Application (pressure vessels, piping, structural, water), country of placement/usage (EN for most european things, ASME e.g. for pressure vessels in USA), and design code. The latter will typically involved the application, whereas country for usage may typically determine the design code (e.g. EN 13445 for european pressure vessels and ASME VIII-1 for american vessels). Jurisdiction can also dictate the required code.
