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.
Shore skink species. Shore skink The shore skink ("Oligosoma smithi" ), also commonly known as the short-tailed skink, Smith's ground skink, Smith's moco, and Smith's skink, is a species of skink native to the north half of the North Island of New Zealand. The shore skink is always found near the shoreline and prefers open areas such as around driftwood at the high tide mark. "Oligosoma smithi" eats insects and probably anything that moves and fits in its mouth. The shore skink is diurnal (active during the day) and spends most of its time hunting or basking in the sun.
