What is the PN rating of a flat flange?

For instance, a Flat Flange Pn 16 is designed to operate in pressures up to 16 bar. Typically ratings include the following PN Flange Dimensions i.e. – PN6, PN10, PN16, PN25, PN40, PN64 as well as PN100. The American ANSI standard generally refers to the PN instead to a pressure / temperature rating, which in turn has been termed as Class.
