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.
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
