18、994 Foreword This European Standard was taken over by CEN fiom the work of ISOEC 10 Technical drawings, product defmitions and related documentation, of the International Standards Organization (ISO). The Technical Board had decided to submit the nal draft for Formal Vote. The result was positive. T

19、his European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 1995, and conflicting national standards shall be withdrawn at the latest by April 1995. According to the CEN/CENELEC Internal Regulations, the

20、 following countries are bound to implement this European Standard Austria, Belgium, Denmark, Finiand, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom. Introduction IS0 9222 provides rules for the simplined repre

21、sentation of seals. The principle of drawing practice is to depict the object to scale using lines. In simplified representations, only essential features are shown, preferably in outline (in order to save time and effort). The degree of simplification depends on *e kind of object represented, the s

22、cale of the drawing and the purpose of the documentation. This means that either a general simplified representation or a detailed one may be used. A detailed representation shows more details of a seal, for example the configuration of lips. In order to avoid misunderstanduigs, only one kind of sim

23、plification, either the general or the detaild simplified representation, should be used on a drawing.
