

   - Number of Flex Cycles: The total number of flexing motions applied to the shoe during the test. It reflects the durability and ability to withstand repetitive flexing.

   - Damage Analysis: Evaluate the shoe's performance based on visible damages, such as cracks, material deformations, sole delamination, or seam failures. (This analysis is subjective and may require expert judgment.)

5. Data Analysis and Reporting:

   - Analyze and summarize the collected data, including any observations, measurements, and damages incurred during testing.

   - Evaluate the performance of the shoe specimens based on the test parameters and requirements specified in relevant standards or specifications.

   - Generate a test report that includes the test setup, testing parameters, test results, and any observations or recommendations.

It is important to note that the above-described test method is a general outline and may vary depending on the specific test standard or specifications followed. It is recommended to consult the relevant testing standard or professional guidelines for detailed testing procedures and accurate interpretation of results.
