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.
On Shore and Sea On Shore and Sea On Shore and Sea is a "dramatic cantata" composed by Arthur Sullivan, with words by Tom Taylor. Sullivan completed this work to open the Royal Albert Hall, and it was performed at the opening of the London International Exhibition of art and industry on 1 May 1871. The concert featured works commissioned from Italy, France, Germany, and Great Britain. Charles Gounod was the French representative. The cantata has an appropriately international flavour, telling of war and reunion, based on a 16th-century conflict between Christians and Moors at a time when conflict raged between the Saracen settlements
