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.
Count of the Saxon Shore Count of the Saxon Shore The Count of the Saxon Shore for Britain () was the head of the Saxon Shore military command of the later Roman Empire. The post was possibly created during the reign of Constantine I and was probably existent by AD 367 when Nectaridus is elliptically referred to as one by Ammianus.
