- Scope
- This part of GB/T 1800 establishes the ISO code system for linear dimensional tolerances, which applies to the following types of dimensional elements: a) cylindrical surface; b) two opposite parallel surfaces. This section defines the basic concepts and related terms of the ISO code system for linear dimensional tolerances, and provides a standardized method for selecting common tolerance zone codes from a variety of options. In addition, this section defines the basic terms of the two-dimensional elements that are not constrained by direction and position, and explains the principles of "reference hole" and "reference axis".
