ISO 2768-1 is an international engineering standard that specifies general tolerances for linear and angular dimensions in manufacturing drawings.
Overview
ISO 2768-1
ISO 2768-1 is an internationally recognized engineering standard developed by the International Organization for Standardization for defining general tolerances in manufacturing and mechanical engineering drawings.
The standard specifies permissible dimensional variations for linear and angular dimensions where individual tolerances are not specifically indicated on technical drawings. ISO 2768-1 helps manufacturers maintain consistency, improve production efficiency, reduce unnecessary detailing on drawings, and ensure standardized quality control practices.
ISO 2768-1 is widely used across industries such as:
- Precision Engineering
- Automotive Manufacturing
- Aerospace
- Machinery & Equipment Manufacturing
- Metal Fabrication
- Tool & Die Manufacturing
- Industrial Components Production
- CNC Machining
- Mechanical Engineering
