*2.5. Tray Damage Assessment*

At the completion of each drop test, the trays were visually inspected for damage sustained during the mechanical shock testing. The condition of the tray was graded using a qualitative assessment based on the level of damage (i.e., tearing and cracking). The scale used to grade the condition after the drop test was poor (severe damage), fair (moderate damage), or good (minor damage) based on the damage level.
