Jis G 3193 Pdf [updated] -

For example, an engineer might specify a beam using the designation (defined in JIS G 3101), which dictates the steel must have a tensile strength of 400–510 MPa. However, if that engineer needs to know the exact thickness tolerance or the theoretical weight per meter of that SS400 plate, they must consult JIS G 3193 . This separation of duties—mechanical properties versus dimensional properties—is a hallmark of the JIS system and allows for greater flexibility in manufacturing.
