Environmental reliability Damp heat test four

* Environmental reliability Damp heat test: the test samples suitable for determining the use and storage in hot and humid conditions under constant adaptability. * Test Method: * High temperature and humidity; high temperature and low humidity; low humidity; low humidity. * High temperature and humidity: 950C95% RH; * high temperature and low humidity: 950C 10% RH; * low humidity: 100C95% RH; * low humidity: 100C10% RH; * Objective: To observe the test sample at a constant temperature, no condensation, regulations Effect of time under high humidity environment; * for electronic products and more demand without packaging, no power in the "ready to use" condition. The normal operating position or in accordance with relevant state standards for work space into the chamber; * during the operation to avoid misuse and resulting condensation: 1. Temperature change rate: less than 1 K / min; the temperature is stable, 2h the humidity was adjusted to test requirements. 2. If the device by automatically adjusting from a different matter. * Recovery: over 0.5 hours to recover to 73% relative humidity - 77%; over 0.5 hours and then the temperature was adjusted to the temperature of the test chamber. * Reference Standard: IEC60068-2-78; GB / T 2423.3 measuring and testing Ltd.
