Dual-scheme inspector cert (ASNT + ISO 9712) for global mobility.
No outside consultant can certify your technicians — under ASNT SNT-TC-1A, certification is employer-based. An outsourced ASNT Level III does everything up to that line: authors the Written Practice, prepares and grades general, specific and practical examinations, approves NDT procedures, and provides multi-method technical oversight. The employer signs the certificate and holds the record.
NDT consulting engagements fall into five recurring problems. The programme problem: an inspection function that grew job by job and now faces a client audit with no coherent Written Practice and procedures of mixed parentage. The authority problem: work requiring an ASNT Level III signature — procedure approval, personnel qualification — with no Level III on staff. The interval problem: equipment on default inspection intervals that risk-based inspection to API 580 and API 581 would rationalise in both directions. The verdict problem: a finding needing an engineering disposition through fitness-for-service to API 579-1/ASME FFS-1 rather than an automatic repair. The build problem: a new facility or contract needing inspection capability designed before day one. Scope every engagement from the artefact produced at the end — an audit-ready Written Practice, an approved procedure set, an RBI programme a regulator accepts, or an FFS assessment carrying a signed run-or-repair decision.

What a contracted ASNT Level III can and cannot do — SNT-TC-1A versus ISO 9712
Activity
Contracted outside Level III (SNT-TC-1A / CP-189)
Third-party certification body (ISO 9712 / PCN / CSWIP)
Who holds the record
Author the Written Practice
Yes — drafted for the employer to review and adopt
Not applicable; the scheme document takes its place
Employer
Prepare and grade qualification examinations
Yes — general, specific and practical examinations
Body sets and administers its own central examinations
Employer / certification body
Approve NDT procedures
Yes — acting as the employer's designated Level III
Outside the scope of the certification scheme
Employer
Issue the certification itself
No — certification is an act of the employer and cannot be delegated
Yes — certificate issued to the individual, portable between employers
Employer / certification body
Near-vision and colour-contrast examination
Specifies the requirement; the employer arranges and records the examination
Required by the scheme before examination
Employer / certification body
Recertification decision and records retention
Advises and evaluates; cannot decide on the employer's behalf
Body manages renewal on its own published cycle
Employer / certification body
Under ASNT SNT-TC-1A certification is employer-based: the employer certifies its own personnel and cannot transfer that act to an agency, even when the agency performs all of the technical work. ISO 9712 inverts this — an accredited body certifies the individual, and the certificate travels with the person. This is the single most misunderstood boundary in Level III consulting.
Can we use an outside agency Level III instead of employing one?
Yes. SNT-TC-1A allows an employer to engage an outside agency ASNT Level III for the technical work — Written Practice authoring, examination preparation and grading, procedure approval and method oversight — provided the arrangement is documented in the employer's Written Practice. Responsibility for certifying personnel remains with the employer and does not transfer to the agency.
What responsibilities stay with the employer when the Level III is outsourced?
The employer adopts and maintains the Written Practice, holds training and documented experience records, arranges near-vision and colour-contrast examinations, issues the certificate, decides recertification, and retains the records for audit. A consultant produces and signs the technical work; the employer's name is on the certification. Auditors ask the employer, not the consultant, to produce that evidence.
How is ISO 9712 certification different from ASNT SNT-TC-1A?
SNT-TC-1A is a recommended practice for employer-based certification: the employer certifies its own personnel against its own Written Practice. ISO 9712 is third-party certification — an accredited certification body examines and certifies the individual, and the certificate travels with that person between employers. Many inspectors hold both: SNT-TC-1A for US work, ISO 9712 for international mobility.
When is fitness-for-service to API 579 the right answer instead of repair?
When a finding sits within a known damage mechanism and the real question is run, repair or re-rate rather than automatic replacement. API 579-1/ASME FFS-1 covers general and localised metal loss, pitting, blisters and HIC/SOHIC, crack-like flaws, creep and fire damage at Levels 1, 2 and 3. It needs the structured inspection record — thickness profiles and flaw dimensions — not a PDF.
How does risk-based inspection under API 580 and API 581 change intervals?
RBI replaces fixed intervals with intervals derived from probability and consequence of failure, mapped to credible damage mechanisms per API 571 and calibrated by inspection effectiveness. Intervals move in both directions — extending on low-consequence equipment, shortening where a mechanism is active and prior inspection was ineffective. What an auditor accepts is the documented basis, not the interval alone.
What is a Written Practice, and who is required to have one?
A Written Practice is the employer's own document describing how it trains, examines, qualifies and certifies NDT personnel: methods, levels, training hours, experience requirements, examination content, vision requirements, recertification and records retention. Under SNT-TC-1A every employer certifying its own NDT personnel needs one, and it is normally the first document a client or accreditation auditor requests.
What NDT consulting engagements actually look like
Most consulting enquiries arrive as one of five problems. The programme problem: an inspection function that grew job by job and now cannot pass the audit its biggest client just announced — no coherent Written Practice, procedures of mixed parentage, records scattered. The authority problem: work that requires an ASNT Level III signature — procedure approval, personnel qualification — with no Level III on staff. The interval problem: equipment running on default inspection intervals that a risk-based approach per API 580/581 would rationalise, in both directions. The verdict problem: a finding that needs an engineering disposition — fitness-for-service per API 579 — rather than an automatic repair. The build problem: a new facility, product line or contract that needs inspection capability designed before day one, not retrofitted after the first nonconformance.
How engagement works
Consulting is scoped from the artefact you need at the end: an audit-ready Written Practice, an approved procedure set, a qualified crew, an RBI programme with intervals a regulator will accept, an FFS assessment with a run/repair decision an engineer signed. We state what we will examine, what we will produce, and what remains your side — typically the operational records only you hold. Remote review handles most documentation work; site presence is reserved for what genuinely requires it, which keeps the engagement lean regardless of geography.
Choosing the right service line
If the trigger is an audit or a contract requirement, start with outsourced Level III services — the Written Practice and personnel qualification usually sit at the root. If the trigger is inspection cost or interval pressure, start with RBI programme design. If the trigger is a specific finding, go straight to fitness-for-service assessment. Unsure is also an answer — describe the situation and we will tell you plainly which of the five problems it is, including when the honest advice is that you do not need a consultant.
The consulting practice spans RBI programme design, fitness-for-service assessment under API 579, code consulting and procedure development. The single most requested engagement is different from all of them: acting as the named ASNT Level III for a company that does not employ one. That has its own page — NDT Level 3 consulting services — because the commitment, the deliverables and the audit exposure are unlike a project-scoped consulting job.
