RTCA DO-160 Section 14.0 Salt Fog Compliance Testing
The RTCA DO-160 salt fog test standard determines the effects of ocean conditions. These conditions are a salt atmosphere that can be extremely corrosive. Products placed in service on a plane operated near or over a salt water body of water are susceptible.
From an order of procedure standpoint, the salt fog test must always follow the fungus resistance test. It should also be stated that the salt fog test can have several different names. Names such as salt mist test and salt spray test are all essentially the same test.
What Does A Salt Atmosphere Do To Equipment?
Salt atmospheres can be highly corrosive. This corrosion can occur in a short period of exposure. The corrosion can clog or bind moving parts. This clogging is often the direct result of salt deposits. Insulation can break down and become ineffective.
Also, electrical components can be very susceptible to damage. For instance, wires and contacts can become faulty.

RTCA DO-160 Salt-Fog Test Equipment Categories:
The DO-160G Section 14 test standard specifies one category of equipment.
Equipment Category S:
Equipment installed in locations subjected to a corrosive atmosphere in the course of normal aircraft operations. Equipment meeting this description must go through RTCA-DO-160 salt spray testing.
Equipment Category T:
Equipment installed in locations where it is subjected to a severe salt atmosphere. This can include equipment exposed directly to external unfiltered air on hovering aircraft that may operate or be parked near the sea. Equipment meeting this description must go through RTCA-DO-160 salt mist testing.
What Equipment Is Needed to Conduct Salt Mist Testing?
A salt fog test lab like Keystone Compliance must have various pieces of equipment to complete the test. The main item is a salt spray chamber. The chamber has support racks and a reservoir for the salt solution. The chamber must have access to compressed air and nozzles. These are used to atomize the salt solution. The salt mist testing chamber must have a means of heating and controlling the chamber temperature. Also, the air must be humidified.

Modifications from one Version of RTCA DO-160 to the Next:
Changes from DO-160C Salt Mist Testing to DO-160D Salt Mist Testing
Change functional test criteria. Functional tests may now be performed following the 48-hour dry-out period.
Changes from DO-160D Salt Mist Testing to DO-160E Salt Mist Testing
Title of section was changed from Salt Spray to Salt Fog. Category T was added for severe salt atmosphere.
Changes from DO-160E Salt Mist Testing to DO-160F Salt Mist Testing
Changed term Salt Spray to Salt Fog throughout this section.
Changes from DO-160F Salt Mist Testing to DO-160G Salt Mist Testing
Add alternating periods of exposure and drying. Suppress the drying before power up for Category T.
