MS 81:2021 is the Malaysian Standard specifically covering the requirements for the production and use of ready-mixed concrete. It serves as the primary technical benchmark for the construction industry in Malaysia to ensure the quality, durability, and consistency of concrete delivered to sites. Key Aspects of MS 81:2021
Quality Control: Defines the stringent processes required for batching, mixing, and transporting concrete to maintain its specified properties (such as workability and strength).
Material Standards: Specifies the types of cement, aggregates, water, and admixtures that are permissible for use in concrete production.
Compliance and Testing: Outlines the mandatory testing procedures, including slump tests and compressive strength tests, that must be performed to verify the concrete meets design specifications.
Certification: Frequently used by the Construction Industry Development Board (CIDB) and SIRIM QAS International as the basis for certifying ready-mixed concrete plants. Why It Matters
This standard is critical for engineers, contractors, and developers in Malaysia. Adhering to MS 81:2021 minimizes the risk of structural failures and ensures that the materials used in infrastructure projects—from high-rises to bridges—are of a verified, high quality. Accessing the PDF

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)
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.
