This is an old topic discussed earlier . (thread292-225652: Hydrostatic Testing Safety)  Safe distance during hydrotesting.
The formula discussed was

safe distance = (0.15) x (D) x (a)^0.4 x (p)^0.6

where  D - internal diameter (m)
       a -  length / diameter of piece (m)
       p - test pressure  (bar)

The code reference given was Norwegian specification T0240|72-12| and in the footer "Rules, issue 96-02".

is it possible to know the title of the Norwegian Code which is referenced in earlier discussion?

A similar discussion on CR-4 FORUM
Gives reference to "Netherlands Stoomwezen Rules for pressure vessels


Would appreciate if anyone can clarify  the source of this formula for calculating safe distance during hydrotest.
Thanks in advance
