Hydraulic testing is the gold standard. According to R-001, the test pressure must be 1.3x the Maximum Allowable Working Pressure (MAWP) for at least 30 minutes. If the vessel leaks or yields, it fails. (Pneumatic testing is discouraged due to stored energy risks). | Aspect | NORSOK R-001 | ASME VIII
