rigorous Inspection Processes
Incoming Inspections
Performed on raw materials or parts received from suppliers in accordance to ASTM E8,E18,E23 Or ISO 6892,6508,148:
- Visual inspection – for surface defects, corrosion, damage.
- Dimensional inspection – using calipers, micrometers, CMM, etc.
- Chemical composition analysis – via spectrometer or lab testing.
- Mechanical properties testing – hardness, tensile, impact, etc.
In Process Inspections
Carried out during manufacturing to catch defects early:
- First article inspection (FAI) – verifies first piece from production.
- Dimensional checks – to ensure tolerances are maintained acc. toISO 14253.
- Fit and alignment checks – especially in assemblies.
- Tool calibration checks – ensures measuring instruments are accurate.
- Statistical Process Control (SPC) – monitors process variation acc. to ISO 2859.
Final Inspections and Testing
Done before releasing the product in accordance to EN ISO 9712:
- Visual and dimensional inspection – verifies final specs.
- Non-Destructive Testing (NDT):
- Ultrasonic Testing (UT) acc. to ASTM E164
- Magnetic Particle Testing (MPT) acc. to ASTM E1444
- Dye Penetrant Testing (DPT)
- Radiographic Testing (RT)
- Destructive Testing (sample-based):
- Tensile, fatigue, impact, etc.
- Functional testing – checks if the component works as intended.
- Pressure or leak tests – for valves, pipes and assemblies.
Documentation and Certification
- Inspection reports
- Test certificates (e.g., Mill Test Certificate, MTC)
- Material traceability records acc. to ISO 1020
- Quality Control (QC) documentation
- 3.1/3.2 Certification
