Testing Products for ASTM D5169
APP-D5169Measures the sliding shear strength of Velcro-style fasteners. This configuration focuses on the Newton-Series control architecture to ensure high-fidelity data acquisition. Utilizing a 32-bit digital signal processor, the system provides a superior Signal-to-Noise Ratio (SNR), which is essential for capturing precise material transitions that lower-resolution systems often miss.
The load frame for this application has been selected to provide the most cost-effective solution capable of meeting the standard’s peak force requirements. While TestResources offers a wide range of frame geometries, this specific selection represents the optimal balance between laboratory CAPEX and technical compliance. Any frame in our catalog meeting the minimum load rating will adhere to the standard; however, this configuration is our primary recommendation for those seeking a reliable, streamlined testing platform without unnecessary complexity.=
The 5lb Roller: The bond of Velcro is only as good as the pressure used to close it.
Use an Automated 2kg Roller to ensure every specimen is engaged with the exact same pressure.

Implementation Commentary
This measures Lateral Shear. For Peel strength of the same material, you must use ASTM D5170.
Common Pitfalls
Re-using the same Hook side for multiple Loop tests; the hooks dull after a single high-force pull.
