ADIDAS ST-05 Test Fixtures & Test Systems Model: G-ADIDAS-ST-05
Strain Accuracy in Polymers: For ADIDAS ST-05, the precision of the Class B-1 calibration is paramount. In footwear material testing, the high elongation of synthetic polymers often leads to knife-edge slippage.

Expert Commentary
The Seating Load Protocol: In the context of ADIDAS ST-05, the mechanical interface between the extensometer and the specimen is the primary source of error. Because athletic textiles and foams are highly compliant, traditional clip-on sensors can pinch the material, creating a local stress riser that causes premature failure. The fixture and sensor integration must be perfectly vertical to avoid gravitational sag on the extensometer arms. Without a seating load to tension the load train, the initial modulus data will be skewed by mechanical noise or take-up in the grips, leading to inaccurate energy return calculations.
