This standard is included in DIN Handbook 123, 303 and 304. Specifies the symbols and additional indications of surface texture to be indicated on technical drawings. The basic symbol for surface texture consists of two legs of unequal length inclined at approximately 60 Degrees to the line representing the considered surface. A bar added to the basic symbol means that the removal of material by machining is required. A circle added to the basic symbol means that removal of the material is not permitted.
