Summary of EIA 364-26 Salt Spray Compliance Testing

The salt spray EIA test method evaluates electrical connector components, finishes and mechanisms subjected to salt laden atmospheres. The test also permits electrical readings to be taken after exposure. Furthermore, this test assists in reproducing and replicating compliance lab testing procedures.

Test equipment used for EIA corrosion testing includes:

  • A chamber made of material which will not affect the corrosiveness of the fog.
  • Atomizers are used to produce a finely divided, wet, dense fog.
  • Air supply to humidify and warm the compressed air.
  • Salt solution concentration to keep the dry basis no more than 0.1 percent sodium iodide.

Data in this EIA test standard includes the title, date, time, and test engineer. Data may also include a sample description, test conditions and test equipment used. Photographs are necessary for proof of conformance. 

EIA 364-26 Compliance Testing Procedures

The test sample must be conditioned properly in order to conduct the salt spray test. A test sample consists of a connector assembly complete with wires, contacts, sealing plugs and accessories. This sample is suspended in a horizontal position.

Unless otherwise specified, the test specimen is handled as little as possible. Particularly on the significant surfaces. The specimen must also be prepared for the test immediately before exposure. When tested separately, connector contacts are mated or unmated and suspended horizontally as well.

The EIA test procedure is conducted at a temperature maintained around 95 degrees Fahrenheit. The apparatus is thoroughly insulated and preheated prior to atomization. Immersion heaters for maintaining the temperature in the chamber are prohibited.

Receptacles are fastened so that they are not shielded by samples. They are also done so that no drops of solution from the samples will be collected. Suitable atomization is obtained in boxes having a volume less than 12 cubic feet with the following conditions:

  • Nozzle pressure from 12 to 18 pounds per square inch.
  • Orifices from 0.02 to 0.03 inches in diameter.
  • 3 quarts of the solution per 10 cubic feet of boc volume per 24 hours.
