Durability Testing of Key Components
Repeatedly operate controls-such as setting mechanisms and function buttons-thousands of times to simulate long-term use; verify that there is no sticking or malfunction and that timekeeping and alarm functions remain consistent.
Environmental Adaptability Verification
Subject the alarm clock to static exposure in temperature extremes (ranging from -10°C to 40°C) and standard humidity levels, then confirm that timekeeping, display, and alarm functions remain unaffected.
Long-Term Stability Assessment
Operate the alarm clock continuously (via mains power or batteries) for several weeks; record battery life and verify the absence of timekeeping drift or functional failures throughout the period.
Exterior and Structural Inspection
Check that the housing is made of high-quality, wear-resistant, and drop-proof materials (such as ABS); ensure the casing design is robust and resistant to paint chipping or cracking from minor daily impacts.
