ANAB accreditation under ISO/IEC 17020 is the highest formal recognition an inspection body can earn in North America. It is the same standard that governs how Bureau Veritas, Intertek, and SGS operate their inspection divisions worldwide. When a solo independent inspector holds ANAB accreditation, it places them on the same institutional tier as billion-dollar multinational companies.
This article explains what ISO/IEC 17020 requires, what ANAB does as an accreditation body, how accreditation differs from certification, and what it means for clients who hire an accredited inspection body for their projects.
What Is ISO/IEC 17020?
ISO/IEC 17020:2012 is the international standard for the competence of inspection bodies. It was developed jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), and it is recognized by accreditation bodies in over 100 countries through the International Laboratory Accreditation Cooperation (ILAC) Mutual Recognition Arrangement.
The standard defines the requirements that inspection bodies must meet to demonstrate they are technically competent, organizationally impartial, and consistently performing inspections to documented methods. It covers five areas: impartiality and independence, personnel competence, inspection methods and procedures, quality management, and ongoing surveillance.
Unlike generic management system standards, ISO/IEC 17020 is specifically written for inspection work. It asks whether the body can actually perform accurate, unbiased inspections, not just whether it has paperwork in order.
ISO 9001 certifies a quality management system. ISO/IEC 17020 certifies the technical competence of an inspection body. They are not the same thing.
What Does ANAB Do?
ANAB (ANSI National Accreditation Board) is the primary accreditation body in the United States for testing, calibration, and inspection bodies. It is the US member of ILAC, the international cooperation body that links national accreditation systems worldwide.
When ANAB accredits an inspection body, it has conducted a formal assessment that includes reviewing all documented procedures, verifying personnel qualifications, examining inspection records, and witnessing actual inspections in the field. ANAB assessors are technical specialists, not administrative auditors. They evaluate whether the inspection body's people, methods, and systems meet the requirements of ISO/IEC 17020.
Accreditation must be maintained through annual surveillance assessments and periodic full reassessments. If deficiencies are found, ANAB can suspend or withdraw accreditation. There is no 'coast once certified' mechanism. The accreditation is active only as long as the body continues to meet all requirements.
Type A, Type B, and Type C Bodies
ISO/IEC 17020 defines three types of inspection bodies based on their independence from the parties involved:
| Type | Description | Example |
|---|---|---|
| Type A | Fully independent from the parties involved in design, manufacture, supply, installation, purchase, ownership, use, or maintenance of the items inspected | Third-party independent inspection company or consultant |
| Type B | Inspection department within a larger organization, separate from production but part of the same legal entity | In-house inspection department of a manufacturer |
| Type C | Inspection body that provides services to parties other than its parent organization but not exclusively third-party | Inspection arm of an industry association |
Norman QC operates as a Type A body, the most independent classification. Type A status requires structural separation from design, fabrication, and operational activities. The inspector has no financial or organizational interest in the outcome of the inspection other than performing it accurately.
What the Accreditation Process Requires
Achieving ANAB accreditation as an inspection body is not a short process. It requires building and demonstrating a functioning quality management system tailored to inspection activities. The key requirements include:
- -Impartiality documentation: Formal policies and procedures that identify and manage conflicts of interest. Personnel must declare any relationships that could compromise independence, and the inspection body must have mechanisms to address conflicts before they affect inspection work.
- -Personnel competence records: Education, training, experience, and ongoing performance records for all personnel performing inspections. ANAB verifies that credentials claimed are current and that personnel are assessed regularly.
- -Written inspection procedures: Documented inspection methods that reference the applicable codes and standards. Procedures must cover the scope of inspection being accredited and must be validated as adequate.
- -Equipment calibration and control: Calibration records for all measurement instruments used in inspection, with traceability to national standards. Instruments out of calibration must be removed from service immediately.
- -Internal audit program: Scheduled internal audits that evaluate whether the quality management system is functioning as designed, including inspection of actual inspection records.
- -Management review: Formal periodic review by management covering audit findings, client feedback, corrective actions, and system performance.
- -Corrective action system: A documented process for identifying non-conformances, determining root cause, and implementing corrections that prevent recurrence.
ANAB assessors then witness actual inspections to verify that field practice matches documented procedures. The assessment is rigorous. For a solo consultant to build, document, and sustain all of this represents a significant ongoing commitment beyond the inspection work itself.
How ILAC Recognition Works for International Projects
ANAB is a signatory to the ILAC Mutual Recognition Arrangement. This arrangement links accreditation bodies in over 100 countries. When an inspection body holds ANAB accreditation, its inspection reports are accepted by ILAC signatories globally without requiring separate re-verification of the inspector's qualifications or the inspection body's competence.
