EIA 364-26 Salt Spray Tester For Electrical Connectors
The EIA 364-26 salt spray test method is used to assess the effects of a controlled salt spray environment on electrical connector components, surface coatings, and structures. This method allows the measurement and evaluation of electrical properties after exposure under specific conditions.
Unless otherwise specified, test samples should be handled as little as possible. Especially on important surfaces. Samples must also be prepared for testing immediately before exposure. When tested separately, the connector contacts are also paired or disconnected and suspended horizontally.
EIA test procedure tests should be performed at a temperature of 35°C +1°C, -2°C(95°F +2°F, -3°F) in the exposed area. Satisfactory methods for precise temperature control include locating the equipment in a room where the temperature is properly controlled, thoroughly insulating the equipment and preheating the air to the proper temperature before atomizing, and wrapping the equipment and controlling the temperature of the water or air used. Do not use immersion heaters to maintain the temperature in the chamber.
The container is secured so as not to be blocked by the sample. This is also done so as not to collect droplets of solution in the sample. In boxes less than 12 cubic feet in volume, a suitable atomization effect can be achieved under the following conditions:

Summary of salt spray test
Salt spray testing, in which a sample is placed in a fine mist of salt solution, has more or less several useful purposes when the inadequacies and limitations of salt spray testing are fully recognized. There is no implied relationship between this test and the effects of the coastal atmosphere, and its use is limited to comparing the corrosion resistance of various materials and protective coatings. The damage mechanism caused by salt spray is electrolytic corrosion.Test equipment
The chamber and all accessories should be made of corrosive materials that will not affect the fog, such as glass, hard rubber or plastic. Wood or plywood should not be used because they are resins. Materials containing formaldehyde or phenol should not be used. In addition, all parts in contact with the sample should be made of materials that do not cause electrolytic corrosion. The laboratory and accessories shall be constructed and arranged so that the spray of all samples can circulate freely to the same extent, the liquid in contact with the test sample cannot be returned to the salt solution storage tank, and the spray or condensate droplets on the sample cannot be directly impacted. The chamber should be properly ventilated to prevent pressure buildup and allow for an even distribution of salt spray. The exhaust end of the exhaust port should prevent strong air flow so as not to produce strong air flow in the chamber.
Test procedure
The test sample must be properly adjusted before the salt spray test can be performed. The test sample consists of a connector assembly that includes wires, contacts, sealing plugs, and fittings. The sample is suspended in a horizontal position.Unless otherwise specified, test samples should be handled as little as possible. Especially on important surfaces. Samples must also be prepared for testing immediately before exposure. When tested separately, the connector contacts are also paired or disconnected and suspended horizontally.

The container is secured so as not to be blocked by the sample. This is also done so as not to collect droplets of solution in the sample. In boxes less than 12 cubic feet in volume, a suitable atomization effect can be achieved under 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.
JOEO salt spray tester
The JOEO salt spray tester is suitable for salt spray corrosion testing of components, components, electrical and electronic components as well as protective coatings of metal materials and industrial products to assess their corrosion resistance. The device complies with several test standards, including ASTM B117, ISO 9227, MIL-STD 202, JIS Z 2371, MIL-STD 810G, and EIA 364-26, and is capable of simultaneously testing temperature, humidity, and salt spray.If you want to know more about salt spray testing, feel free to contact our engineers who will provide you with detailed technical support and answers.
