Positive material identification (PMI) is the analysis of a material, this can be any material but is generally used for the analysis of metallic alloy to establish composition by reading the quantities by percentage of its constituent elements. Typical methods for PMI include X-ray fluorescence (XRF) and optical emission spectrometry (OES). [1]
Traceability and positive material identification (PMI) When the alloys for piping are forged, metallurgical tests are performed to determine material composition by % of each chemical element in the piping, and the results are recorded in a material test report, also known as a Mill Test Report (MTR).
Product and manufacturing information, also abbreviated PMI, conveys non-geometric attributes in 3D computer-aided design (CAD) and Collaborative Product Development systems necessary for manufacturing product components and assemblies. PMI may include geometric dimensions and tolerances, 3D annotation (text) and dimensions, surface finish, and ...
X-ray fluorescence. XRF scanning of the Rembrandt -painting Syndics of the Drapers' Guild. A handheld XRF analyzer gun. X-ray fluorescence ( XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
Nondestructive testing ( NDT) is any of a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. [1] The terms nondestructive examination ( NDE ), nondestructive inspection ( NDI ), and nondestructive evaluation ( NDE) are also commonly used ...
The main types are: Drug-drug interaction. This is when a medication reacts with one or more other drugs. For example, taking a cough medicine ( antitussive) and a drug to help you sleep (sedative ...
AGA – American Gas Association. AGRU – acid gas removal unit. AGT – (1) agitator, used in drilling. AGT – (2) authorised gas tester (certified by OPITTO) AGT – (3) Azerbaijan – Georgia – Turkey (a region rich in oil related activity) [3] AHBDF – along hole (depth) below Derrick floor. AHD – along hole depth.
Spark testing is a method of determining the general classification of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. [1] These sparks can be compared to a chart or to sparks from a known test sample to determine the classification.
