The scope of DIN 7161 includes tolerances for linear dimensions (e.g., lengths, widths, heights) and angular dimensions (e.g., angles, tapers) of metallic materials, including: din 7161 pdf
The standard categorizes fits based on how much "wiggle room" or "squeeze" is desired: Clearance Fit: While no longer active for new designs, PDF
He explained that in the 1970s and 80s, West German industry had a problem. They had two parallel universes of general tolerances: the older, highly detailed for linear dimensions (like lengths, steps, chamfers) and DIN 7162 for angles and radii. These were practical, house-made standards. These were practical, house-made standards
: It defines dimensions and tolerances for various types of gauges, including: Plug Gauges : Used for checking holes. [2] Ring Gauges : Used for checking shafts. [2] Snap Gauges : Used for checking external diameters. [2]
