Vendor inspection in Turkey
Vendor Inspection Services in Turkey for Industrial Equipment
When equipment is being manufactured at a Turkish supplier, the buyer may need visibility before fabrication is complete or the equipment is dispatched.
Dilenza provides independent project-specific inspection support at manufacturers, fabrication facilities, assembly workshops and other supplier locations in Turkey.
The assignment can follow the client's:
- Inspection and Test Plan
- Purchase order
- Technical specification
- Approved drawings
- Manufacturing and test procedures
- Applicable project standards
Inspection can cover one defined manufacturing milestone or continue through several stages of production.
The agreed scope establishes what the inspector is expected to review, witness, measure and report.
This page covers supplier inspection in Turkey. For broader country coverage, see third-party inspection services in Turkey; for worldwide assignments, see our vendor inspection services.
Inspection scope
What Can a Vendor Inspector Check?
Vendor inspection is planned around the equipment and the project's controlled documents.
- Stage 1
Project Documentation
Review the documents relevant to the assigned inspection stage. These may include the ITP, drawings, purchase order, manufacturing procedures and previous inspection findings.
- Stage 2
Materials and Traceability
Check material identification, markings, certificates and traceability records where included in the agreed scope.
- Stage 3
Manufacturing and Fabrication
Attend defined manufacturing, fabrication, machining or assembly activities.
Depending on the assignment, checks may include fit-up, workmanship, dimensions, equipment identification and manufacturing status.
- Stage 4
Hold and Witness Points
Attend project-defined hold points and witness points.
The ITP and project procedures establish the notification process and what action is required before work proceeds.
- Stage 5
Testing and FAT
Witness specified tests or factory acceptance testing according to the approved procedure and the inspector's assigned responsibilities.
The agreed scope must distinguish between tests performed by the supplier or laboratory and activities witnessed by the inspector.
- Stage 6
Final Inspection and Documentation
Perform the agreed final checks and review the specified documentation before the project's release or shipment stage.
The inspector reports findings against the agreed requirements. Final acceptance remains with the responsible project parties unless a specific authority has been explicitly assigned.

FAT & testing
Factory Acceptance Test Witnessing in Turkey
A Factory Acceptance Test may be an important inspection point before equipment leaves the manufacturer.
Dilenza can review requests for an inspector to attend defined FAT activities at a Turkish supplier.
Depending on the approved test procedure and agreed responsibilities, the inspector may:
- 1Review the FAT scope and relevant procedure
- 2Verify equipment identification
- 3Witness specified functional or performance tests
- 4Record relevant results and observations
- 5Review the supplier's test records
- 6Report deviations or outstanding points
The supplier or designated testing party performs the test unless the project explicitly assigns otherwise. The inspector's responsibilities and acceptance criteria must be defined before attendance.
Inspector selection
The Right Vendor Inspector for Your Equipment
A vendor inspector should be selected for the actual equipment and inspection responsibilities—not simply because the supplier is nearby.
Where a project includes specialist welding or coating activities, Dilenza can review whether the requirement calls for one appropriately qualified professional or separate specialist inspectors.
Relevant inspector profiles can be shared for client technical assessment before the assignment is confirmed.
Dilenza reviews:
- Equipment type and manufacturing process
- Required inspection discipline
- Applicable standards and client specifications
- ITP points and tests to be witnessed
- Relevant equipment and industry experience
- Project-required qualifications or approvals
- Supplier location, working language and access conditions
- Schedule, duration and reporting requirements
Standards & requirements
Project Standards and Client Requirements
The applicable requirements depend on the equipment, purchase order, project specification and assigned inspection scope.
Depending on the project, documents may reference:
- ASME or API requirements
- EN and ISO standards
- AWS standards
- Client and end-user specifications
- Approved drawings and manufacturing procedures
- Inspection and Test Plans
- Test procedures and reporting requirements
Where a project specifies an inspector qualification, client approval or designation, that requirement must be reviewed against the controlled project documents.
The applicable standard, edition, inspection points, acceptance criteria and inspector responsibilities must come from the controlled project documentation.

What Will You Receive After the Inspection?
Reporting depends on the agreed scope and the client's reporting format.
A vendor inspection report may include:
- Supplier, location and inspection date
- Equipment and manufacturing stage
- Inspection activities performed or witnessed
- ITP and document references
- Measurements and test observations, where included
- Deviations or issues requiring attention
- Status of previously identified points
- Photographs, where permitted and included in scope
- Outstanding items and relevant follow-up information
The report gives the project team a record of what was inspected and observed. It does not replace the supplier's quality-control responsibilities or the buyer's final acceptance decision.

FAQ
Vendor Inspection in Turkey — Frequently Asked Questions
What is vendor inspection in Turkey?
Vendor inspection is independent technical inspection at a Turkish manufacturer or supplier against the agreed project requirements.
It may take place during manufacturing, fabrication, assembly, testing or final inspection.
Can Dilenza inspect equipment at a Turkish supplier?
Yes. Dilenza can review requirements at Turkish manufacturers, fabricators and supplier facilities, subject to the equipment, inspection scope, location, schedule and suitable inspector availability.
Can an inspector attend an ITP hold point or witness point?
Yes. The request should identify the relevant ITP point, activity, supplier, required date and inspector responsibilities.
The project's ITP and procedures determine the applicable notification and hold-point arrangements.
Can Dilenza witness a factory acceptance test in Turkey?
Yes. FAT witnessing can be reviewed where the equipment, approved test procedure, acceptance criteria, location and schedule are defined.
The supplier or designated testing party performs the test unless the agreed scope states otherwise.
Can Dilenza provide recurring or resident vendor inspection?
Yes. Recurring visits or resident inspection can be considered according to the manufacturing programme, required presence, equipment and suitable inspector availability.
Can one inspector attend for a single visit?
A single visit can be requested for an ITP point, test, FAT, repair verification or final inspection, subject to the technical scope, location, schedule and suitable inspector availability.
Can vendor inspection include welding or coating?
Yes. Welding or coating activities may form part of a vendor-inspection scope.
Where specialist inspection or a specific qualification is required, Dilenza reviews whether an appropriately qualified specialist is needed.
Is vendor inspection the same as a supplier audit?
Not necessarily. Vendor inspection generally focuses on specific equipment and project-defined manufacturing activities.
A supplier audit typically assesses the supplier's systems, processes or capabilities. Confirm the required service when submitting the enquiry.
Does the inspector approve equipment for shipment?
The inspector reports according to the agreed responsibilities. Release or acceptance authority must not be assumed; it must be explicitly defined by the project.
Does Dilenza replace a statutory or notified-body inspection?
No. Dilenza's normal vendor-inspection role is independent project inspection against the agreed scope.
Where statutory inspection, certification or legally required conformity assessment applies, the responsible authorised party must be identified separately.
What documents should I send?
Send the available ITP, purchase order, specification, drawings, test procedure, supplier location and expected dates. If some details are not yet available, explain what is known in the request.
