Salt Spray Cabinet Climate Simulation Test for Small Components
The Salt Spray Cabinet Climate Simulation Test is a critical method used to evaluate the resistance of small electronic components, such as connectors, switches, and relays, against corrosion caused by salt exposure. This test simulates the harsh environmental conditions that these components may encounter during their operational lifecycle.
The primary objective of this test is to provide insights into how well the materials used in the construction of the small components will perform under extreme humidity and corrosive environments. The test involves exposing the component to a salt spray environment for a specified period, typically 48 hours or longer, depending on the required standard.
The process begins with thorough preparation of the specimen. Components are carefully cleaned and dried before being placed in the cabinet. During testing, the temperature is controlled within a specific range, often between 35°C to 50°C, while maintaining a relative humidity above 95%. The salt solution used for the test typically contains sodium chloride (NaCl) dissolved in distilled water.
The acceptance criteria are based on industry standards such as ISO 12944. A pass/fail decision is made by observing any changes or deterioration of the component’s surface, including rusting, pitting, and other signs of corrosion. Any deviation from the original appearance can indicate insufficient resistance to salt spray.
| Parameter | Specification |
