Introduction
The EN standards for stainless steel are quite complex and it is sometimes hard to know which standards you need to know about in order to fulfil all the requirements of an order. This article is an attempt to simplify the path through the maze of standards that now exists.
It is worth remembering that the following topics are usually covered in separate standards:
· Compositions and Properties
· Tolerances
· Test Methods
· Product Form Definitions
The logic of this approach is that a change to one aspect of a product does not lead to a change in all the others. However, it does mean that the user may have to follow a chain of references between standards. There are also some links to articles on this website dealing with the relevant standard
