MIL-STD-810 Humidity Compliance Testing

High humidity can occur in various environments year-round. These conditions bring several short-term and long-term effects on material. Usually, basic high humidity conditions only occur briefly or seasonally in mid-latitudes.

However, one of two high humidity cycles occur almost constantly in heavily forested areas during rainy and wet seasons. The two humidity cycles are defined as constant high humidity and cyclic high humidity. Exposed materials are likely to be constantly wet for many days at a time.

As a MIL-STD-810 certified lab, we realize the importance of military lab testing. We understand the challenges of meeting MIL-STD 810 compliance and guide companies through the process.

Keystone Compliance partners with customers to achieve MIL-STD-810 product compliance. Additionally, our pricing is competitive and we offer volume discounts. Keystone takes a consultative approach throughout the entire test program. Lastly, our expert test engineers are in constant communication throughout the entire test process.

Summary of MIL-810 Humidity Regulatory Compliance

Generally, hot and humid climates are found in tropical areas. As mentioned above, humidity can also seasonally affect mid-latitude areas. Material in warm humid areas can experience high internal temperature and humidity conditions.

Humidity compliance testing introduces products to increasing levels of relative humidity to determine a product’s ability to operate in certain environments. Humidity testing will signal any design flaws that might lead to common issues such as: 

Changes to surfaces:

  • Oxidation and/or galvanic corrosion of metals
  • Increased chemical reactions
  • Chemical or electrochemical breakdown of organic and inorganic surface coatings
  • Interaction of surface moisture with deposits from external sources to produce a corrosive film
  • Changes in friction coefficients, resulting in binding or sticking

Changes to material properties:

  • Swelling of materials due to sorption effects
  • Other changes in properties
  • Loss of physical strength
  • Electrical and thermal insulating characteristics
  • Delamination of composite materials
  • Degradation of optical element image transmission quality
  • Degradation of lubricants

Effects of condensation and free water such as:

  • Electrical short circuits
  • Fogging of optical surfaces
  • Changes in thermal transfer characteristics

Humidity testing can be completed by using direct condensation and indirect effect. Direct condensation is the formation of water droplets on a device that can cause direct damage to susceptible components. The indirect effect can vary in form but generally involves moisture reaching sensitive components that cannot operate correctly in a moisture-filled environment.

Keystone’s Humidity Testing Capabilities and Equipment

Keystone Compliance operates state-of-the-art temperature and humidity test chambers. Our investment into our brand new drive-in chamber is a reflection of our years of testing experience.

Keystone Compliance offers temperature and temperature humidity testing in chambers ranging from small benchtop to large drive-in systems. Our walk-in chambers are designed to accommodate large equipment or packages. These chambers allow Keystone Compliance to be capable of moving, installing, and testing multiple rack assemblies. Currently, our largest chamber has dimensions of 12’x9’x10′ which is a volume of 1,080 cubic feet.

Our humidity testing lab also has the capabilities of building extensions off of the chambers to test even larger items. Keystone operates a large walk-in chamber that is specially equipped with twin 30 hp compressors and is capable of temperature transition rates exceeding 15 degrees Celsius per minute. All of Keystone’s test chambers operate with state-of-the-art digital temperature controllers. Every chamber is equipped with high and low-temperature safety devices.

Expert Regulatory Compliance Humidity Testing

Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. Our team strives to give our customers more time and energy on product development instead of testing. In addition to humidity testing, Keystone has a full scope of expertise including sand and dust, rain, fungus, and pyroshock.

We realize that temperature and temperature/humidity tests are the longest-running tests in your testing program, and we understand the importance of the reliability of environmental chambers.
