RTCA DO-160 Section 6 Humidity Testing
The RTCA DO-160 series of standards is widely recognized in the aerospace and aviation industry as essential guidelines for the design, construction, and testing of aircraft equipment. Specifically, DO-160 covers environmental conditions that may affect avionics systems during their operational life span. Among its numerous sections, Section 6 focuses on humidity-related tests to ensure that electronic components perform reliably under various moisture conditions.
The importance of this section cannot be overstated; it addresses the critical issue of corrosion and degradation caused by exposure to high levels of humidity. Moisture can penetrate into electronics through gaps, joints, or other openings, leading to short circuits, insulation breakdowns, and failure of components. By adhering to DO-160 Section 6, manufacturers ensure that their products meet stringent requirements ensuring longevity and safety in real-world conditions.
To achieve compliance with these standards, rigorous testing protocols are employed using specialized equipment designed to simulate extreme environmental scenarios. These tests involve exposing specimens to controlled humidity levels while monitoring electrical performance parameters such as resistance changes, capacitance variations, and overall behavior of the system under test. The ultimate goal is to identify any potential weaknesses or vulnerabilities before they become operational issues.
In addition to testing individual components, complete assemblies are often subjected to similar procedures to assess how well they function together when exposed simultaneously to harsh environmental factors like humidity. This holistic approach ensures that not only do the parts themselves survive but also that their integration into larger systems remains robust against adverse influences.
Given the complexity involved in conducting these tests, it is crucial for organizations undertaking such work to possess expertise and proper facilities capable of replicating realistic operational environments accurately.

Applied Standards
The primary standard applied during RTCA DO-160 Section 6 humidity testing is the document titled "Environmental Conditions and Test Methods for Airborne Equipment & Guide to Environmental Testing." This document provides detailed guidance on how to conduct tests that mimic real-world conditions experienced by avionics systems. Compliance with this standard ensures consistency across different manufacturers' products, facilitating interoperability between various components used in aircraft.
Specifically, DO-160 Section 6 addresses the effects of humidity on electronic devices and assemblies. It prescribes specific test methods for evaluating moisture resistance, which include both static and cycling tests. Static testing involves exposing samples to high relative humidity levels for extended periods, while cycling tests involve repeated exposure to varying humidity levels over time.
The standard also specifies acceptance criteria based on key performance indicators such as insulation resistance, dielectric strength, and leakage current measurements. These parameters are crucial in determining whether a device can withstand prolonged exposure to moisture without degrading its electrical properties significantly.
Benefits
- Enhanced Product Reliability: By adhering to RTCA DO-160 Section 6, manufacturers can ensure their avionics systems are durable and reliable even in challenging environmental conditions.
- Increased Customer Confidence: Compliance with these stringent standards instills confidence among buyers regarding the quality and performance of purchased products.
- Avoidance of Product Failures: Testing according to this standard helps identify potential weaknesses early on, preventing costly recalls or failures in use.
