  2. Oil analysis - Wikipedia

    en.wikipedia.org/wiki/Oil_analysis

    Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process.

  3. Alkali–silica reaction - Wikipedia

    en.wikipedia.org/wiki/Alkali–silica_reaction

    The mechanical stresses induced by the thermal cycles create micro-cracks in the concrete matrix and so facilitate the accessibility to water of the reactive mineral phases in the treated samples. [48] The concrete microbar test was proposed by Grattan-Bellew et al. (2003) as a universal accelerated test for alkali-aggregate reaction. [49]

  4. Spectrometric Oil Analysis Program - Wikipedia

    en.wikipedia.org/wiki/Spectrometric_Oil_Analysis...

    Spectrometric Oil Analysis Program (SOAP) is a method used by aircraft operators, including several Air Forces of the World, to test the health of aircraft engines by performing frequent laboratory testing of the engine oil. The tests reveal the chemical composition of any metal particles suspended in the oil samples. By comparing the results ...

  5. Triaxial shear test - Wikipedia

    en.wikipedia.org/wiki/Triaxial_shear_test

    During the test the pore pressures of fluids (e.g., water, oil) or gasses in the sample may be measured using Bishop's pore pressure apparatus. From the triaxial test data, it is possible to extract fundamental material parameters about the sample, including its angle of shearing resistance, apparent cohesion, and dilatancy angle.

  6. Peroxide value - Wikipedia

    en.wikipedia.org/wiki/Peroxide_value

    The peroxide value is defined as the amount of peroxide oxygen per 1 kilogram of fat or oil. Traditionally this was expressed in units of milliequivalents, although in SI units the appropriate option would be in millimoles per kilogram (N.B. 1 milliequivalents = 0.5 millimole; because 1 mEq of O2 =1 mmol/2 of O2 =0.5 mmol of O2, where 2 is valence).

  9. Crude oil assay - Wikipedia

    en.wikipedia.org/wiki/Crude_oil_assay

    The results of crude oil assay testing provide extensive detailed hydrocarbon analysis data for refiners, oil traders and producers. Assay data help refineries determine if a crude oil feedstock is compatible for a particular petroleum refinery or if the crude oil could cause yield, quality, production, environmental and other problems.
