Do you feel, well, rusty when it comes to determine what kind of rust you're facing? Don't worry, now there's a new edition of The Rust Grade Book (SS-EN ISO 8501-1:2007). The standard contains twenty-nine reference photographs representative of different rust grades and preparation grades which are used to specify the quality of surface preparation. To make it easier for you, we have also published a new guide on how to interpret the standard.
