When used as numbers, the letters are used in combination with the upper "keraia" numeral sign ⟨ʹ⟩ to denote numbers from 1 to 900 and in combination with the lower "keraia" ⟨͵⟩ to denote multiples
Cap torque tester variations can modify product characteristics with a result of different torque measurement. Cap torque tester The cap torque tester is used in the packaging industry to measure the opening or closuring torque of the screwing cap. It is a piece of specific quality control equipment that can be placed on the production line or in the laboratory. A torque tester is required during the packaging design process. It can be used as a destructive tester to identify if there is any material weakness of the packaging during the screwing process. It also allows one to define the torque tolerances of
