My question intent was to understand the logic behind initial statement posted quoting Desgin pressure =1.5 * Operating Pressure.
Apologies once again for any confusion caused.

You're getting things confused again. No code says any such thing.
And test pressure is not a design condition. Test pressures are a
consequence of the maximum allowable working pressure (MAWP). If you
want to talk about this stuff you really should use correct
terminology. Otherwise everyone just gets confused.
