Shoe size technical specification from International Standards Organisation. It contains three conversion tables (for adults and children) which feature major shoe sizing systems (e.g., Mondopoint, United States, European, United Kingdom, China, and Japan). Each table is based on actual foot length measurement (insole) in millimeters; typical last length ranges are also included. The standard includes conversion tables for Mondopoint (USSR/Russian/Chinese/Japanese/Korean systems) using length steps of 5 mm and 7.5 mm, European Paris point system, and UK 1/3 inch system. The standard has also been adopted as Russian GOST R 57425-2017. The standard is maintained by ISO/TC 137, which also developed ISO/TS 19408:2015
Cold sizing an elastomer ring into the lower die in order to compensate the elastic die deflection. Cold sizing Cold sizing is a squeezing operation performed at temperatures significantly below the melting point to finish the surface of a workpiece to ensure better dimensional accuracy and surface finish. The sizing operation is a squeezing operation that minimizes the thickness of the metal. Sizing is performed in an open die and only the surface where the die and workpiece touch will be sized. Many ferrous metal castings are sized to sharpen corners and flatten holes around piercings. Sizing pressure is determined by area
