The Rejected-Report Checklist: Six Fields Reviewers Look For First
Inspection reports get rejected for six recurring defects: no procedure identification and revision, an unidentified calibration block or reference standard, no technician certification reference, a location description that cannot be re-found, acceptance criteria not stated, and results not tied to those criteria. ASME Section V makes most of these mandatory record content, not formatting preference.
A rejected inspection report costs more than the re-issue. The equipment stays isolated, the weld stays unaccepted, and the next survey window closes while a reviewer waits for a field that should have been on the form. ASME Boiler and Pressure Vessel Code Section V treats report content as mandatory: Article 4 requires the procedure identification and revision, the instrument serial number, the search unit serial number, frequency and size, the beam angles, the couplant brand or type, and the cable type and length for every ultrasonic examination. Article 7 requires the examination personnel identity and, where the referencing code section calls for it, the qualification level, plus the date and time the examination was performed. Article 2 requires a radiograph review form listing each radiograph location and naming the representative who performed final acceptance. A report missing those fields does not fail on style. It fails the code.

| Rejection trigger | What the reviewer cannot do | Code basis | Field that closes it |
|---|---|---|---|
| Procedure not identified by number and revision | Confirm the examination followed a qualified, current set of instructions | ASME V T-493 (UT); T-793(a) (MT) | Procedure number plus revision letter and approval date, in the header block |
| Calibration block or reference standard unnamed | Reproduce the sensitivity setting or verify the reference reflector | ASME V T-492 equipment records; referencing code section | Block ID, material, thickness range, reflector geometry, calibration status and due date |
| No technician certification reference | Establish the examiner was certified to the method and level on the work date | ASME V T-793(d); ASNT SNT-TC-1A employer certification records | Name, method, level, written practice reference, certification and vision expiry dates |
| Location described in prose, not coordinates | Return to the same spot for repair verification or the next interval | ASME V T-491 (type, location, extent); T-292 radiograph locations | Datum, weld or component ID, station along a stated convention, offset and direction |
| Acceptance criteria not stated on the report | Know which standard and edition the call was made against | API 510: the inspector evaluates and accepts NDE results to the acceptance criteria | Code, edition, clause and table quoted on the report itself |
| Results not compared to the stated criteria | See how each indication was judged accept or reject, and by whom | ASME V T-292 evaluation and disposition, plus identification of the accepting representative and date | Per-indication row: measured dimension, criterion limit, disposition, evaluator, date |
A Returned Report Is a Schedule Event, Not a Paperwork Event
The rejection email arrives three days after the crew demobilised. A reviewer at the client, the authorised inspector, or the attending surveyor has read the package and found a field missing. The examination itself was sound: the weld was scanned, the indication was sized, the call was correct. None of that survives, because the document carrying the result cannot be verified against anything. The report goes back, the technician who performed the work is on another job in another state, and the equipment stays isolated while a form gets corrected.
Nobody line-items this cost. It surfaces as a schedule slip on the turnaround, an extra attendance day on the class survey, or a second mobilisation that nobody quoted. The contractor absorbs the rework hours and the owner absorbs the downtime, so neither party's cost system attributes the loss to the report format. That accounting gap is precisely why the same handful of defects recurs across the industry, contract after contract, without anyone treating the format as the root cause.
Six defects recur: the procedure is not identified by number and revision, the calibration block has no identity, nothing ties the result to a certified person, the location cannot be found again, the acceptance criteria are absent, and the results are never compared to those criteria. Each has a named source in code. None requires judgment to fix. All six are template problems, which makes them solvable once rather than argued about on every job.
Defect One: The Procedure Has No Number and No Revision
ASME Boiler and Pressure Vessel Code Section V, Article 4, paragraph T-493 requires the procedure identification and revision to be recorded for each ultrasonic examination. Article 7, paragraph T-793 opens with the same requirement for magnetic particle work. The revision is not decoration. It is the only thing connecting the result on the page to a specific, approved set of instructions covering scan plan, sensitivity, surface condition and evaluation level.
