Positive Material Identification (PMI)

Introduction

Positive Material Identification (PMI) is a critical inspection method used to verify the chemical composition of metals and alloys to ensure compliance with engineering specifications, material standards, and design requirements. PMI is essential in industries where material mix‑ups can lead to catastrophic failures — including Oil & Gas, Petrochemical, Power Generation, Refining, Chemical Plants, Marine, Manufacturing, and Fabrication.

PMI is widely used for alloy verification, grade confirmation, corrosion‑resistant material checks, weld material validation, and in‑service inspection. Modern PMI technologies such as XRF (X‑Ray Fluorescence) and OES (Optical Emission Spectroscopy) provide fast, accurate, and non‑destructive material analysis.

This GTMCS Positive Material Identification (PMI) program provides comprehensive training in PMI principles, equipment operation, alloy identification, data interpretation, and compliance with international standards such as ASTM, API, ASME, ISO, and EN.
