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.

Clark Highlights


Seismic OSHPD Testing

California’s Office of Statewide Health Planning & Development requires products to pass unique and intense seismic testing under ICC Evaluation Service acceptance criteria. Due to the state’s geology, the OSHPD requires that tests be performed according to soil class and seismic profile. We tested the above 9,000 lb., 15(l) x 5(w) x 12.5(h) ft. unit for soil class D at an SDS level of 2.50, translating to an AFLX-Horizontal level of 3.2 g and -Vertical level of 1.68g. The table can generate up to 5g on units weighing 2,000 lbs. and has an overall capacity of 20,000 lbs., making it one of the largest triaxial seismic tables in the world.
