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 the sizing operation can give dimensional accuracy to a portion of the part based on the contact with the die. Sizing is mostly used to give a forged or cast part better dimensional accuracy. Mated surfaces between touching parts like gears are often sized. The sizing operation also provides a better surface hardness and finish to the workpiece. Also, the sized surface of the workpiece gets denser and stronger when the operation is performed. The dimensional tolerance of the operation is about . Primary pressing or a compacting die are typically used when sizing small batches of compact. To keep
