Training objectives

Surface replica training per ASTM E1351 and ISO 3274, for inspectors and QA. Intensive 1-day program — non-destructive technique for reproducing surface condition via polymer moulding, used in inspection, NDT, corrosion monitoring and in-situ ageing follow-up.

Typical applications: in-service weld-bead inspection, crack-growth monitoring, roughness characterization on non-removable parts, forensic engineering.

Detailed curriculum

Morning — Theory and preparation

Replica principle (acetate polymer, silicone), ASTM E1351 / ISO 3274 standards. Surface preparation (cleaning, release agent). Environmental conditions (temperature, humidity). In-situ inspection use cases.

Afternoon — Practice and certification

Replica execution on representative surfaces (weld, corrosion, roughness). Microscope / profilometer analysis. Replica traceability. Assessment + Kronos certificate.

Prerequisites

▸ Quality-control, NDT or inspection role
▸ Basic knowledge of surface metrology (Ra, Rz)
▸ Ability to work outdoors / at height (in-situ inspection)

Deliverables

▸ Kronos surface-replica certificate
▸ Replica procedure booklet (polymer selection, conditions, archiving)
▸ Standard replica traceability sheet

Frequently asked questions

Can replicas replace an in-situ profilometer?+

Partially. For point Ra/Rz measurements with long-term archiving, yes. For high-resolution 3D mapping, a direct profilometer is still preferable. Replicas excel when direct access is impossible.

Compatible with forensic engineering?+

Yes. The technique is recognized in materials and failure-analysis expertise. We cover the traceability aspects (chain of custody, timestamping, identification) required for litigation use.
