In engineering, tolerances play a crucial role in ensuring the interchangeability of parts and the overall quality of products. Tolerances define the acceptable limits of variation in the dimensions of a part, allowing for a certain degree of error in the manufacturing process. One widely used standard for general tolerances is ISO 2768, which consists of two parts: ISO 2768-1 for linear dimensions and ISO 2768-2 for features without individual tolerance indications. iso 2768 -2

In the realm of mechanical engineering and manufacturing, the translation of a designer’s intent into a physical product is a process fraught with variability. No machine can produce a perfectly flat surface, a perfectly round hole, or a perfectly straight edge. Historically, managing these imperfections required exhaustive notation on technical drawings, cluttering the page and obscuring critical design features. To address this, the International Organization for Standardization (ISO) introduced the ISO 2768 standard. While Part 1 of this standard addresses linear and angular dimensions, deals specifically with geometric tolerances. This essay explores the function, classification, and critical importance of ISO 2768-2 in simplifying technical communication and ensuring functional manufacturability.

To legally apply these standards, a designer must include a note in or near the title block of the technical drawing. ISO 2768 - [Part 1 Class][Part 2 Class] Example: ISO 2768-mK m : Medium linear tolerance (from Part 1). K : Medium geometric tolerance (from Part 2).

You can copy, paste, and adapt this for internal documentation, quality reports, or engineering summaries.

Circular run-out ensures that a rotating feature is concentric and "true" to its axis. Class H: 0.1mm Class K: 0.2mm Class L: 0.5mm How to Indicate ISO 2768-2 on a Drawing and adapt this for internal documentation

Prevents over-engineering by allowing wider tolerances where precision isn't critical.

ISO 2768-2 is widely applied in various industries, including:
