JIS B 0024 is the Japanese Industrial Standard that defines the fundamental tolerancing principles

Why is JIS B 0024 Important?

1. Essential for Japanese Supply Chains: If your company manufactures parts for Japanese OEMs, your drawings must conform to JIS standards. Using a generic ISO or ANSI symbol for surface roughness can lead to rejection during PPAP (Production Part Approval Process).
2. Clarity and Unambiguity: The standard eliminates guesswork. For example, it clearly distinguishes between the required surface texture, the default texture, and the machining allowance.
3. Harmonizes with Global Standards: Because JIS B 0024 aligns with ISO 1302, it allows Japanese companies to trade globally without creating entirely unique drawing systems.
4. Prevents Functional Failure: Surface texture affects wear, lubrication, friction, coating adhesion, and sealing. JIS B 0024 ensures that the designer’s intent for these critical parameters is properly documented.

Size Control: Linear tolerances control only the actual local size (two-point measurement), not form deviations like circularity or flatness. JIS B 0024 is the Japanese Industrial Standard
