ASTM D2063 Torque Retention for Packages with Continuous Thread Closures

ASTM D2063 test method evaluates the torque retention of continuous thread closures of containers. As an ISTA and ISO 17025 certified lab, we realize the importance of continuous thread closure testing. Meeting the ISTA D2063 requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone provides constant communication throughout the test process. We also prepare comprehensive reports shortly after the completion of the testing. When packages do not meet the requirements, we assist with finding solutions. Our proven process helps avoid product launch delays.

Summary of ASTM D2063 Torque Retention Package Testing

This ASTM D2063 test method allows for the measurement of the torque retention properties of a container thread system with various designs, materials, and manufacture. This method is also a test standard to establish thread closure systems under controlled conditions.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. Also, they may not be exact equivalents. Therefore, each system is used independently of the other.

Scope of ASTM D2063 Non-Automated Torque Testing

There are two methods that can be used within the test standard. Test method A involves static evaluation. Test method B uses dynamic evaluation.

Within test method A, at predetermined time intervals, the removal torques are measured. This method represents previously-stored thread closure systems at various environmental conditions.

Test method B uses ASTM D4169 to develop a uniform system of evaluating the ability of primary packages. This is used in shipping units to withstand the distribution environment. At the end of the predetermined distribution cycles, the removal of torques of a continuous thread is measured.

These test methods allow the user of this standard to address all of the safety measurements of the torque retention properties. This is suitable for packaging development and engineering evaluations.

Significance of Continuous Thread Closures Using Non-Automated Torque Testing Equipment

Conditioning and preparation of test specimens are major key points to performing ASTM D2063 testing. No less than 10 test specimens are measured for each torque measurement point per test variable. The spring torques are calibrated in accordance with the procedures of ASTM D3474.

Test A and B procedures are both performed to conclude valuable information within the test results.

To carry out test procedure A, the minimum application torque for the container thread system is selected. This application is recommended by the closure manufacturer. Next, the container is firmly positioned in such a manner that the axis of rotation is concentric with the center of the torque measuring device. The movable component is then released upon reaching the desired torque.

One test group is maintained as a control by storing the group at ambient laboratory conditions. The maximum torque required to loosen the closure is recorded. Lastly, the balance of movable components is removed and recorded as well.
