ASTM B117 duration - real time correlation

Q. Good morning I write to you from Italy as I work for a research & development laboratory and I would like to know the correlation between the duration of an ASTM B117 test and the real life of our products(range hoods). Than you very much.

A. Juri - There is no direct correlation between hours in salt spray and real life. The salt spray test is best used as a process control tool. B117 is very specific about this several times throughout the document.

A. Hi Juri,

The short answer to your question is that there is no correlation between results from a salt spray test and real-world performance of your product.

Other accelerated tests have been proposed, but there is no consensus about whether these tests have better correlation than that provided by B-117.
