Keystone Compliance Humidity Testing Capabilities

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

Keystone’s 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.

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

Why is Humidity Regulatory Compliance Testing Important?

Humidity 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 humidity 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 the direct condensation and indirect effect.

Direct condensation is the formation of water droplets on a device that can cause direct damage to susceptible components. Indirect effect can vary in form but generally involves moisture reaching sensitive components that cannot operate correctly in a moisture-filled environment.

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.

Humidity Laboratory Compliance Testing Standards

  • ASTM A380 – 06: Standard Practice for Cleaning, Descaling, and Passivation of Stainless Steel Parts, Equipment, and Systems
  • ASTM D2247 – 11: Standard Practice for Testing Water Resistance of Coatings in 100% Relative Humidity
  • IEC 60068-2-30 Damp Heat: designed to determine the suitability of components, equipment or other articles for use, transportation and storage under conditions of high humidity – combined with cyclic temperature changes and, in general, producing condensation on the surface of the specimen.
  • MIL-STD-202 Method 103 : Evaluate the influence of moisture and moisture vapor on the materials used in components.
  • MIL-STD-810 Method 507 : Determines the ability to handle high humidity.
  • MIL-STD-883 Method 1013 : Detects the presence of moisture trapped inside the microelectronic device package. The most sensitive indicator of water ingress or liquid ingress is device leakage current.
  • SAE-AMS-STD-753: Corrosion-Resistant Steel Parts: Sampling, Inspection and Testing for Surface Passivation
  • RTCA/DO-160 Section 6: Provides an adequate test environment for equipment intended for installation in civil aircraft, non-civil transport aircraft and other classes, within environmentally controlled compartments of aircraft in which the severe humidity environment is not normally encountered.
