Cap/Closure Torque Strength Testing for Beverage Bottles

Mineral water, carbonated soft drink and alcoholic beverage is usually packaged in a variety of sizes of plastic (PET) bottles and it is essential that the caps on their bottles are easy to open, while at the same time applied tightly enough to ensure the bottles do not leak.

To guarantee the quality of their packaging, manufacturers of beverage should test their bottles compliance with domestic and international standards.

International Standards 

• ASTM D2063 -- Standard Test Methods for Measurement of Torque Retention for Packages with Continuous Thread Closures Using Non-Automated (Manual) Torque Testing Equipment
• ASTM D3198 -- Standard Test Method for Application and Removal Torque of Threaded or Lug Style Closures
• ASTM D3474 -- Standard Practice for Calibration and Use of Torque Meters Used in Packaging Applications