A reviewer who sees UT-01 with no revision letter cannot establish whether the technician worked to Revision 3, approved last quarter, or Revision 2, superseded because the calibration sequence changed. The reviewer has one defensible response, which is to return the report. Getting this right costs one field on the header block and a controlled procedure list that the written practice already obliges the contractor to maintain and a qualified ASNT Level III to approve.
Defect Two: The Calibration Block Has No Identity
ASME Section V paragraph T-492 requires the ultrasonic instrument identification including the manufacturer's serial number, the search unit identification including serial number, frequency and size, the beam angles used, the couplant brand name or type, and the search unit cable type and length. Contractors record the instrument and stop there. The reference standard the sensitivity was actually established on goes unnamed, and with it the entire basis of the measurement.
Sensitivity has no meaning apart from the reflector it was set on. A report stating 80% full screen height from a side-drilled hole is uninterpretable without the block identification, the material, the thickness, the hole diameter and depth, and the block's own calibration status. Record the block ID and its certificate reference alongside the instrument serials, and a reviewer can reproduce the setup two years later during a fitness-for-service assessment.
Defect Three: Nothing Ties the Result to a Certified Person
ASME Section V paragraph T-793 requires the examination personnel identity for magnetic particle examinations and, where the referencing code section calls for it, the qualification level. That is the code floor. The commercial floor sits higher, because the reviewer needs to establish that the named person held a current certification in the method, at the level the scope required, on the date the work was actually performed.
ASNT Recommended Practice No. SNT-TC-1A places certification with the employer. The employer prepares the written practice, the employer's Level III approves it, and the certification record carries the printed legal name and signature of the designated Level III who verified the candidate's qualifications. A report that names a technician without pointing at that record leaves a reviewer holding a name and nothing else.
In-service work adds a second layer. Under API 510 the examiner performs the nondestructive examination and does not evaluate the results against the code unless specifically trained and authorised by the owner-operator, while the inspector evaluates and accepts the results and makes the fitness-for-service recommendation. Two roles, two names, two signature blocks. Collapsing them into one line reading Inspected By invites the exact question the report exists to answer.
Defect Four: The Location Cannot Be Found Again
Paragraph T-491 requires the type, location and extent of every rejectable indication, and directs that non-rejectable indications be recorded as the referencing code section specifies. Slag near the north end satisfies none of that. A location description passes when a second technician, holding only the report and a tape measure, can put a probe on the same square centimetre of metal on a different day.
That means a fixed datum, the weld or component identification, a distance along a stated direction convention, an offset from the weld centreline, and a sketch or model reference. Owners running a digital twin of the asset get this for free, because the indication is pinned to a coordinate on the model rather than described in prose. Repair verification, remaining-life calculation and the next inspection interval all depend on returning to the same spot.
Defect Five: The Acceptance Criteria Are Not on the Page
A thickness reading without a criterion is a number. An indication length without a criterion is an observation. Neither is an inspection result, and a reviewer who has to go and find the governing clause before the report means anything will send it back rather than do the contractor's work for them. State the code, the edition, the clause and the table, quoted on the report itself, next to the result they govern.
Edition control matters as much as the clause number. The contract invokes a specific edition and addenda, and acceptance limits move between editions. A report citing a code without the year forces the reviewer to guess which set of limits was applied, and guessing is the one thing a quality record exists to eliminate. Print the edition and the addenda date in the header, and the ambiguity disappears permanently.
Defect Six: The Results Do Not Meet the Criteria on the Page
Stating the criteria in one section and the results in another leaves the comparison to the reader. Paragraph T-292 requires the radiograph review form to carry the evaluation and disposition of the materials or welds examined, the identification of the representative who performed final acceptance, and the date of that evaluation. The comparison is the deliverable, not an implication the reviewer is expected to draw unaided.
Build it as a per-indication row: indication identifier, type, location, measured dimension, the criterion limit that applies, the disposition, and the person who made the call. A reader scanning that table sees exactly how each judgment was reached and can audit any single line. A reader scanning a paragraph of prose followed by a bare ACCEPT stamp sees an assertion, and assertions get returned.
