IEC 60068 Environmental Testing of Electrical Components
The IEC (International Electrotechnical Commission) standard 60068 is a comprehensive suite of tests designed to evaluate the environmental robustness of electrical components used in railway and transportation systems. This service ensures that the components can withstand harsh environmental conditions, including temperature variations, humidity, vibration, altitude changes, and more.
Our state-of-the-art laboratory adheres strictly to IEC 60068 standards, providing precise testing for electrical components such as relays, connectors, circuit breakers, and power supply units. These tests are crucial in ensuring that railway equipment operates reliably under extreme conditions, thereby enhancing safety and performance.
The service involves a series of environmental stress tests to determine the limits of component durability. Key parameters include temperature cycling, humidity testing, salt fog exposure, vibration testing, and more. Each test is conducted with meticulous precision, ensuring that every component meets stringent quality standards.
For instance, in temperature cycling tests, components are subjected to rapid changes between extremes (e.g., -40°C to +85°C), replicating the operational environment they will experience throughout their lifecycle. Humidity testing ensures resilience against moisture ingress, which can lead to corrosion and electrical shorts.
Vibration testing simulates the mechanical stress components endure during transportation and operation on railway tracks. This is essential for ensuring that connectors remain secure and reliable under dynamic conditions. Salt fog exposure tests assess a component's resistance to salt spray, a critical factor in coastal environments or areas with high road salt usage.
We use advanced instrumentation and specialized chambers tailored to IEC 60068 requirements. Our team of experts ensures that each test is conducted under controlled conditions, replicating real-world scenarios as accurately as possible. The results are meticulously recorded and analyzed, providing comprehensive reports with detailed pass/fail criteria.
| Test Type | Description |
|---|---|
| Temperature Cycling | Components are exposed to rapid temperature changes, simulating operational environments. |
| Humidity Testing | Evaluates resilience against moisture ingress and corrosion. |
| Vibration Testing | Assesses mechanical stress under dynamic conditions. |
| Salt Fog Exposure | Tests resistance to salt spray in coastal or road-salting environments. |
