✦ Synopsis

Much of the performance data for nickel solutions is based on a British Standard (BS EN ISO 1462:1995) that grades the number of rust spots per square inch on the surface of the coating after accelerated exposure during a standard salt spray test. This has led to typical claims of 1000 h corrosion resistance for most nickel coatings.

However, Poeton's experience over several years appears to contradict this claim. Salt spray testing by the company shows that many materials rated to 1000 h would in fact show signs of corrosion after 40-50 h. The company is recommending that to maintain the confidence of the engineering community, the metal finishing industry needs to review its standards.
