Lifecycle, Stability, and Durability Testing Long-term reliability is validated through: Lifecycle testing , simulating up to 4,500 operational cycles1.5 the expected product lifespan Cyclic testing under alternating temperature extremes Accelerated aging and stability verification , supporting shelf lives of 1, 3, and 5 years Knob performance and torque testing , ensuring consistent tactile and auditory feedback throughout product life Safety & User Protection Validation Patient and user safety are validated through dedicated testing of: Needle compatibility and secure attachment Pen cap removal force Needle safety device activation and locking strength Needle safety distance and insertion depth Injection time and leakage control , with leakage levels well below allowable limits Visual, auditory, and tactile feedback mechanisms are also inspected to ensure users receive clear confirmation during dose setting and injection
