If both conditions are met, the part is within the DIN 7161 specified tolerance. Where to find the document
This comprehensive article explores the significance of DIN 7161, its technical applications, how it integrates into the broader ISO system of limits and fits, and what you need to know when looking for the official documentation. What is DIN 7161?
If you are working on a specific design or trying to interpret an old blueprint, let me know or tolerance code (like H7, m6, etc.) you are trying to find. I can help you look up or calculate the exact upper and lower deviations you need for your project. Share public link din 7161 pdf
Understanding DIN 7161: ISO Allowances for Internal Dimensions (Holes)
For example, a specification of on a engineering drawing points directly to these tables to define a nominal 20 mm hole with an IT7 tolerance grade. Types of Fits Covered Under the DIN Framework If both conditions are met, the part is
Note: Many engineering universities and machinery handbooks offer free, abridged tolerance chart PDFs that cover the most common H7/g6, H7/h6, and H7/p6 values for quick shop-floor reference. How to Read a DIN 7161 Tolerance Table
These often provide the specific tolerance values in microns, categorized by nominal sizes. Related Standards If you are working on a specific design
DIN 7161 is a German standard (DIN) that specifies the requirements for the geometrical and dimensional tolerancing of technical parts. The standard is titled "Form- und Lagetoleranzen" which translates to "Form and positional tolerances".

DIN 7161 was never an isolated document. It was part of a larger, interconnected "DIN family" of standards from the 1960s. Understanding these related standards helps to provide context:
