Positive Material Identification

Fast, Accurate Verification & Identification

Positive Material Identification or PMI Testing provides fast analysis of metal alloys through a non destructive method for material verification and identification. Laboratory Testing Inc. delivers highly reliable qualitative and/or semi-quantitative PMI Test results in Certified Test Reports to fit your requirements.

  • Analyzing composition to verify or identify materials
  • Identifying material grade
  • Confirming material conformance to specification
  • Verifying filler material in welding applications

PMI Inspection is an integral component of quality control and safety compliance for businesses in many industries. Alloys are specified for corrosion resistance, temperature tolerance or mechanical properties, and a material error can result in component failure.

The PMI method can be very helpful in selecting appropriate materials for your application, as well as in verifying that materials received are what you ordered. Material composition can be confirmed, or if unknown, we can provide a complete chemical breakdown of the material for identification. Material verification services will let you know if the tested material has a chemical composition consistent with its certification documents.
