In what order should the assignment decision be made?
Short answer: First define the job's method, sector and duty level; then verify the certificate scope and current status. If vision, continuity and job-specific conditions are complete, check the employer's written work authorization. If one of these links cannot be evidenced, do not complete the assignment.
An EN ISO 9712 certificate is important evidence of qualification; however, on its own it does not grant authorization to work in every NDT task. ISO 9712:2021defines the qualification and certification requirements for industrial non-destructive testing personnel by method. The current BINDT PCN24/GEN Issue 4 clearly distinguishes that central certification demonstrates general qualification, while authorization to work on behalf of the employer must be granted separately.
Seven check gates before assignment
A safe decision comes not from the existence of a PDF; it comes from the simultaneous match of the job requirement with verified personnel evidence. The sequence below catches a missing record early.
- Define the job: If the NDT method, product or industry sector, the requested duty and the role in the organization's procedure are not clear, personnel suitability cannot be evaluated.
- Verify the certificate identity: Record the person's name, certificate number, issuing organization, certification scheme and validity dates.
- Match the scope: Check whether the job's method, sector and required level are explicitly covered by the certificate. Do not accept similar-looking methods or sectors in place of each other.
- Confirm the current status: Do not look only at the uploaded copy; check via the issuing organization's online directory or official verification channel whether the certificate is valid, suspended, withdrawn or has a changed scope.
- Review vision and continuity records: Verify that the current vision requirements of the relevant certification scheme, the method/sector activity continuity and significant interruption rules are met.
- Complete job-specific conditions: If additional information or assessment is required for the organization's procedure, the customer specification, the equipment to be used, the acceptance criterion and safety training, link its evidence.
- Check the written authorization: If there is no current work authorization given by the employer for the defined duties, do not open the assignment even if the certificate is suitable.
This check deepens the personnel step in the broader NDT work order management flow. While the general work order also manages scope, instruments, field evidence and report closure, this guide focuses only on the person's suitability decision at the moment of assignment.
How is the certificate scope read?
Read the certificate with three separate questions: Which method? Which sector? Which level? The phrase “ISO 9712” in the certificate title does not replace these details.
| Check field | Need in the work order | Personnel evidence | Fail-closed result |
|---|---|---|---|
| Method | For example UT, MT, PT or VT | The same method in the certificate | If different or ambiguous, the assignment is closed |
| Sector | Product/industry scope | Sector scope in the document | If the scopes do not overlap, the assignment is closed |
| Level and duty | Performance, evaluation, instruction or approval role | Document level and organizational job description | If the role is not evidenced, the assignment is closed |
| Date and status | Planned/actual date of the job | Validity and official verification result | If expired or status is ambiguous, closed |
ISO's official page, ISO 9712:2021, 5th edition may be shown. A different publication year may appear on the cover in the European or national adoption. Therefore the system must store not only the standard number but the full standard as written on the certificate, the certification scheme and the issuing organization.
Why is a copy of the certificate alone not sufficient?
Because an uploaded file does not by itself prove the current status at the time of assignment or the issuing organization's valid scope. An official verification trace must also be obtained.
ASNT Certification Servicesstates that schemes and methods can be verified as current in the certificate holder directory. For another organization's certificate, that organization's official verification channel should also be used. If an accreditation claim in Türkiye is being evaluated, TÜRKAK's personnel certification accreditation statement and the current Accredited Organization Search record should be used to check the organization's relevant scope.
The assignment record can include the verification date, the official source used, the result, and the role that performed the verification. Do not copy unnecessary personal data; manage the minimum evidence needed for the decision, with access authorization and retention period.
How should vision and continuity records be handled?
Even if the certificate expiry date appears valid, the applicable scheme's vision and activity continuity requirements must be checked separately. An interruption or missing record must not turn into an automatic "suitable" result.
For example, the current PCN scheme PCN24/GEN Issue 4 and PCN24/CP16 Issue 3, treats records of vision evidence and continuity of activity in the method and sector as part of the certificate life cycle. Do not automatically carry the durations and evidence in this example over to other certification schemes; always open the current rules of the scheme the certificate belongs to.
In software terms, the correct model is dated records rather than a single "suitable/not suitable" checkbox: the type and date of the vision assessment, the continuity review, any declaration of significant interruption, the assessor and the supporting document. This way, when a record changes, it is visible which assignments need to be re-evaluated.
How are certificate and employer authorization distinguished?
The certificate is evidence of general competence within the certification scheme; authorization to work is an organizational decision about the person performing defined duties on behalf of the employer. Do not merge the two into a single date field.
BINDT PCN24/GEN requires the employer to issue written authorization, with a procedure defining job-specific training and assessment where needed. This distinction matters because the equipment used, organizational procedure, product, acceptance criteria or customer requirement can be more specific than the certificate examination. Additional performance demonstration may be required for safety-critical or specialized applications; ISO/TS 11774:2011 explains that performance-based qualification may be limited to specific procedures and applications, and the document was confirmed as current in 2023.
An in-house authorization record must clearly state the duties, method and sector limitation, start/end or review date, the underlying procedure, additional training/assessment and the approving authority. Personnel uploading their own record must not mean they approve their own assignment.
How to set up a fail-closed assignment rule in software?
The system should not guess suitability; it should compare the conditions approved by the organization through evidence fields and stop the assignment if there is a missing, expired or ambiguous link.
- The method, sector, task role and planned date are taken from the work order.
- Certificate scope, official status verification, vision, continuity and written authorization records are retrieved from the personnel card.
- Each rule produces a “pass”, “fail” or “evidence missing” outcome; missing evidence is not counted as suitable.
- If an exception is required, the justification, duration, risk assessment and independent approval are recorded; no silent pass-through is allowed.
- When certificate status, authorization or task scope changes, open jobs are placed in a re-evaluation queue.
the Vizyon NDT & DT solution in the pilot scenario, try examples of an out-of-scope method, a verification with an ambiguous validity period and a missing written authorization. Observe whether the system blocks assignment in all three situations, explains the reason and keeps the trace of the checks performed.

Assignment evidence to keep on a single screen
The assignment screen should summarize the evidence needed to decide, but should not replace the certification body or the technical authority.
- Work order method, sector, task and planned date
- Certificate number, full standard/program, issuing organization, method, sector and level
- Official status verification source, date and result
- Vision and activity continuity records according to the relevant scheme
- Significant interruption, suspension, scope change or restriction information
- Job-specific training/assessment and safety conditions
- The employer's written work authorization, its scope and the approving role
- The result of the assignment decision, its justification and the immutable audit trail
