This section encompasses methods of Positive Material Identification (PMI) Testing, a non-destructive method of identifying the chemical composition of alloys and metals quickly.

PMI is useful in confirming material compositions. Using this data, it is possible to specify component properties based on the material it is made from.

Typical methods of PMI include Optical Emission Spectrometry (OES) and X-ray Fluorescence (XRF).
