The sand and dust test chamber follows the military standard GJB150.12A-2009, which outlines three distinct procedures: Program 1 involves blowing dust, Program 2 is for blowing sand, and Program 3 focuses on dusting. Choosing the appropriate procedure depends on several factors. Yashilin provides a detailed explanation to help you decide:
When selecting the test procedure for a sand and dust test chamber, military standards should be taken into consideration. Here are key factors to consider:
1. **Purpose of the Equipment**: Based on relevant documentation, identify what functions the equipment must perform in a sand or dust environment, as well as under storage conditions.
2. **Natural Exposure Conditions**: Consider real-world environments where the equipment might be used. This helps determine the most suitable test method that simulates actual operating conditions.
3. **Required Test Data**: Determine what data is needed to evaluate whether the equipment meets performance requirements. Different procedures may yield different types of data, so it's important to align with your testing goals.
4. **Order of Procedures**: If the same test sample is used for multiple procedures, it's generally advisable to start with the least harmful one. For example, perform dusting or blowing tests first, followed by sand blowing, to avoid damaging the equipment before more severe tests.
By carefully considering these factors, you can ensure that the selected test procedure accurately reflects the operational challenges your equipment may face in real-world scenarios. This not only improves the reliability of the test results but also ensures compliance with military specifications.
