PMI Testing

XRF Material Verification – Fast, Accurate, Certified
At Berkeley Stainless Fittings Limited, material integrity is non-negotiable. To ensure we receive exactly what we order from our suppliers, we’ve invested in advanced positive material identification (PMI) technology—specifically, the Vanta L XRF Analyzer from Olympus, purchased in 2019.

After appointing a certified Radiation Protection Advisor and completing two days of intensive training, our team is fully qualified to operate the unit safely and effectively. This allows us to verify stainless steel grades with confidence—ensuring the material delivered matches the specification required.

Key Benefits of Our XRF Analyzer:

  • Rapid results: Material composition is identified within seconds
  • High throughput: Dozens of items can be tested in the time it takes for a single moly drop test
  • Non-destructive testing: No damage to the material being inspected
  • Grade assurance: Confirms alloy content and grade before fabrication begins

Testing Services Available:
We also offer a PMI testing service - you can send us your material, and we’ll perform XRF analysis and provide full certification of the results. This is ideal for manufacturers, installers, and fabricators who need documented verification for compliance, traceability, or peace of mind.

Whether you're validating incoming stock, checking legacy components, or preparing for a regulated installation, our XRF capabilities ensure you’re working with the right material - every time.
