BS EN ISO 9227:2017

What is this standard about? It details the apparatus, reagents and procedures to be used in conducting neutral salt spray (NSS); acetic acid salt spray (AASS); and copper accelerated acetic acid salt spray (CASS) tests of metallic materials, with or without permanent or temporary corrosion protection. It also describes how to evaluate the corrosivity of the test cabinet environment. Who is this standard for?

Specifiers (architects and engineers) Laboratory personnel Purchasing management Quantity serveyors Quality and design engineers

The standard will typically be used in the following sectors:

Oil and gas Energy Construction Transport Aero Chemical Agricultural Street furniture Domestic building Local government

Why should you use this standard? It provides a systematic means of testing the corrosion resistance of metallic materials. It’s particularly useful for detecting discontinuities – such as pores and other defects – in certain metallic, organic, anodic oxide and conversion coatings. What’s changed since the last update? This standard replaces BS EN ISO 9227:2012. The key changes are a new section, new values for atomizing over pressure, a new specification on the treatment of test specimens and new recommendations.
