When the "M" version (SI units) is specified, Annex A3 governs dimensional tolerances, not the values in brackets in the main text.

e.g., max deviation from flat surface per unit length depends on thickness and width.

因此，每當您使用上述任一產品標準時，實際上都在間接遵循ASTM A480/A480M的規範。 astm a480 a480m pdf

The dual designation (A480 and A480M) indicates that the standard accommodates two different systems of measurement:

Perhaps the most crucial aspect of the standard, A480 defines the acceptable variations in: Width Length Flatness Edge Camber When the "M" version (SI units) is specified,

⁠ASTM A480/A480M is the "Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip".

ASTM A480 acts as an umbrella regulation. When an engineer specifies a plate or sheet under other highly targeted material specifications, those standards explicitly inherit the rules laid out in A480. It applies to several major ASTM specifications including: ASTM A480 acts as an umbrella regulation

The primary purpose of ASTM A480/A480M is to provide a unified set of general requirements that apply to rolled steel plate, sheet, and strip under various ASTM product specifications. Unless otherwise specified in a purchase order or individual product specification, the requirements of this standard take effect.

Understanding this standard not only helps avoid costly non-compliance issues but also contributes to safer, more reliable products across the industries that rely on stainless steel flat-rolled materials every day.
