Testing Products for ASTM D5733
APP-D5733Specifically for non-woven textiles; determines the force required to continue a tear. 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 Notch: The tear must follow the fibers; the trapezoid shape forces the tear across a wider area.
Use wide grip faces (at least 3″ wide) to ensure the entire trapezoid width is clamped securely.

Implementation Commentary
This is a toughness test for materials like house-wrap (Tyvek) or protective PPE gowns.
Common Pitfalls
Notching the specimen too deep or too shallow, which changes the tear initiation energy.
