Din 7161 Pdf Link [SAFE]
DIN 7161, which provided ISO tolerance deviations for dimensions from 1 to 500 mm, is a historical German technical standard that has largely been succeeded by modern ISO 286 standards. It remains relevant for interpreting legacy blueprints and understanding fundamental mechanical fit principles in engineering. For official documentation and modern equivalent data, refer to ISO 286 standards or official standards bodies.
The tolerances are specified in terms of limits of deviation (e.g., +/− 0.1 mm) or tolerance ranges (e.g., 0.1 mm to 0.5 mm). din 7161 pdf
Measurement Range: Covers nominal dimensions from 1 mm up to 500 mm. DIN 7161, which provided ISO tolerance deviations for
Primary Focus: ISO allowances for internal dimensions (holes). Lengths and widths: up to 630 mm (exception:
- Lengths and widths: up to 630 mm (exception: up to 2000 mm for some tolerance classes)
- Heights and thicknesses: up to 400 mm
Q: How do I determine the tolerance class for my part? A: The tolerance class is typically determined based on the part's functional requirements, material, and manufacturing process. Consult the DIN 7161 standard or a relevant industry guideline for guidance.
