The principle of drawing practice is to depict the object to scale using lines. In simplified representations, only essential fea
23、tures are shown, preferably in outline (in order to save time and effort). The degree of simplification depends on the kind of object represented, the scale of the drawing and the purpose of the documentation. This means that either a general simplified representation or a detailed one may be used.
24、A detailed representation shows more details of a seal, for example the configuration of lips. In order to avoid misunderstandings, only one kind of simplification, either the general or the detailed simplified representation, should be used on a drawing. 1 Scope This part of ISO9222 specifies a det
25、ailed simplified representation for various seals. This representation should be used in cases where it is not necessary to show the exact shape and details of the seals, for example in assembly drawings. 2 Normative references The following standards contain provisions which, through reference in t

All standards are subject to revision, and parties to agreements based on this part of ISO9222 are encouraged to investigate the possibility of applying the most recent editions of
