Positive Material Identification
Positive Material Identification is an analytical materials testing and materials identification technique used within the metal alloy industry which guarantees the materials chemical composition as required for quality control.
There are two globally accepted analytical methods for simple on-site Positive Material Identification: X-ray Fluorescence (XRF) and Optical Emission Spectroscopy (OES).
On-site PMI is done by using simple, portable analysers have a number of benefits. For example PMI testing can;
- ensure every part conforms to specification
- identify the correct alloy grade where a critical part is to be replaced
- facilitate inward goods inspection to ensure all materials received are to specification
Applied correctly, simple Positive Material Identification avoids any potential mix up, costly reworks, out of specification material used incorrectly. PMI testing avoids the failure of a critical component potentially leading, in the worst case, to a catastrophic failure of a process and loss of life.
