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
ISO image and Macintosh installations from a single disk image (by containing several file systems). An ISO can be "mounted" with suitable driver software, i.e. treated by the operating system as if it were a physical optical disc. Most Unix-based operating systems, including Linux and macOS, have built-in capability to mount an ISO. Versions of Windows after and including Windows 8 also have such capability. For other operating systems software drivers can be installed to achieve the same objective. Since there is no standard defining the ISO disc image file format, the term "ISO image" is sometimes used in a broader sense
