25、 General requirements1 ScopeThis part of ISO 3098 specifies the general requirements for lettering, in accordance with the other parts of ISO 3098, to be used in technical product documentation (in particular on technical drawings). It includes basic conventions as well as rules for the application
26、of lettering using the following techniques:a) free-hand lettering (by means of an underlaid “grid”);b) templates and manual lettering instruments;c) dry transfer systems;d) numerically controlled lettering and draughting systems.2 Normative referencesThe following documents, in whole or in part, ar

29、 be drawn by means of tubular technical pens conforming with ISO 9175-1.Note 2 to entry: The central line is the basic datum for the design of tools for lettering, e.g. engraving tools for templates, programs for lettering generators.3.2graphic character setfinite set of different graphic characters
