Surveillance Audit Service in Turkey

At QCmatic, we provide comprehensive Surveillance Audit Services in Turkey to help international buyers, manufacturers, and project owners ensure that products, processes, suppliers, and management systems remain compliant, consistent, and continuously improved over time.

Unlike a one-time inspection, a surveillance audit is a repetitive, ongoing quality assurance tool. It verifies that previously certified or approved processes remain under control, suppliers continue to comply with requirements, and products maintain the same level of quality batch after batch.

Our experienced auditors perform independent, third-party surveillance audits that give you confidence in your suppliers, reduce risks of non-conforming products, and safeguard your reputation in global markets.

Types of Surveillance Audits We Provide

1. Process Surveillance Audits

• Continuous monitoring of production lines, assembly processes, and machining operations.
• Verification that CNC machining, casting, welding, painting, heat treatment, coating, or assembly operations remain within approved parameters.
• Identification of risks like process drift, operator deviations, or equipment miscalibration.

2. Product Surveillance Audits

• Regular checks on finished or semi-finished goods.
• Verification of dimensions, tolerances, surface finishes, welding seams, heat treatment results, coatings, and packaging quality.
• Ensures that products match customer specifications, drawings, and contractual requirements.

3. Compliance Surveillance Audits
