While Part 1 deals with the size of features, Part 2 addresses the form and position of features (Geometrical Dimensioning and Tolerancing, or GD&T). This section covers tolerances for:

Angular tolerances scale based on the length of the shorter leg of the angle being measured: Shorter Leg Length Range (mm) Over 10 to 50 Over 50 to 120 Over 120 to 400 ±1∘plus or minus 1 raised to the composed with power m (Medium) ±1∘plus or minus 1 raised to the composed with power c (Coarse) ±1∘plus or minus 1 raised to the composed with power v (Very Coarse) ±3∘plus or minus 3 raised to the composed with power ±2∘plus or minus 2 raised to the composed with power ±1∘plus or minus 1 raised to the composed with power ISO 2768 Part 2: Geometrical Tolerances

ISO 2768-1 defines four tolerance classes (from loose to tight): iso 2768 general tolerances pdf exclusive

ISO 2768 is a standard published by the International Organization for Standardization (ISO) that defines general tolerances for various types of features, including:

If you are setting up a drafting standard for your team, let me know:

When a drawing includes a note such as ISO 2768-mK , it instructs the machinist to use specific tolerance ranges defined by the standard. This eliminates the need to write next to dozens of non-critical features. Key Benefits of General Tolerances Indicates linear dimensions and High (H) geometric precision

When reviewing an engineering title block, the linear and geometric designations are paired together. For example, means:

The standard provides a set of tolerance classes, each with its own set of tolerance values, which can be used to specify the acceptable limits of variation for a particular feature.

Straightness, flatness, perpendicularity, symmetry, circular run-out. This section covers tolerances for: Angular tolerances scale

Standard PDFs from ISO cost around 150 CHF ($160 USD). Most engineers rely on second-hand tables or company internal documents. When searching for an , you want a version that is:

Regulated using the same numerical table as straightness and flatness, using the longer of the two legs as the nominal length reference.