In practical terms, this means that inspection reports signed under a Norman QC ANAB-accredited scope are accepted in Saudi Arabia, the UAE, Australia, the UK, Singapore, and other ILAC member countries using the same standing that an Intertek or Bureau Veritas report would receive. The ILAC MRA is the reason major operators specify accredited inspection bodies for international procurement and fabrication work.
For operators sourcing equipment from fabricators in India, South Korea, China, or Europe, having an ANAB-accredited inspector conduct the source inspection means the reports satisfy both North American and international acceptance requirements without additional qualification steps.
Accreditation vs Certification vs Qualification
These three terms are frequently confused. They represent different levels of formal recognition:
| Term | What It Covers | Who Grants It |
|---|---|---|
| Accreditation | Formal recognition of the competence of an inspection body or laboratory to perform specific inspection activities | National accreditation body (ANAB in the US, UKAS in the UK, SCC in Canada) |
| Certification | Confirmation that a person meets the requirements of a certification scheme | Professional certification body (API, ASNT, AWS, BINDT, NACE/AMPP) |
| Qualification | Employer's or owner's determination that an individual is competent for a specific task | Employer, client, or operating company |
An inspector can hold multiple professional certifications (API 510, ASNT Level III, AWS SCWI) without their inspection body being accredited. Accreditation applies to the inspection body as a whole, encompassing its systems, personnel, procedures, and quality management. It is the highest level of formal recognition because it evaluates the entire operation, not just individual credentials.
What Accreditation Means for Clients
For clients specifying inspection services, ANAB accreditation under ISO/IEC 17020 provides three concrete benefits:
First, it reduces your audit burden. ANAB has already conducted a rigorous assessment of the inspection body's competence and systems. Clients who would otherwise need to audit their inspection provider before approving them can rely on the ANAB assessment in place of their own qualification audit. Major operators increasingly accept ANAB accreditation as satisfying their supplier qualification requirements for inspection services.
Second, it provides documented evidence of impartiality. The accreditation requires formal policies managing conflicts of interest, with ANAB oversight of those policies. If a dispute ever arises over an inspection finding, the accreditation provides a credible basis for demonstrating that the inspection was conducted without bias.
Third, it supports international report acceptance. Reports issued by ANAB-accredited inspection bodies are recognized by ILAC member countries without additional re-qualification steps. For projects involving fabricators, vendors, or regulatory bodies in multiple countries, this eliminates a significant administrative burden.
ANAB accreditation often functions as a binary qualifier: either the inspection body is accredited, or it cannot be approved for certain contract scopes. Access to these contracts is the primary commercial value of the accreditation.
How Rare Is ANAB Accreditation for an Independent Inspector?
Every ANAB-accredited inspection body in the oil and gas sector that can be identified in industry databases is a large company: Intertek, TUV Rheinland, Bureau Veritas, SGS, and similar multinationals employing hundreds to thousands of inspectors. The administrative infrastructure required to maintain accreditation, quality management documentation, internal audits, management reviews, calibration systems, and ANAB surveillance assessments, is normally handled by dedicated quality departments within those organizations.
For a solo independent consultant to achieve and maintain this accreditation requires building that infrastructure personally, in addition to performing inspection work. It is not common. It may be unique in the Canadian oil and gas inspection space for an individual practitioner.
Norman QC holds ANAB accreditation under ISO/IEC 17020 and maintains it through annual ANAB surveillance. The accreditation certificate and scope of accreditation are available for client verification.
FAQs
How do I verify that Norman QC is ANAB accredited?
ANAB maintains a public directory of accredited bodies. You can search the ANAB directory at anab.ansi.org and verify the current accreditation status, scope, and certificate independently. Norman QC can also provide the accreditation certificate directly upon request.
Does ANAB accreditation cover all inspection services?
ANAB accreditation is granted for a specific scope of inspection activities. The scope on the accreditation certificate defines exactly which inspection types and standards are covered by the accreditation. Work performed outside the accredited scope is not covered by the accreditation, though the inspector's personal credentials still apply.
Is ANAB accreditation the same as SCC accreditation in Canada?
ANAB (US) and SCC (Standards Council of Canada) are both ILAC signatories, meaning accreditation from either body carries the same ILAC MRA recognition internationally. They operate under the same international framework and mutual recognition applies between them.
Does accreditation mean the inspector never makes errors?
No. Accreditation means the inspection body has demonstrated systems, procedures, and competence at a level that satisfies ANAB's rigorous requirements. It significantly reduces the probability of systematic errors and provides a framework for identifying and correcting errors when they occur. It does not guarantee perfect results on every inspection.
