Salt Spray Testing - Clark Testing

Salt Spray Testing

Clark Testing’s salt spray test induces corrosion of resistant materials and surface coatings. These tests often fall under environmental aging or equipment qualification to ensure that components under test can withstand intense or prolonged environmental stresses over accelerated life duration.

Many factors affect the corrosion of the test material. Metallic finishes or corrosion-resistant coatings are commonly used on equipment that undergo salt spray testing. The material as well as the duration of test may affect the oxidation of equipment. These factors are determined by a variety of standards; ASTM-B117 is the most common, although Clark also tests to MIL-STD-810, ISO-9227, and RTCA DO-160 standards.


  • ASTM-B117
  • MIL-STD-810
  • ISO-9227

The testing chamber provides a controlled corrosive environment where a salt water solution is atomized by means of spray nozzles using pressurized air. This produces an environment of dense salt water fog, so that test samples exposed to this environment are subjected to severely corrosive conditions.

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.
