Quality Control and Testing Standards for Metallic Materials: ISO, ASTM, and Export Compliance
2026/07/03
1. Mechanical Testing
| Test Type | Key Standards | Parameters |
|---|---|---|
| Tensile Testing | ASTM E8, ISO 6892-1 | Yield/tensile strength, elongation |
| Hardness Testing | ASTM E10, E18, ISO 6507 | Brinell, Rockwell, Vickers hardness |
| Impact Testing | ASTM E23, ISO 148-1 | Charpy V-notch energy, transition temperature |
| Fatigue Testing | ASTM E466, ISO 1099 | Cyclic loading endurance limit |
2. Chemical Analysis Methods
- Optical Emission Spectroscopy (OES): Rapid analysis per ASTM E415/E1086.
- X-Ray Fluorescence (XRF): Non-destructive, portable PMI identification.
- Combustion Analysis (LECO): Carbon/sulfur ppm accuracy per ASTM E1019.
- ICP-OES: Trace element quantification for aerospace-grade materials.
3. Non-Destructive Testing (NDT)
- Ultrasonic Testing (UT): ASTM A435/A578 for plate lamination, ASME Section V for pressure vessels.
- Radiographic Testing (RT): ASTM E1742 for weld integrity.
- Magnetic Particle (MT): ASTM E1444 for ferromagnetic surface cracks.
- Liquid Penetrant (PT): ASTM E1417 for all non-porous materials.
4. Certification for Export
- Mill Test Certificate (EN 10204): Type 3.1 vs 3.2 — know which your customer requires.
- Material Test Reports (MTR): Heat number, composition, properties traceable to production lot.
- Third-Party Inspection: SGS, Bureau Veritas, TÜV, Intertek provide independent verification.
