Repair Straddling the 2025 Edition Effective Date
A repair organization is replacing a 36 in. longitudinal shell section on an ASME Section VIII Division 1 air receiver. The vessel has a MAWP of 200 psig, a 48 in. inside diameter, and National Board number 76,301. The repair procedure was written and qualified under the NBIC 2023 edition, which the jurisdiction has adopted. The jurisdiction has also published that the NBIC 2025 edition takes effect January 1, 2026. The shop plans to begin cutting on December 15, 2025, and to complete welding, post-weld heat treatment, and nondestructive examination by January 10, 2026. The 2025 edition is a new edition with revised Part 3 text, and the AIS has not yet completed a gap analysis between the shop's 2023 procedure and the 2025 requirements. The shop wants to keep its 2023-qualified procedure and submit the R-1 after January 1. The AIS must decide which edition governs the repair, whether the procedure must be re-qualified, and how to avoid a registration rejection.
1. Which NBIC edition governs the repair, and how should the AIS handle the work that spans the effective date?
Read the worked answer
The starting point is the edition adopted by the jurisdiction and in effect when the repair work is performed. The repair begins December 15 under the 2023 edition, but welding, post-weld heat treatment, and nondestructive examination extend past the January 1, 2026 effective date. The AIS should request written transition guidance from the jurisdiction before work starts. If the jurisdiction has no transition rule, the conservative approach is to treat work performed on or after January 1 as subject to the 2025 edition and to document the split. The repair organization cannot choose the edition by delaying the R-1; the data report follows the work, not the filing date. A single repair spanning editions needs a written plan approved by the Authorized Inspection Agency and accepted by the jurisdiction. The AIS should also verify that the repair organization's authorization and the AI's commission remain valid throughout the work.
2. Must the 2023-qualified repair procedure be re-qualified under the 2025 edition?
Read the worked answer
Do not automatically re-qualify, and do not automatically accept. The AIS should perform a documented gap analysis between the 2023 procedure and the 2025 Part 3 requirements. If the 2025 text changes an essential variable, such as procedure qualification, post-weld heat treatment, nondestructive examination, or AI review hold points, the procedure must be revised and re-qualified before the affected work. If the change is only documentation or review, a procedure revision and AI review may suffice. Because the jurisdiction's adoption notice is the legal trigger, the AIS should confirm whether the jurisdiction has adopted any transition or grace period. If the 2025 text is ambiguous, request a National Board interpretation rather than making an undocumented field decision. The gap analysis, the procedure revision, and the AI's approval should be retained in the job file.
3. What should the R-1 show about the code edition, and what registration steps reduce the risk of rejection?
Read the worked answer
The R-1 should identify the code edition that actually governed the repair. If the repair straddles editions, attach a narrative that identifies which work was performed under which edition and the jurisdiction's transition approval. Use the data report form edition required by the jurisdiction at the time of registration. The AI's signature must be dated when the AI actually verified the work, with a valid commission. Submit only after completion and after the AI has verified post-weld heat treatment and nondestructive examination. Registration is a record; it does not retroactively approve a repair performed to the wrong edition. If the National Board rejects the report, correct the technical record, do not merely resubmit the same form. The AIS should also confirm that the repair organization has the correct authorization and that the fee and attachments are complete.
