What does third-party inspection involve?
Short answer
Third-party inspection is independent verification, by an agency the buyer appoints, that material meets the order before dispatch. It typically covers document review, visual and dimensional checks, PMI and witnessing of tests, and ends with an inspection release note and, where required, EN 10204 3.2 certification.
Scope
Typical TPI scope covers document review (MTCs, heat-treatment charts, NDT reports), visual and dimensional inspection, PMI, witness of mechanical or hydrostatic tests, marking verification and packing checks.
Planning
An inspection and test plan (ITP) defines hold and witness points. Share the ITP and the nominated agency with your order. Bright Tubes arranges inspection by the buyer-nominated agency and supports the inspector on site.
Outcomes
An inspection release note and, where specified, EN 10204 3.2 certificates countersigned by the inspector.
A typical inspection and test plan
- Document review: certificates, heat numbers, specification compliance
- Visual and dimensional inspection on a sample or 100%
- PMI on alloy materials
- Witness of hydrotest, NDE or mechanical tests where specified
- Marking and packing check
- Release note and certificate endorsement
Avoiding delays
Book the inspector early, share the order and specifications in advance, and agree hold points in writing. Missing documents are the usual cause of failed inspections. See EN 10204 3.1 vs 3.2.
