  2. Positive material identification - Wikipedia

    en.wikipedia.org/wiki/Positive_material...

    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]

  3. Product and manufacturing information - Wikipedia

    en.wikipedia.org/wiki/Product_and_manufacturing...

    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 ...

  4. Spark testing - Wikipedia

    en.wikipedia.org/wiki/Spark_testing

    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.

  5. Pipe (fluid conveyance) - Wikipedia

    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).

  6. Heat number - Wikipedia

    Heat number. An example of a heat number on a plate. A heat number is an identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill. Industry quality standards require materials to be tested at the manufacturer and the results of these tests be submitted through a report, also ...

  8. Magnetic particle inspection - Wikipedia

    en.wikipedia.org/wiki/Magnetic_particle_inspection

    The scale at the bottom is numbered in centimetres. Magnetic particle inspection ( MPI) is a nondestructive testing process where a magnetic field is used for detecting surface, and shallow subsurface, discontinuities in ferromagnetic materials. Examples of ferromagnetic materials include iron, nickel, cobalt, and some of their alloys.

  9. Nondestructive testing - Wikipedia

    en.wikipedia.org/wiki/Nondestructive_testing

    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 ...
