Positive Material Identification (PMI) is a non-destructive testing method that identifies material grade and alloy composition for quality control and material verification purposes. PMI is an integral part of both production and asset integrity management for industries including oil and gas, power, nuclear, aerospace and more.
Positive Material Identification Methods
Positive Material Identification is useful to ensure components are using the correct alloy and that the material conforms to customer and industrial standards and specifications. There are two different PMI techniques:
- X-ray Fluorescence (XRF) analyser: This is the most common method. It uses an XRF device that scans the metal material and identifies its key elements. However, it cannot detect carbon and some lighter elements and is not suitable for identification of pure carbon steel materials.
- Optical Emission Spectroscopy (OES): This positive material identification method can detect almost all types of elements including carbon and lighter elements and carbon steel.
