Humidity Testing - Clark Testing

Humidity Testing



Humidity Testing falls under Clark’s broad scope of environmental testing capabilities. Variations in relative humidity cause environmental stresses on a range of products leading to issues such as corrosion, oxidation, electrical failure, swelling of materials, accelerated wear, brittleness, or granulation. These issues threaten the longevity or operation of components, necessitating humidity testing for the quality assurance process. With Clark’s large selection of environmental chambers, we can overlap humidity specifications with temperature, high altitude, and functionality testing among other disciplines.

Clark is a comprehensive resource for all environmental testing and commonly tests humidity to the following standards:

  • ASTM
  • MIL-STD-311
  • MIL-STD-810G
  • IEC-60068
  • MIL-STD-202
  • RTCA DO-160

With several environemtal chambers, Clark Testing has the ability to offer a unique set of testing capabilities. Below are some information about our chambers included temperature ranges, humidity ranges, and chamber sizes.
