IEC 60068 2 68 Sand and Dust Simulation Testing Validation Method Development Test
The IEC 60068-2-68 standard specifies a method for simulating the effects of sand and dust exposure on electronic equipment. This test is crucial in ensuring that marine and shipboard equipment can withstand harsh environmental conditions, particularly those encountered during operation at sea or in coastal areas.
The test involves exposing specimens to a combination of sand particles and air flow under controlled conditions to simulate natural environments where sand and dust are prevalent. The goal is to validate the design and material choices made for equipment used in marine and shipboard applications. This testing method plays a vital role in enhancing the reliability, durability, and safety of such equipment.
The primary focus areas include:
- Material integrity
- Electrical performance under sand and dust conditions
- Functional integrity of mechanical components
- Surface finish degradation due to abrasive materials
Testing is performed in a specially designed chamber where environmental parameters are carefully controlled. The test setup includes:
- A sand flow system that simulates wind-blown dust conditions
- An air flow system to control the velocity and direction of airflow
- Sensors to monitor temperature, humidity, and particle size distribution
The specimen preparation involves selecting representative samples of the equipment under test. These samples are then mounted in a manner that replicates real-world usage conditions as closely as possible.
Upon completion of the test, detailed reports are generated outlining:
- Test parameters and environmental conditions
- Observations during testing
- Data collected from sensors
- Evaluation of specimen integrity and performance
The IEC 60068-2-68 test is essential for ensuring that marine and shipboard equipment meets international standards, thereby enhancing the overall safety and reliability of these systems.
| Test Parameter | Environmental Condition | Measurement |
|---|---|---|
| Sand Particle Size Distribution | Controlled by ISO 14688-2 | Mean diameter and standard deviation |
| Air Flow Velocity | 0.5 m/s to 3 m/s | Measured using an Anemometer |
| Test Duration | Up to 96 hours | Dependent on specimen response |
| Temperature | -25°C to +40°C | Monitored with a thermocouple |
| Humidity | 30%RH to 85%RH | Measured using a humidity sensor |
This testing method is widely recognized for its role in ensuring that equipment used in marine and shipboard applications can withstand the rigors of environmental exposure. Compliance with IEC standards ensures that products meet global quality and safety benchmarks.
