flange ratings and hydro testing
(OP)
When hydrotesting a piping spool with say 6 inch 150 pound flanges, is there a safety factor built into the flanges and piping that would allow testing to take place above 150 pounds. If so what is the safety factor and where would I be able to reference this in an applicable code?

It the upper left hand part of the chart the Box says
"Hydrostatic Test Pressure (PSIG)". That should answer your question.

"2.6 System Hydrostatic Testing
Flanged joints and flanged fittings may be subjected
to system hydrostatic tests at a pressure of 1.5 times the
38°C (100°F) rating rounded off to the next higher 1 bar
(25 psi) increment. Testing at any higher pressure is the responsibility of the user, taking into account the
requirements of the applicable code or regulation."
for piping you should review the applicable code
