What are the standards corresponding to the reliability testing items for automotive electronic components?

  1. Environmental Reliability Testing:
    • Temperature Tests:
      • Low Temperature Test: Standards such as GB/T 2423.1, IEC 60068-2-1, ISO 16750-4, GMW 3172, and GB/T 28046.4 can be applied. Different standards may have different regulations on parameters such as the temperature range, duration, and temperature change rate under low temperature conditions.
      • High Temperature Test: Commonly used standards include GB/T 2423.2, IEC 60068-2-2, ISO 16750-4, GMW 3172, and GB/T 28046.4. These standards are used to test the performance stability, reliability, and tolerance of automotive electronic components in a high-temperature environment.
      • Temperature and Humidity Cycling Test: Standards like GB/T 2423.34, IEC 60068-2-38, ISO 16750-4, GMW 3172, and GB/T 28046.4 can be used to evaluate the reliability of components in an environment where temperature and humidity change alternately.
      • Constant Humidity and Heat Test: Standards such as GB/T 2423.3, IEC 60068-2-78, ISO 16750-4, GMW 3172, and GB/T 28046.4 are used to verify the performance of components in an environment with high humidity and relatively stable temperature.
    • Solar Radiation Test: Standards like GB/T 2423.24, IEC 60068-2-5, and GB/T 28046.4 can simulate the situation where automotive electronic components are exposed to solar radiation outdoors and detect the performance changes under long-term sunlight exposure.
    • Salt Spray Test: Standards including GB/T 2423.17, GB/T 2423.18, IEC 60068-2-11, and IEC 60068-2-52 are used to test the salt spray corrosion resistance of components to evaluate their reliability in seaside or salt spray environments.
    • Mould Test: Standards such as GB/T 2423.16 and IEC 60068-2-10 can be used to detect whether automotive electronic components are prone to mould growth in a humid and warm environment and the impact of mould on component performance.
    • Gas Corrosion Test: Standards like GB/T 2423.51, IEC 60068-2-60, and ISO 16750-4 are used to evaluate the corrosion resistance of components in specific gas environments.
  2. Mechanical Reliability Testing:
    • Sinusoidal Vibration Test: Standards such as GB/T 2423.10, IEC 60068-2-6, and ISO 16750-3 can be used to detect the reliability of automotive electronic components in a sinusoidal vibration environment, simulating the vibration during vehicle driving.
    • Random Vibration Test: Standards including GB/T 2423.56, IEC 60068-2-64, and ISO 16750-3 are used to evaluate the performance of components in a random vibration environment, which is closer to the actual vibration situation during vehicle driving.
    • Free Fall Test: Standards like GB/T 2423.8, IEC 60068-2-31, and ISO 16750-3 are used to test the impact resistance of components when they are accidentally dropped.
    • Mechanical Shock Test: Standards such as GB/T 2423.5, IEC 60068-2-27, and ISO 16750-3 can simulate the situation when components are subjected to instantaneous mechanical shocks and examine the stability of their structures and performance.
    • Combined Environment Vibration Test: Standards such as ISO 16750-3 and GB/T 28046.3 are used to comprehensively assess the reliability of components under the simultaneous action of three environmental factors: temperature, humidity, and vibration.
  3. Electrical Performance Testing:
    • Withstand Voltage Test: Standards like ISO 16750-2 and GB/T 28046.2 are used to detect the insulation performance and withstand voltage capability of automotive electronic components to ensure that the components will not have breakdowns, short circuits, or other failures under normal working voltages and certain overvoltage conditions.
    • Insulation Resistance Test: Standards such as ISO 16750-2, GB/T 28046.2, and GMW 3172 can be used to measure the insulation resistance of components and determine whether their insulation performance meets the requirements.
    • Contact Resistance Test: The standard GB/T 5095.2 is used to test the contact resistance of components such as connectors to ensure good electrical connection performance.
    • Temperature Rise Test: The standard GB/T 5095.3 is used to detect the temperature rise of components during the working process to evaluate their heat dissipation performance and working stability.
  4. Protection Level Testing:
    • IP Protection Level Test: Standards such as GB 4208, IEC 60529, and ISO 20653 are used to determine the dustproof and waterproof levels of automotive electronic components to ensure that they can work normally under different environmental conditions.
  5. Electromagnetic Compatibility Testing:
    • ISO 7637: This standard specifies the test methods and test conditions for electromagnetic compatibility of road vehicles and is used to test the anti-interference ability of automotive electronic components in an electromagnetic environment and their electromagnetic radiation to other devices.
  6. Functional Safety Testing:
    • ISO 26262: It stipulates the functional safety requirements for automotive electronic systems, including confirming safety objectives, determining safety requirements, analyzing system-level requirements, designing system-level architectures, designing hardware and software, integrating and verifying systems, as well as management and documentation processes in the system development cycle.
Different automobile manufacturers and component suppliers may choose different standards or formulate internal enterprise standards for reliability testing according to their own needs and product characteristics. Therefore, when conducting reliability testing for automotive electronic components, it is necessary to select appropriate standards according to specific testing items and requirements.
