The SATRA TM92 is a footwear testing method developed by SATRA (Shoe and Allied Trades Research Association) to evaluate the flexing resistance of footwear materials and components. SATRA is a leading research and testing organization in the footwear and leather goods industry.
The SATRA TM92 method specifically focuses on the flexing resistance of shoe uppers. It assesses the ability of the upper material to withstand repeated flexing motions that simulate walking or other activities. The test is performed using specialized footwear testing equipment designed for flexing resistance testing.
The main objective of the SATRA TM92 flexing resistance test is to determine the point at which cracks or other forms of damage occur in the upper material due to flexing stress. By subjecting the upper material to controlled flexing movements, the test provides valuable information on the material's durability and potential lifespan under real-world conditions.
The specific equipment used for the SATRA TM92 flexing resistance test is known as the Footwear Testing Equipment For Flexing Resistance Test. This equipment typically includes the following components:
1. Flexing Apparatus: The flexing apparatus consists of two clamps or grips that securely hold the upper material. One clamp is stationary, while the other is attached to a motor-driven arm. The arm moves back and forth, causing the upper material to flex repeatedly.
2. Flexing Frequency and Angle Adjustment: The equipment allows for the adjustment of flexing parameters, such as the flexing frequency and flexing angle. The flexing frequency determines how many flexing cycles are performed per minute, while the flexing angle determines the degree to which the upper material is flexed during each cycle.
3. Observation and Evaluation: During the flexing resistance test, the upper material is visually inspected at regular intervals or after a certain number of flexing cycles. The appearance of cracks, material delamination, or other forms of damage is assessed. The number of flexing cycles required for the upper material to exhibit visible damage is recorded as an indication of flexing resistance.
The SATRA TM92 flexing resistance test provides valuable information for footwear manufacturers, material suppliers, and quality control laboratories. By evaluating the flexing resistance of shoe uppers, it helps in the selection of suitable materials, design optimization, and quality assurance of footwear products.
It's important to note that the specific design and features of the Footwear Testing Equipment For Flexing Resistance Test may vary depending on the manufacturer and model. When conducting the SATRA TM92 flexing resistance test, it is essential to follow the standardized testing procedures and guidelines provided by SATRA or other relevant industry organizations to ensure accurate and consistent results.
