Shore durometer B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. Each scale results in a value between 0 and 100, with higher values indicating a harder material. Durometer, like many other hardness tests, measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material, its viscoelastic properties, the shape of the presser foot, and the duration of the test. ASTM D2240 durometers allows for a measurement of the initial hardness, or the indentation hardness after a given period of time.
4th Shore the 4th Shore - "Quarta Sponda" - because of the large community of Tunisian Italians living there. During less than thirty years (1912–1940) in Libya the Kingdom of Italy (in the territory that was called initially Italian North Africa (1912–1934) and later Italian Libya (1934–1940) or 4th Shore of Greater Italia) developed the cities and countryside with an enormous array of investments. They built huge public works, such as new town districts with streets and buildings, modern ports, the Italian Libya Railways, and long highways. The Libyan economy and trade flourished very much, similar to what happened during the ancient
