Gas Corrosion Tests
We perform endurance tests of the corrosive gas environment surrounding electronic parts, plated products, etc., and are equipped to examine four single or blended corrosive atmospheric gasses, SO2, H2S, NO2 and Cl2. In addition, by exposure of test objects to a dessicator of acid and alkaline solution we execute aeration tests for evaluation of corrosion.

Aeration Tests of Corrosive Gasses
Aeration test for evaluation of corrosion resistance is possible by adding acid or alkali solution in a dessicator and subsequent observation of ambient acid or alkali gas generation from the dessicator. In addition, aeration tests make it possible to investigate special ambient gasses around materials and products, such as a silicon gas aeration test which confirms contact failure as a result of ambient silicon gas in relays.

| Aeration Test Example | |
|---|---|
| Type of Gas | Purpose |
| Ammonia | Connector evaluation |
| Nitric acid | Gold-plating evaluation |
| Silicon | Relay contact evaluation |
Examinations of specific environmental pollutions with various chemicals and solutions such as commercially available hydrochloric acids and oxalic acids are possible as well.
