5.4 Design methods
5.4.1 General
Replace by:
This Part provides requirements for the design of pressure vessels or pressure vessel parts using design by
formulae (DBF):
In addition, two series of methods may be used to supplement or replace DBF:
a) methods based on design by analysis (DBA), namely Design by Analysis – Direct Route covered by
Annex B and Design by Analysis – Method based on Stress Categories, covered by Annex C;
b) methods based on experimental techniques.

Change the heading of 5.4.2:
5.4.2 Vessels of all testing groups, pressure loading of predominantly non-cyclic nature
Change the beginning of the first paragraph to:
The DBF requirements specified in clauses 7 to 16, annexes G and J, and the DBA requirements of Annex C
provide satisfactory …
