Frequently Asked Questions
There is extensive real-world reliability data, and it’s one of the strongest differentiators of our equipment.
Our chambers are used daily in our accredited corrosion lab, running harsh OEM cyclic tests like GMW 14872 and Ford L-467.
Many customers—including Toyota, Honda, Tesla, Magna, ZF, Denso, Valeo, Bosch, Boeing, and numerous Tier-1 suppliers—run our chambers 24/7.
A significant portion of our installed base has been in service 15–25 years with only routine PM. Legacy Harshaw units from the ’80s and ’90s still operate after simple refurbishment.
The salt spray test (ASTM B117, ISO 9227) exposes materials to a controlled salt fog. It is the most widely recognized accelerated corrosion test.
In the context of ASTM B117, the terms are interchangeable and refer to the same continuous spray environment.
ASTM B117 defines the equipment, solution, temperature, and exposure conditions for valid corrosion testing.
Automotive, aerospace, marine, military, coatings, and industrial labs rely on salt fog chambers for corrosion durability testing.
Typical exposures range from 24–96 hours for coatings screening to more than 1,000 hours for qualification work.
