MIL-810 Salt Fog Regulatory Compliance Testing
Salt fog compliance testing evaluates the effectiveness of protective coatings and finishes on materials. This test type also determines the effects of salt deposits on the physical and electrical aspects of materials.
As a MIL-STD-810 certified lab, we realize the importance of salt fog regulatory compliance testing. Meeting the military 810 standard salt fog requirements can be difficult. We understand the challenges and guide companies through the process.
Keystone provides the peace of mind that all of your needs will be met. We have a reputation of helping customers achieve their MIL-STD product certifications. Furthermore, we are in constant communication throughout the entire test process. Keystone’s proven process helps avoid product launch delays.

Salt-Fog Testing Overview
Salt-fog testing, per MIL-STD 810 Method 509, determines the corrosion resistance of materials and impact of introducing a humid, salty solution on electrical components. Salt is one of the most persuasive chemical compounds in the world and is impossible to avoid. The worst salt fog effects occur in coastal regions. The effects of material to an environment where there is a corrosive atmosphere can be divided into three categories:
- Corrosion due to an electrochemical reaction.
- Accelerated stress corrosion.
- Formation of acidic/alkaline solutions following salt ionization in water.
- Impairment of electrical material due to salt deposits.
- Production of conductive coatings.
- Corrosion of insulating materials and metals.
- Clogging or binding of moving parts of mechanical components and assemblies.
- Blistering of paint as a result of electrolysis.
The most common coatings tested are steel, brass, and zamak. The salt-fog test essentially tests corrosion resistance through an accelerated process within a salt-fog chamber. The chamber controls the amount of salt-fog, concentration of salt, and pH. Different coatings have different behaviors and require different types of testing with varying durations.
Keystone’s Salt Fog Equipment and Capabilities
Keystone Compliance has a salt fog chamber that is one of the largest salt fog chambers manufactured. The chamber has internal dimensions of 8’ x 4’ x 4’. The chamber is capable of salt fog, mist, spray, and laden testing as described in the most popular test specifications.
Keystone customizes oversized chambers to accommodate much larger devices including cars, drones, and large pieces of machinery. If you have a large unit that is not suited to traditional chambers, we will work with you to find a solution that will get the job done.
