Flanges and their joints - Design rules for gasketed circular flange connections - Part 1: Calculation method

1.2 Requirement for use of the Calculation method
Where permitted, the Calculation method is an alternative to design validation by other means e.g.
- special testing;
- proven practice;
- use of standard flanges within permitted conditions.
