  2. Barcol hardness test - Wikipedia

    en.wikipedia.org/wiki/Barcol_hardness_test

    Barcol hardness is measured on a scale from 0 to 100 with the typical range being between 50B and 90B. A measurement of 60B is roughly equivalent to a Shore hardness of 80D or a Rockwell hardness M100. [4] [6] As defined in ASTM D 2583 the scale divisions from 0-100 should each indicate a depth of 0.0076 mm or the equivalent 0.0003 inches. [7]

  3. Rockwell hardness test - Wikipedia

    en.wikipedia.org/wiki/Rockwell_hardness_test

    A Rockwell hardness tester. The Rockwell hardness test is a hardness test based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]

  4. Shore durometer - Wikipedia

    en.wikipedia.org/wiki/Shore_durometer

    The term is also used to describe a material's rating on the scale, as in an object having a "'Shore durometer' of 90." The scale was defined by Albert Ferdinand Shore , who developed a suitable device to measure hardness in the 1920s.

  5. Blue Wool Scale - Wikipedia

    en.wikipedia.org/wiki/Blue_Wool_Scale

    A rating between 0 and 8 is awarded by identifying which one of the eight strips on the bluewool standard card has faded to the same extent as the sample under test. [ 4 ] [ 5 ] Zero denotes extremely poor colour fastness whilst a rating of eight is deemed not to have altered from the original and thus credited as being lightfast and permanent.

  6. List of body armor performance standards - Wikipedia

    en.wikipedia.org/wiki/List_of_body_armor...

    The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.

  7. Brinell hardness test - Wikipedia

    en.wikipedia.org/wiki/Brinell_hardness_test

    The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.

  8. Lightfastness - Wikipedia

    en.wikipedia.org/wiki/Lightfastness

    Simultaneously, another equivalent test strip set is exposed under a light source defined in the standard. For example, if the lightfastness of the colourant is indicated to be 5 on the Blue Wool scale, it can be expected to fade by a similar amount as the strip number 5 in the Blue Wool test strip set.

  9. Los Angeles abrasion test - Wikipedia

    en.wikipedia.org/wiki/Los_Angeles_abrasion_test

    In the 1930s, national studies demonstrated the Deval test did not correlate with the service record of sampled rock altogether, while an LA loss rating of less than 40% was a reliable indicator of quality. [9] The federal standard for LA abrasion testing was formally adopted by the ASTM in 1937. [10]
