ASTM D7860-14 Torque Retention for Child Resistant Packaging
The test methods described in ASTM D7860-14 are intended to measure torque retention properties of threaded closures such as child-resistant and non-child resistant medical packaging.
Reported results of ASTM D7860-14 include the application torque range and average application torque per test specimen, as well as the removal torque range and average removal torque per test specimen. In addition to these parameters, it is required to report axial applied force for closures if applicable.
An Electromechanical system with a torsion add-on can be used to perform these tests. The Torsion Add-On 2.0 can be added to any 5900 or 6800 Series single column testing machine to add rotational capabilities. The system operates on Instron’s Bluehill® Universal software with TestProfiler. Bluehill Universal is able to perform closed-loop control for axial testing and measures axial displacement, rotary displacement, axial load and torque. A biaxial Dynacell load cell is mounted to the base of the machine. Advanced screw action grips are used to grip the bottle and bottle cap. A slight axial load can be placed on the bottle cap to push it down before rotation begins.
Torsion Add On 2.0 for Electromechanical Systems
The Instron® Torsion Add-On 2.0 for Electromechanical Universal Testing Systems is designed for simple, simultaneous axial and torsional testing of devices and/or components, but has the flexibility to be used for purely uni-axial or torsional testing.
