Ms812021 Standard Pdf Jun 2026
: The Japanese Industrial Standard for general machining tolerances shares an identical framework with MS81-2021, dictating identical ±0.1plus or minus 0.1 ±0.2plus or minus 0.2 bounds for small-scale turned or milled items.
It ensures that whether a part is made in Japan, Thailand, or the US, the "General Dimension Tolerances" are identical.
parts. This standard specifies permissible deviations for linear and angular dimensions on machining parts of less than 2,000 mm. You can find related technical drawings and manual updates for these standards on platforms like Malaysian Standard (MS EN 81:2021 series)
