Measure closing and opening torques according to ASTM D3198
Screw caps: Easy for everyone to open and still tight?
Determining the ideal torque for screw caps
Whether minimum closure or opening torque, we are equipped and qualified to determine this value. We generally perform the measurements in accordance with ASTM D3198 (Application and Removal Torque of Threaded or Lug-Style Closures).
The measurements can be performed regardless of the shape of your screw closures, so special solutions such as for twist-off closures are also possible.
Sensible application areas for torque measurements:
- Food
- Pharmaceutical products
- Dangerous goods
- Engine oils
- Plant protection
In addition, we can also check the tightness for you under special transport loads, such as negative pressure in an aircraft.
