In technical drawing, specifying every single geometric tolerance is time-consuming and cluttering. ISO 2768-2 simplifies this by providing "general tolerances." If a drawing does not have a specific geometric tolerance (like flatness or symmetry) noted for a feature, the standard values from ISO 2768-2 apply automatically based on the chosen accuracy class. The Three Tolerance Classes iso 2768 -2

These tolerances prevent surfaces from being too bowed or wavy. Measured based on the length of the surface. You can copy, paste, and adapt this for

The standard is divided into three accuracy classes. Designers select one based on the functional requirements of the part and the capability of the machinery: Fine (tightest tolerances) Class K: Medium (standard machine shop work) Class L: Coarse (for less critical components) Key Geometrical Features Covered Designers select one based on the functional requirements

The purpose of this report is to document and verify the geometrical tolerances applied to machined/drawn features where no individual tolerance is specified on the drawing, in accordance with .

A central concept within ISO 2768-2 is the categorization of tolerances into classes. The standard recognizes that different industries and different parts require different levels of precision. Consequently, it defines three classes of general geometrical tolerances: .
