(also referred to as MS81-2021 [General tolerance (machine cut)] ) is a specific technical standard used by the Mitsubishi Fuso Truck & Bus Corporation
to define general tolerances for linear and angular dimensions of machine-cut parts. Key Details of the Standard
: It provides permissible deviations for machining dimensions (typically less than 2000 mm) when specific tolerances are not indicated on a drawing by individual numerals or symbols. Context within Mitsubishi Fuso : It is an annex standard often cited alongside
, which is the overarching standard for drawing formats and general tolerances. Operational Rules New/Revised Drawings
: Drawings created after the enforcement of the latest standards follow a new classification system (classes f, m, or c). Old Drawings
: Drawings that followed previous internal tolerance classes (such as 1st class or 2nd class) are directed to follow Annex MS81-2021 Classification : In general, Class 1 tolerances
are the default standard within this annex unless otherwise specified. Accessing the Full Document

The MS81-2021 standard (formally Annex MS81-2021) is a technical specification from the Mitsubishi Fuso Truck & Bus Corporation that defines general tolerances for machine cut dimensions.
It is specifically used for "old drawings" that followed a 2-class system (1st class, 2nd class) rather than the newer f, m, and c classes introduced in standard MSF1-2021. Tolerance Table (Machine Cut) Ms81-2021 Standard Pdf
The standard specifies permissible deviations for linear dimensions up to 2000 mm when individual tolerances are not indicated on the drawing. Nominal Dimension (mm) 1st Class Tolerance (mm) 2nd Class Tolerance (mm) 6 and under ±0.1plus or minus 0.1 ±0.2plus or minus 0.2 Over 6 up to 30 ±0.2plus or minus 0.2 ±0.5plus or minus 0.5 Over 30 up to 120 ±0.3plus or minus 0.3 ±0.8plus or minus 0.8 Over 120 up to 315 ±0.5plus or minus 0.5 ±1.2plus or minus 1.2 Over 315 up to 1000 ±0.8plus or minus 0.8 ±2.0plus or minus 2.0 Key Application Details
Scope: Covers machining work for dimensions less than 2000 mm.
Default Use: In general, 1st class tolerances are used unless otherwise specified.
Drawing Indication: These tolerances are typically indicated in the title block of a drawing (per MSF1-1001) under a label like "TOLERANCES UNLESS SPECIFIED MACHINE CUT".
Evolution: Newer Mitsubishi Fuso drawings (made after the enforcement of MSF1-2021) now typically follow the f, m, or c class system similar to ISO 2768.
