Testing Products for ASTM D2979
APP-D2979Measures the stickiness or tack of an adhesive using a 5mm diameter probe. 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 Quick Stick: Measures how much force is needed to pull a 5mm probe away from a sticky surface.
Use your Sensotec Model 31 (50g) here. The force of tack is often less than the weight of a penny.

Implementation Commentary
Critical for Band-Aid and surgical tape manufacturers to ensure it sticks instantly to skin.
Common Pitfalls
A dirty probe tip. Even a single skin-cell or dust-mote will drastically lower the recorded tack force.
