Course Description
PMI is the non-destructive analysis of a material’s elemental composition. It verifies that an alloy matches its specified grade or standard (e.g., 316L vs 304). PMI is a rapid screening tool, not a substitute for full mechanical testing.
What you'll learn in this course?
Define Positive Material Identification (PMI) and explain its critical role in materials engineering applications.
Identify at least three industrial scenarios where PMI is mandatory for safety and compliance.
Distinguish between the main PMI technologies (XRF, OES, LIBS) based on principle, advantages, and limitations.
Interpret a basic PMI test report and recognise common alloy grade discrepancies.
Apply best practices for sampling, surface preparation, and data recording to avoid false results.
Understand key industry standards governing PMI (API 578, ISO 17025, ASTM E1476).
Recognise the consequences of material mix-ups through real-world case studies.
