    ASTM D5264 Standard Practice for Abrasion Resistance of Printed Materials by the Sutherland Rub Tester [13] ASTM D5963 Standard Test Method for Rubber Property—Abrasion Resistance (Rotary Drum Abrader) [14] ASTM D6279 Standard Test Method for Rub Abrasion Mar Resistance of High Gloss Coatings

  3. Martindale (unit) - Wikipedia

    en.wikipedia.org/wiki/Martindale_(unit)

    The Martindale method, also known as the Martindale rub test, simulates natural wear of a seat cover, in which the textile sample is rubbed against a standard abrasive surface with a specified force. The test equipment works in intervals of 5000 cycles, totalling the wear number (unit: Martindale) of abrasion cycles that leads to the material ...

  4. Four-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Four-point_flexural_test

    The test method for conducting the test usually involves a specified test fixture on a universal testing machine. Details of the test preparation, conditioning, and conduct affect the test results. The sample is placed on two supporting pins a set distance apart and two loading pins placed at an equal distance around the center.

  5. Los Angeles abrasion test - Wikipedia

    en.wikipedia.org/wiki/Los_Angeles_abrasion_test

    The test reports loss of mass to abrasion and impact, expressed as a percentage of initial sample mass. [7] Maximum acceptable loss for the base course of the road is 45%; the more demanding surface course must be 35% or less. [1] The test was developed by the city engineers of Los Angeles in the 1920s. [8]

    The test method for conducting the test usually involves a specified test fixture on a universal testing machine. Details of the test preparation, conditioning, and conduct affect the test results. The sample is placed on two supporting pins a set distance apart. Calculation of the flexural stress

  7. Tensile testing - Wikipedia

    en.wikipedia.org/wiki/Tensile_testing

    Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]

  9. Barcol hardness test - Wikipedia

    en.wikipedia.org/wiki/Barcol_hardness_test

    The Barcol hardness test is generally used on soft materials such as rigid plastics. It measures hardness based on indentation of a sharp point with a flat tip. The test is performed using a similar method and indentation device as that used to measure Shore D hardness, however the Shore D indentor has a round tip. [4]
