New Cyclic Corrosion Test Cabinet for Salt Spray Exposure Testing

Rubber Consultants has recently acquired a 450-litre Cyclic Corrosion Test Cabinet (CCT Cabinet) that can test the tolerance of engineered products to salt-spray exposure.

These types of products, particularly those that are used in the underside of a vehicle, are often required to withstand 1000 hours of continuous exposure to salt spray at 35°C.

In the automotive industry, it is more common now to stipulate cyclic corrosion tests which involves periods of salt spray exposure, followed by air drying at an elevated temperature followed by exposure to high humidity. In other industries, such as in civil engineering, it is necessary to assess the durability of structural components exposed continuously to sea-mist. Corrosion testing is therefore specified in many product specifications.

The 450-litre CCT Cabinet has a pre-programmable function and a temperature range from ambient to 55°C. Rubber Consultants has assessed the performance of various materials in these aggressive environments, for example, the picture (bottom right) shows a mild-steel test piece and a nylon joint test piece after salt spray exposure testing. The test-piece geometry was developed at Rubber Consultants and TARRC during a EU funded project on “Environmentally Acceptable Bonding Methods for Rubber Based Engineering Components”. This test-geometry is now part of the ASTM standard; ASTM D 429 on bond durability testing.
