1 Scope This standard specifies the definition of datums and datum systems for geometrical tolerancing, indications on technical drawings and practical embodiments. This standard is applicable to the basic rules for establishing datums by using simulated datum features and associated features of datum features. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply to this standard, however parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition applies.
