Major Revision of JIS Standards! The Concept of "Size" That 3D CAD Designers Should Know

Are 'dimensional tolerances' outdated? Adapt to international standards in design.

In 2016, JIS B 0420:2016 was established, changing the traditional term "dimension" in part to **"size"** and "dimensional tolerance" to **"size tolerance."** The background of this standard change is the growing adoption of the concept of GPS (Geometric Product Specification) in Western countries, raising concerns that Japan would fall behind international standards. The new standard strongly encourages a shift in design philosophy from a focus on traditional dimensional tolerances to geometric tolerances. 3D CAD designers must urgently understand the requirements of this new standard and reflect them in their designs. The revision of JIS B 0401:2016 was also carried out simultaneously, changing the old name "Dimensional Tolerances and Fits" to "ISO Code Method for Size Tolerances Related to Length." Please refer to the materials for specific methods of compliance with the new JIS standards and accurate definitions of terms. *For more details, please download the PDF or feel free to contact us.*
