The most frequently consulted part of the standard is the table for thickness tolerances. The allowable deviation from a nominal thickness varies significantly based on the width of the steel plate. For example, below is an excerpt for standard hot-rolled steel plates, based on the 2008 edition which remains representative of the structure in the current standard:
This is the most legally significant part of the document. It defines how much a real-world steel bar can deviate from the drawing. jis g3193 pdf
Option 2: The Technical Comparison (Best for Technical Blogs/Forums) The most frequently consulted part of the standard
Importantly, the standard explicitly states it is not applicable to flat steel bars, covering only flat-rolled products. It defines how much a real-world steel bar
