Test Procedure

  1. Pre-test inspection: Visually inspect all 3 samples for pre-existing damage; record appearance baseline and verify power-on and charging function are normal.
  2. Environment conditioning: Confirm laboratory temperature is 22 °C and relative humidity is 55 % RH before testing.
  3. Mounting: Load the sample into the single-arm drop testing machine. Set drop height to 100 cm.
  4. Drop sequence: Execute one drop for each of the 6 faces (Face 1 through Face 6), for a total of 6 drops per sample unit.
  5. Post-drop visual inspection: Immediately after each drop, inspect the sample for cracks, deformation, fractures, or any structural damage to housing components.
  6. Functional verification: After all 6 drops, power on the device and verify normal operation; connect charger and verify normal charging.
  7. Acceptance criteria: Structural components must show no damage, cracking, or deformation. Power-on function and charging must operate normally.

Test Data & Results

Stage Observation
Before drop Samples inspected prior to testing — appearance normal
Drop sequence (Faces 1–6) 6 drops executed: Face 1, Face 2, Face 3, Face 4, Face 5, Face 6
Post-drop — Appearance No structural breakage; minor surface damage to bottom cover
Post-drop — Power-on function Normal
Post-drop — Charging Normal

Test result summary (as recorded): After a 100 cm single-arm drop test, the HB2 sample showed no breakage to its exterior; the bottom cover sustained minor surface damage. Power-on function was normal and charging was normal.
