Shore durometer The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then read. The material under test should be a minimum of 6 mm (0.25 inches) thick. The ASTM D2240 standard recognizes twelve different durometer scales using combinations of specific spring forces and indentor configurations. These scales are properly referred to as durometer types; i.e., a durometer type is specifically designed to determine a specific scale, and the scale does not exist separately from the durometer.
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
