Testing Products for ASTM D732
APP-D732Measures shear strength of sheet plastic using a punch and die setup. 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.=
Tool Clearance: The gap between the punch and the die must be precisely maintained to avoid burring.
Use a rigid, high-force compression frame; any frame deflection will result in an uneven shear cut.

Implementation Commentary
Unlike tensile shear, punch shear provides data on how materials behave during manufacturing (stamping).
Common Pitfalls
Testing specimens of different thicknesses without adjusting the punch-to-die clearance.
