The most frequently cited references are ASME Section VIII Div. 1 (UG-125 to UG-138) and API Std 520/521 for petrochemicals. In Europe, EN ISO 4126-2 applies. For sanitary installations, ASME BPE and 3-A 616. The standards specify pressure tolerances (±5 %), lot testing, marking, operating/burst ratio requirements and inspection procedures.
