The supplier shipped plates that were technically compliant with the old standard but out of spec for the new contract. Because the PDF on the engineer's desk was wrong, they rejected a $200,000 shipment.
Using a standardized reference like JIS G3193 ensures consistency across the global supply chain.

If you manage to obtain the PDF, you will find it divided into clear sections. Here is what you need to look for:
: It ensures that a "10mm plate" purchased from different Japanese mills will have the same thickness tolerance.
The standard, titled "Dimensions, mass and permissible variations of hot rolled steel plates, sheets and strips," is a technical specification published by the Japanese Standards Association (JSA) . It serves as the primary reference for ensuring dimensional accuracy and tolerance compliance in the Japanese steel industry. Overview of JIS G3193 The supplier shipped plates that were technically compliant
A standard "JIS G3193 PDF" typically includes detailed tables and rules for the following:
: Rules for measuring how "straight" or "flat" a sheet must be. This is critical for automated fabrication processes like laser cutting or robotic welding.
The primary objectives of the JIS G 3193:2025 revision were to: | Thickness range (mm) | Width < 1,600
Numerical values and rounding practices follow to prevent discrepancy disputes between steel manufacturers and buyers during factory acceptance testing. Jis G3193-2005 | PDF - Scribd
Measured at any point not less than 25 mm from the edge for mill-edged strips, or 15 mm for cut-edged products.
JIS G 3193 covers hot-rolled products produced either by reversing mills (such as heavy quarto plates) or continuous rolling mills (such as wide coils and cut sheets). The specific product categories mentioned in a JIS G 3193 PDF Overview include:
