What is ISO 2768?

In my understanding, standard tolerance means that all mechanical product production will have an acceptable floating range, and it is also an internationally recognized standard. I searched for a more specific expression,At its core, tolerances specify the limits of allowable variation in physical dimensions. It defines the acceptable range of dimensions such as length, width, or diameter of an object. Standard tolerances utilize generally accepted tolerance ranges rather than arbitrary or individually determined tolerance ranges.

Importance of standard tolerances: 😄 (I think that)
1. Having standard tolerances can promote international trade, avoid unnecessary disputes over manufactured products due to regional differences, and reduce manufacturing costs.
2. Ensure quality. In industries such as automobiles or electronics, parts are often produced by different suppliers. Standard tolerances ensure that these parts can be assembled and used well even if they are produced in different environments and countries.
