API ICP Self Study Notes API ICP Self Study Notes
Normally, the deviation of the pop pressure from the set pressure should not exceed; ±2 psi for pressure ≤ 70 psi ±3 % for pressure > 70psi [see ASME BPVC Section VIII, Division 1, Paragraph UG 134(d)(1)]. Within 0 % or +10 %. [see ASME BPVC Section VIII, Division 1, Paragraph UG 125(c)(3)]. Any allowance for hot setting should be made in accordance with the manufacturer's data. Any adjustment to the CDTP required to compensate for (1) in-service backpressure, (2) service temperature, or (3) test media should be made in accordance with the manufacturer's or user’s valve specification data.
