Inspection Services
Guardian Middle East LLC delivers third-party inspection services in Qatar under ISO/IEC 17020:2012 (Type A — third-party independent). Inspections cover welding, non-destructive testing (NDT), lifting equipment, pressure vessels, pipeline and piping, electrical installations, construction and civil works, and general third-party inspection. Inspections are issued under TNV Global Limited’s UAF-Accredited Inspection Body Certificate 5241222IB04 (valid 28 December 2024 – 27 December 2028). Guardian Middle East LLC is the local representative in Qatar (QFC Licence 03870). Absolute independence from inspected parties.
What Inspection Services Are
Inspection — under ISO/IEC 17020:2012 — is the examination of a product, process, service, installation, or design and the determination of its conformity with specific requirements or, on the basis of professional judgement, with general requirements. It is a distinct conformity assessment activity, separate from certification (ISO/IEC 17021-1) and from testing (ISO/IEC 17025), and serves a different purpose:
Activity | Purpose |
Certification | Confirms a management system or product conforms to a standard — issued by a certification body under ISO/IEC 17021-1 (management systems) or ISO/IEC 17065 (products). |
Inspection | Confirms a specific item, installation, or activity conforms to applicable requirements at a point in time — issued by an inspection body under ISO/IEC 17020. |
Testing | Determines characteristics of an item through laboratory analysis — issued by a testing laboratory under ISO/IEC 17025. |
Inspection is used in many sectors as a stand-alone activity (e.g., third-party witness inspection during construction) or as part of a broader compliance framework (e.g., periodic inspection of pressure vessels under regulatory regimes). Inspection results inform owners, operators, regulators, insurers, contractors, and end users about the actual condition or conformity of the inspected item.
Third-Party Independent (ISO/IEC 17020:2012)
Guardian’s inspection services operate as Type A — third-party independent. This is the highest impartiality classification under ISO/IEC 17020:2012. It is required for inspection that informs regulators, insurers, owners, and other third parties — and it carries the strongest credibility in tender contexts and supply-chain assurance.
ISO/IEC 17020:2012 Inspection Body Types
Type | Description |
Type A | Third-party independent. Provides inspection services to multiple parties; structurally independent of designers, manufacturers, suppliers, installers, owners, purchasers, and users of the items inspected. This is Guardian’s classification. |
Type B | In-house inspection providing services only to the parent organization. Not applicable to Guardian. |
Type C | Mixed — provides inspection services to its parent organization AND to other parties; subject to additional safeguards. Not applicable to Guardian. |
What Type A Means in Practice
- Independence from inspected parties — Guardian (and TNV Global Limited as the issuing inspection body) are not designers, manufacturers, suppliers, installers, owners, purchasers, or users of the items inspected.
- No commercial interest in the inspection outcome — fee structures are flat or scope-based, not contingent on whether inspection results are favourable to the inspected party.
- Documented impartiality framework — same family of safeguards as the certification impartiality framework (ISO/IEC 17021-1 §5.2 equivalent for inspection).
- Conflict of interest declarations — every inspector signs a declaration before each engagement covering financial interests, employment relationships, family connections, prior service relationships, and other potential conflicts.
- Cooling-off periods — inspectors with prior consulting, employment, or contractual relationships with the inspected party are excluded from inspecting that party for the cooling-off period.
- No consultancy — Guardian and TNV do not provide consultancy, design support, gap analysis, training, or implementation services to clients commissioning inspection.

Inspection Engagement Model
Inspection engagements follow a structured model aligned with ISO/IEC 17020:2012 §7 (Process requirements):
Step 1 — Inquiry & Scope Definition
- Client submits inquiry via process inquiry-and-quotation or directly to info@guardian.qa .
- Scope of inspection clarified — items installations activities to be inspected, applicable standards or codes, deliverables required.
- Quotation issued with fee structure, indicative timeline, and inspector competence profile.
Step 2 — Contract & Inspection Plan
- Inspection contract executed — incorporating these Terms of Service and engagement-specific provisions.
- CDD/EDD conducted under QFC AML/CFTR 2019 (same framework as certification engagements).
- Inspection plan agreed — scope, methods, codes/standards reference, sample size, location, timeline, inspector deployment.
- Conflict of interest declaration signed by deployed inspector(s).
Step 3 — On-site Inspection
- Inspector(s) arrive on-site at agreed schedule with required equipment and documentation.
- Inspection conducted per inspection plan and applicable code/standard requirements.
- In-process findings recorded; client representative may be present and may receive verbal briefing.
- On-site safety requirements respected — inspectors operate under client’s site safety regime augmented by their own safety competencies.
Step 4 — Inspection Report
- Inspection report issued under TNV Global Limited’s name and UAF-accredited mark.
- Report content per ISO/IEC 17020:2012 §7.4 — inspection identification, inspection body identity, items inspected, methods, results, statement of conformity / non-conformity, signatures.
- Report typically issued within agreed timeline post-inspection (commonly 5–10 business days; expedited timelines available on request).
Step 5 — Follow-up Activities (where applicable)
- Re-inspection following corrective action, where commissioned.
- Periodic / surveillance inspection on agreed schedule.
- Liaison with regulatory authorities or third parties relying on the inspection report.

