►Specification
| Characteristics | Value/Performance | Methods and Conditions |
| Mechanical | ||
| Air Tightness | No air bubble seen | Put closure under water for 15min with closure's internal air pressure set at 100kPa±5kPa. |
| Remains100kPa±5kPa | Measure the internal pressure 24 hours later | |
