  2. Knoop hardness test - Wikipedia

    en.wikipedia.org/wiki/Knoop_hardness_test

    The test was developed by Frederick Knoop [2] and colleagues at the National Bureau of Standards (now NIST) of the United States in 1939, and is defined by the ASTM E384 standard. The advantages of the test are that only a very small sample of material is required, and that it is valid for a wide range of test forces.

    A diamond in the form of a square-based pyramid satisfied these conditions. It had been established that the ideal size of a Brinell impression was 3 ⁄ 8 of the ball diameter. As two tangents to the circle at the ends of a chord 3 d /8 long intersect at 136°, it was decided to use this as the included angle between plane faces of the ...
