RTCA DO-160 Section 6 Humidity Environmental Testing
The RTCA DO-160 standard is a key document that defines environmental testing requirements for aviation electronic equipment. Section 6 focuses specifically on humidity testing, which plays an essential role in ensuring the reliability and durability of aerospace components under varying climatic conditions.
Humidity tests are critical because they help identify potential failure modes associated with moisture intrusion into electronics, which can lead to corrosion and degradation over time. This service ensures that materials like copper and brass used in avionics meet stringent performance criteria. The testing process involves exposing specimens to controlled humidity levels for extended periods under various temperatures.
Copper and brass are widely utilized in aerospace because of their excellent electrical conductivity, strength, and corrosion resistance properties. These metals are often found in wiring harnesses, connectors, fasteners, and structural parts. To ensure these materials perform reliably throughout the entire lifecycle of an aircraft, they must undergo rigorous environmental stress tests.
The RTCA DO-160 Section 6 test protocol specifies detailed procedures for simulating real-world conditions that components might encounter during storage or operation aboard commercial airliners and military aircraft. Compliance with this standard helps manufacturers demonstrate adherence to quality assurance practices recognized globally by regulatory bodies such as the Federal Aviation Administration (FAA) in the U.S.
The testing process typically consists of several stages, including preconditioning, conditioning, aging, and final qualification tests. During these phases, specimens are exposed to different relative humidity levels ranging from 10% RH up to 95% RH. Specimen preparation involves cleaning, drying, mounting onto test fixtures, and applying appropriate protective coatings if necessary.

Why It Matters
The importance of RTCA DO-160 Section 6 testing cannot be overstated, especially for materials like copper and brass used in aerospace applications. Humidity can have detrimental effects on these metals over time, leading to oxidation or galvanic corrosion between different metal alloys present within assemblies.
By conducting thorough humidity tests, manufacturers can identify any weaknesses early on in the development cycle before products reach end users. This proactive approach not only enhances product longevity but also reduces warranty costs and improves customer satisfaction.
Moreover, compliance with this standard demonstrates a company’s commitment to maintaining high-quality standards throughout its supply chain. It reassures customers that they are investing in robust solutions designed to withstand harsh conditions encountered during flight operations. This can translate into increased market share among competitors who may not adhere strictly to industry best practices.
From a regulatory perspective, meeting these requirements ensures that products meet international standards set forth by organizations like the FAA or EASA (European Aviation Safety Agency). Adherence to such guidelines provides peace of mind knowing that your product has been subjected to rigorous scrutiny ensuring its suitability for use in demanding environments.
