During this test, the tablet is exposed to a power frequency electric field from an electric field generator. The test ensures that the tablet can withstand power frequency electric field without malfunctioning.

(3) Energy efficiency test

  • Power consumption test: this test measures the tablet’s power consumption in various operating modes, such as idle, browsing, video playback, and standby. It helps determine how efficiently the tablet utilizes energy during different usage scenarios.
  • Battery efficiency test: the test assesses the tablet’s power usage when running on battery. It measures factors such as battery life, charging efficiency, and standby power consumption to evaluate how effectively the tablet utilizes its battery capacity.
  • Sleep mode power consumption test: this test measures the tablet’s power consumption when in sleep or standby mode. It ensures that the tablet enters a low-power state when not in active use, minimizing energy wastage.
  • Display power efficiency test: the test evaluates the energy consumption of the tablet’s screen. It assesses factors like brightness levels, backlighting technology, and power-saving features to determine how efficiently the tablet utilizes energy for its display.
  • Energy Star compliance test: to obtain Energy Star certification, tablets undergo comprehensive testing to ensure compliance with energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA). Energy Star-certified tablets are designed to consume less power during operation, reducing energy consumption and environmental impact.

(4) Mechanical tests

  • Drop test: the test is one of the most important mechanical tests that a tablet undergoes. This test is designed to test the durability of the tablet when it’s dropped from a certain height. The drop height varies for different tablets, but the standard height is 1.22 meters (4 feet). The tablet is dropped on different surfaces, including concrete, wood, and carpet to simulate real-life scenarios.
  • Twist test: the test is performed to test the robustness of the tablet’s housing. The tablet is clamped on both ends and twisted in opposite directions to test its resistance to torsion. The test is repeated multiple times, and the tablet is inspected for any damage after each twist.
  • Pressure test: the test is done to test the strength of the tablet’s screen. The tablet is placed on a pressure point, and a force is applied to it until the screen cracks or breaks. The force applied varies for different tablets, but the standard force is 25 pounds.
  • Vibration test: the test is designed to test the tablet’s ability to withstand vibrations. The tablet is placed on a vibration table, and vibrations are applied to it at different frequencies and amplitudes. The test is repeated multiple times, and the tablet is inspected after each test to check for any damage.

(5) Environmental tests

  • Water resistance test: the test is performed to test the tablet’s ability to withstand water. The tablet is placed in a container filled with water and left for a certain amount of time. The test duration varies for different tablets, but the standard time is 30 minutes. After the test, the tablet is inspected for any water damage.
  • Temperature test: the test is done to test the tablet’s ability to withstand extreme temperatures. The tablet is placed in a temperature chamber and subjected to different temperatures ranging from -10°C to 50°C. The test is repeated multiple times, and the tablet is inspected after each test to check for any damage.
  • Humidity test: the test is performed to test the tablet’s ability to withstand humidity. The tablet is placed in a humidity chamber and subjected to different levels of humidity ranging from 20% to 80%. The test is repeated multiple times, and the tablet is inspected after each test to check for any damage.
  • Salt spray test: the test is designed to test the tablet’s ability to withstand corrosion. The tablet is placed in a salt spray chamber and subjected to a saltwater mist for a certain amount of time. After the test, the tablet is inspected for any corrosion damage.
