- Scope
- This standard specifies the terms and definitions, basic provisions, drawing representation methods and application examples of maximum entity requirements, minimum entity requirements and reversible requirements. These requirements apply only to dimensional elements. This standard applies to situations where workpiece dimensions and geometric tolerances are related to each other to meet their specific functions, such as meeting part assemblability (maximum entity requirements) and ensuring minimum wall thickness (minimum entity requirements), but maximum entity requirements and minimum entity requirements also apply to other functional requirements. Taking into account the correlation between size and geometric elements, when maximum entity requirements, minimum entity requirements or reversible requirements are adopted, the independence principle defined in GB/T4249 is no longer applicable.
