Testing Products for ASTM D412
APP-D412Evaluates the tensile properties of thermoset rubbers and thermoplastic elastomers. It focuses on ultimate elongation, tensile set, and tensile strength.
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.
High Elongation: Rubbers can stretch 500% to 1000% before breaking.
Use Long-Travel Extensometers or non-contact Video Extensometers to track high strain.

Implementation Commentary
Rubbers thin out significantly during the test; manual grips will allow the sample to slip.
Common Pitfalls
Use Pneumatic Side-Action Grips to maintain a constant clamping pressure as the sample necks.
