The (often referenced as MS81-2021 or MSF1-2021 Annex) is a critical manufacturing standard that defines general tolerances for machine-cut dimensions . Established primarily within major automotive and heavy machinery networks—including corporations like the Mitsubishi Fuso Truck & Bus Corporation —this standard streamlines technical product documentation by removing the need to specify individual tolerances for every single machined dimension.

The 2021 revision represents a significant modernization of older manufacturing philosophies. It replaces earlier iterations (such as MS 81-2012 or older "1st and 2nd class" systems) to better align with international benchmarks like ISO 22081 . This alignment is crucial for global supply chains, where a part designed in Japan might be manufactured in Malaysia or Europe. By adhering to MS 81:2021, Mitsubishi and its subsidiaries ensure that third-party contractors have a clear, standardized technical specification for machining, reducing waste from defective parts and improving "interoperability" across different production sites.

For standard linear features, the permissible deviation increases as the nominal size grows. This accounts for the natural tool deflection and thermal expansion encountered when machining larger workpieces.
