1. Environmental Reliability Testing
High and Low Temperature Test
-
Purpose: To evaluate performance at extreme temperatures (e.g., -40°C to 85°C / -40°F to 185°F).
-
Method: Devices are stored at both high and low temperature conditions for over 2 hours.
-
Standard: Based on GB/T 2423.1 & 2423.2.
Thermal Cycling Test
-
Purpose: To simulate rapid temperature shifts.
-
Method: Devices cycle between -40°C and 85°C every 30 minutes for up to 100 cycles.
-
Standard: GB/T 2423.22.
Constant Humidity Test
-
Purpose: To check resistance to moisture and humidity.
-
Method: Devices are tested at 40°C (104°F) and ≥85% RH for 96 hours.
-
Standard: GB/T 2423.3.
Salt Spray Test (Corrosion Resistance)
-
Purpose: To test the corrosion resistance of metal components.
-
Method: 5% salt solution is sprayed continuously for 24 hours.
-
Standard: GB/T 2423.17.
UV Light Resistance Test
-
Purpose: To simulate long-term sunlight exposure.
-
Method: Devices are exposed to strong UV radiation for 72 hours.
-
Standard: GB/T 2423.24.
IP Water & Dust Resistance Test
-
Purpose: To validate ingress protection (e.g., IP67 or IP68 rating).
-
Method: Devices are submerged in water and exposed to fine dust per IEC/GB standards.
-
Standard: GB/T 4208.
2. Mechanical Reliability Testing
Drop Test
-
Purpose: To simulate accidental drops.
-
Method: Dropping from 1 meter (3.3 ft) onto a hard surface multiple times.
-
Standard: GB/T 2423.8.
Micro-Drop & Soft Press Tests
-
Micro-drop: Simulates minor desktop falls (500 cycles).
-
Soft press: Tests frame strength under light pressure.
Compression & Shock Test
-
Purpose: To test structural integrity under pressure or impact.
-
Method: Static force of 100N or shock of 50g over 11ms.
-
Standard: GB/T 2423.5.
Vibration Test
-
Purpose: To replicate transport and daily vibration scenarios.
-
Method: Vibration range 10–500 Hz along 3 axes.
-
Standard: GB/T 2423.10.
Surface Abrasion Test
-
Purpose: To test resistance of the screen and casing to scratches.
-
Method: Continuous friction with hard surfaces (like sandpaper or stone) for 2 hours.
3. Electrical Reliability Testing
Voltage Fluctuation Test
-
Purpose: To ensure proper function under unstable voltage.
-
Method: Simulate ±10% fluctuation from rated power.
-
Standard: GB/T 17626.11.
Battery Safety and Life Cycle Test
-
Purpose: To prevent leakage, swelling, or explosion under abnormal conditions.
-
Method: Overcharge, short circuit, over-discharge, puncture testing.
-
Standard: GB 31241.
Interface & Functional Test
-
Includes: USB port, headphone jack, microphone, speaker, flashlight, and camera.
-
Also tests: Touchscreen sensitivity, display brightness, swipe durability, and fingerprint accuracy.
4. Special Structure & Brand-Specific Tests
For models like OPPO Reno with motorized pop-up cameras, specific tests include:
-
200,000 pop-up cycles.
-
Functionality under extreme temperature and humidity conditions.
-
Salt fog exposure, elevation simulation, and dust cycling tests for internal motors.
