SATRA STM 507 Digital Footwear Stiffness Tester

Product Information 

Torsional stiffness is a measure of the resistance to twisting of footwear about its longitudinal axis. The footwear is clamped in the toe area, forces are applied through the heel clamp such that the heel and backpart is twisted first inwards and then outwards up to a maximum angle. The torque required to achieve the twist is used to calculate the torsional stiffness values.

Operation procedure

1.Turn on the power, press the "Down" button, let the moving board back to 0-bit.

2. Install the sample (shoe or shoe sole), and place the zigzag line of the sample on the rotating shaft to compress the toe cap;

3. Press the “clear” button on the display to display 0.00 kg on the display.

4. Press the "Up" button, the table to the specified speed (100±10mm/min) gradually increase the force to 3kg or the active plate bends to 90°, the instrument will automatically stop. At this point, we can look at the angle of the pointer readings, according to which we decide whether it is to do the folding test;

5. When we measure the rigid angle of the shoe, press the "Down" button again to return the movable panel to zero (level). Repeat the above steps for a sample test;

6. After testing, please turn off the power.

Attention matters

1. The instrument must be reliable grounding

2. Regularly in the activities of the instrument to add embellish oil to protect the flexibility of the use of equipment

3. The instrument must be used by special personnel

4. External power supply: AC220v.

5. Power: 100W

Standard

Comply with ISO EN20344-2010 and other standards.

What is the purpose of footwear testing?
Testing the materials and components that make up the finished product, as well as evaluation of the complete shoe, helps ensure safety compliance, reduce returns, improve quality and enhance customer loyalty and satisfaction.
