PMI (Positive Material Identification)
PMI (Positive Material Identification) testing is the analysis of materials to determine the chemical composition of a metal or alloy at particular (usually multiple) steps of alloy manufacturing or in-process alloy installation.
At INSCO fasteners we have the latest X - Ray Fluorescence (XRF) analysers which is one of the quickest and most comprehensive methods for Positive Material Identification where low level radiation is fired at the material and the energy levels reflected back from each element is measured, so identifying the alloy elements.
In using XRF, we can make Positive Material Identification. The data can be downloaded from the unit and saved for reference or creating reports. The data and NDT software of the analysers has to comply with FDA 21 CFR Part 11, which is a requirement for many of the customers.
The performance and capabilities of the XRF unit and a well laid procedure as per ASTM E 1476 procedure guarantee reliable and accurate results.
We use these machines in routine during in process testing and also during tests requirements from third party and visiting quality inspection agencies
We have the in-house capability to do tests for all materials covered under ASTM A 193 and A 194