Impartiality, Confidentiality & Non-Consultancy
Impartiality (ISO/IEC 17020:2012)
Inspection impartiality is required by ISO/IEC 17020:2012 §4.1 and is the structural foundation of Type A inspection. Guardian’s impartiality framework for inspection mirrors the certification impartiality framework — see legal Impartiality-statement — and includes:
- Identification and management of impartiality risks at engagement, periodic, and annual levels.
- Conflict of interest declarations signed by every deployed inspector.
- Cooling-off periods for inspectors with prior consulting, employment, or contractual relationships with the inspected party.
- Inspector rotation for clients in long-running engagements where over-familiarity could compromise objectivity.
- Independence of the inspection report sign-off function from on-site inspectors where required by the engagement.
Confidentiality (ISO/IEC 17020:2012)
Inspection findings are treated as confidential and shared only with the client and parties authorized by the client (or required by law / regulator). Guardian does not disclose inspection findings to competitors, regulators (except where statutorily required), or other third parties without client authorization.
Non-Consultancy (Absolute)
Guardian and TNV Global Limited do NOT provide consultancy, design support, gap analysis, training, or implementation services to clients commissioning inspection. Inspection is an independent third-party activity — providing design or remedial-action consultancy alongside inspection of the same item creates a self-review threat that compromises the inspection’s value.
Where clients identify nonconformities through inspection and need implementation support, they engage independent consultants outside the Guardian engagement. Guardian’s inspectors may explain WHAT a nonconformity is and WHY it is non-conforming against the standard — but will not propose specific remedial designs or supervise their implementation.

Frequently Asked Questions
Inspection reports are issued by TNV Global Limited under its UAF-Accredited Inspection Body Certificate 5241222IB04. Guardian Middle East LLC is the local representative in Qatar — your primary contractual counterparty. The inspection report bears TNV's name and UAF mark, with Guardian Middle East LLC's local-representative reference.
ISO/IEC 17020:2012 defines three types of inspection bodies. Type A is third-party independent — the inspection body is structurally independent of designers, manufacturers, suppliers, installers, owners, purchasers, and users of the items inspected. This is the highest impartiality classification under ISO/IEC 17020 and is required for inspection that informs regulators, insurers, and other third parties. Guardian's inspection services are Type A.
No. Inspection (ISO/IEC 17020) confirms that a specific item, installation, or activity conforms to applicable requirements at a point in time. Certification (ISO/IEC 17021-1 for management systems; ISO/IEC 17065 for products) confirms that a management system or product line conforms to a standard on an ongoing basis. The two are complementary but distinct conformity assessment activities.
No. Testing (ISO/IEC 17025) determines characteristics of an item through laboratory analysis. Inspection examines an item or activity and determines its conformity with specific or general requirements — typically without laboratory analysis. Some inspection activities use test results as inputs but do not themselves constitute testing.
Standards depend on scope. Welding: AWS, ASME IX, ISO 3834, ISO 9606. NDT: ASME V, ASNT, ISO 9712. Lifting: ASME B30, LOLER-equivalent. Pressure vessels: ASME VIII, API 510. Piping: ASME B31, API 570. Electrical: IEC 60364, IEC 61936. Construction: ACI 318, AISC 360, QCS. Project-specific codes are accommodated. Specific scope pages provide more detail.
Duration depends on scope, complexity, and inspection method. Simple inspections (e.g., single lifting equipment thorough examination) can be completed in a few hours. Complex inspections (e.g., multi-day pipeline integrity inspection) span days or weeks. The inspection plan agreed at Step 2 of the engagement model includes an indicative duration.
Yes — but with structural separation. Where the same client engages Guardian for both certification (via Guardian Assessment Pvt Ltd or TNV) and inspection (via TNV inspection body), the engagements are coordinated for client convenience but kept structurally separate to preserve impartiality. Different teams, different reports, different decision authority — same client experience.
No. Guardian and TNV operate under an absolute non-consultancy commitment. Our inspectors will identify and clearly explain a nonconformity and the standard it fails to meet — but will not design or specify remedial action. If you need implementation support after inspection, engage an independent consultant outside the Guardian engagement.
Yes. Inspection findings are confidential to the client and parties authorized by the client. We do not share inspection results with regulators, competitors, or other third parties without your authorization — except where required by law (regulator requests with proper authority, court orders). Confidentiality is required by ISO/IEC 17020:2012 §4.2.
Submit an inquiry via the standard inquiry form at /process/inquiry-and-quotation/ — selecting 'Inspection Services' as the engagement type and identifying the specific scope (welding, NDT, lifting, pressure vessels, pipeline, electrical, construction, or general third-party).
