This European Standard for a single system of flanges specifies requirements for circular steel flanges in Class
designations Class 150 to Class 2 500 and nominal sizes from NPS ½ to NPS 24.
NOTE The relationship between nominal size (DN) and nominal size (NPS) is given for reference purposes in Tables 9
to 14.
This standard specifies the flange types and their facings, dimensions, tolerances, threading, bolt sizes, flange jointing
face surface finish, marking, materials and pressure/temperature ratings.
This standard does not apply to flanges made from bar stock by turning, or to flanges of types 11, 12, 13, 14 and
15 made from plate material.