What a Compliant Report Carries, Front to Back
Header block: client, asset and component identification, work order, procedure number and revision, code and edition with the acceptance clause named, examination date and shift, location or drawing reference, and the surface condition and stage of manufacture or service. This block answers what was examined, under whose instructions, and against which limits. Populate it first and six of the common rejection triggers are already closed.
Technique block: instrument make, model and serial number, search unit or yoke or source details with serial numbers, couplant or consumable batch designations, calibration block or reference standard identification with its calibration status, beam angles or exposure parameters, cable type and length, and the lighting equipment where the method requires it. This block answers whether an independent party can reproduce the result.
Results and disposition block: the per-indication table, the acceptance decision against the stated criterion, the technician's name, level, certification reference and vision currency, the reviewer or Level III who evaluated the results, and the dated signatures of both. This block answers who is accountable for the call. Three blocks, populated every time, and the six defects have nowhere left to appear.
Format Is a Code Requirement, and Templates Beat Discipline
The argument that report layout is house style survives only until somebody reads the record paragraphs. ASME Section V does not describe a preferred appearance; it lists fields that shall be recorded. Article 2 mandates documented technique details and a radiograph review form. Article 4 mandates procedure identification and revision plus the equipment records. Article 6 mandates penetrant, remover, emulsifier and developer designations, the indication map, material and thickness, and the lighting equipment. Article 7 mandates personnel identity and the date and time.
Relying on technicians to remember a dozen mandatory fields at the end of a twelve-hour shift is a control that fails at exactly the moment it is needed. A structured capture form that refuses submission until every mandated field carries a value converts the code requirement into a property of the system. The same data record then drives the client's template, the internal quality file and the ERP job record without a second transcription, which is also where most of the report turnaround time hides.
Contractors who have collected several rejections in a row have a systemic problem in the written practice, the procedure set, or the report template, usually all three at once. A structured NDT programme audit and gap assessment finds the missing fields against the codes the contracts actually invoke, before a client or a surveyor finds them. Owners sitting on the other side of this conversation should read the contractor vetting checklist and ask for a sample report before award.
Which ASME Section V paragraph requires the procedure revision on the report?
ASME BPVC Section V, Article 4, paragraph T-493 requires procedure identification and revision to be recorded for each ultrasonic examination. Article 7, paragraph T-793 imposes the same requirement on magnetic particle examinations, alongside equipment type, current type, particle type, personnel identity and the date and time the examination was performed. The referencing code section can add fields on top.
What has to appear on a UT report about the equipment used?
ASME Section V paragraph T-492 requires the ultrasonic instrument identification including the manufacturer's serial number, the search unit identification including serial number, frequency and size, the beam angles used, the couplant brand name or type, and the search unit cable type and length. Omitting the serial numbers breaks traceability between the reading and a calibrated instrument.
How should an indication location be written so it survives review?
Give a fixed datum, the weld or component identification, a distance along a stated direction convention, and an offset from the weld centreline. ASME Section V paragraph T-491 requires the type, location and extent of every rejectable indication. A location that a second technician cannot reach with a tape measure and the report alone will not pass a repair-verification review.
Does the report need to name the technician and the certification level?
ASME Section V paragraph T-793 requires the examination personnel identity for magnetic particle work, plus the qualification level where the referencing code section calls for it. Beyond the code minimum, name, method, level, the written practice the certification was issued under, and the certification and vision expiry dates let a reviewer confirm currency without emailing the contractor.
What does a radiographic package have to carry that a UT report does not?
ASME Section V paragraph T-291 requires documented technique details: source or focal spot size, base material type and thickness, weld thickness and reinforcement, minimum source-to-object distance, source-side-to-film distance, film manufacturer and designation, number of films per cassette, and single or double wall exposure and viewing. Paragraph T-292 adds a radiograph review form naming the representative who performed final acceptance.
Who is allowed to evaluate the results on an in-service inspection report?
Under API 510 the examiner performs the nondestructive examination and does not evaluate results against the code unless specifically trained and authorised by the owner-operator. The inspector evaluates and accepts NDE results and makes the fitness-for-service recommendation. A report that records readings without identifying who evaluated them leaves that decision unattributed, and reviewers return it.
