MIL STD 202 Method 106 Moisture Resistance Environmental Test
The MIL STD 810G, Method 106 of the Military Standard, is a widely recognized and rigorous testing protocol designed to evaluate the moisture resistance capabilities of electronic components and assemblies. This test simulates real-world environmental conditions where moisture exposure can significantly impact the performance and reliability of electronics. Compliance with this standard ensures that products are robust against moisture ingress during storage, shipping, or use in various environments.
The procedure involves subjecting the product to a series of humidity cycles followed by thermal conditioning. The test aims to simulate the effects of prolonged moisture exposure, ensuring that the electronic devices can withstand such conditions without failing. This is particularly important for products destined for harsh environmental conditions like military applications or regions with high humidity.
The testing process typically begins with careful preparation of the specimens. Each component must be labeled accurately and its electrical characteristics recorded before testing. Specimens are then placed in a controlled environment where they undergo various cycles of temperature changes, combined with varying levels of humidity. The duration and conditions of these cycles can vary depending on specific requirements but generally follow the parameters set out by MIL STD 810G.
Once the tests conclude, thorough inspection is conducted to assess any damage or degradation in performance caused by moisture exposure. Any changes that might indicate failure must be documented meticulously. This includes checking for signs of corrosion, insulation resistance drop-offs, and other indicators of moisture-related issues. The results are then compared against established acceptance criteria laid down by MIL STD 202.
This method is crucial in ensuring the long-term reliability and durability of electronic devices under challenging environmental conditions. By adhering to these stringent tests, manufacturers can demonstrate compliance with industry standards, thereby enhancing their products' marketability and trustworthiness among users who operate them in demanding environments.
For those interested in implementing this testing method for their own products or services, it is essential to consult with experienced laboratories that specialize in environmental simulation testing. These labs possess the necessary expertise and equipment to accurately perform these tests according to MIL STD 202 specifications.

Scope and Methodology
The MIL STD 202, Method 106 test encompasses several key aspects that ensure comprehensive evaluation of moisture resistance. The scope includes both laboratory conditions where controlled variables are maintained to simulate real-world scenarios accurately.
- Humidity Cycles: Specimens are exposed to varying levels of humidity over extended periods to mimic the effects of prolonged moisture exposure.
- Thermal Conditioning: Products undergo temperature fluctuations designed to reflect typical operational conditions they may experience in field use.
- Specimen Preparation: Before testing, each component is carefully labeled and its initial electrical performance documented. This ensures accurate comparison post-testing.
- Data Collection & Analysis: Throughout the test cycle, detailed records are kept regarding any changes observed in the specimens' behavior or performance.
The methodology involves not only exposing the products to these environmental conditions but also closely monitoring them through various stages of testing. This allows for precise assessment of how well each item withstands moisture-related stresses.
By adhering strictly to MIL STD 202 guidelines, laboratories ensure that their tests are both reproducible and consistent with international standards. This consistency is vital for maintaining credibility among clients who rely on such testing results to make informed decisions about product quality.
Quality and Reliability Assurance
- Compliance Verification: Rigorous adherence to MIL STD 810G ensures that all tests meet the required standards, providing assurance of product quality.
- Data Integrity: Detailed records are maintained throughout each test cycle, ensuring accurate documentation for future reference or audits.
- Continuous Improvement: Post-test analysis helps identify potential areas where improvements can be made to enhance moisture resistance further.
- Client Satisfaction: By delivering reliable and consistent results, clients gain confidence in the reliability of their products.
