6、al foreword This Part of BS EN ISO9222 has been prepared by Technical Committee TDE/4 and is the English language version of EN ISO9222-1:1995 Technical drawings Seals for dynamic application Part 1: General simplified representation, published by the European Committee for Standardization (CEN). It
7、 is identical with ISO9222-1:1989, published by the International Organization for Standardization (ISO). This Part of BS EN ISO9222 partially supersedes BS308-1. It is envisaged that when the full range of European Standards on technical drawing is implemented BS308 will be withdrawn. A British Sta
8、ndard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-reference Publication referred to Corresponding

The principle of drawing prac
20、tice 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 the kind of object represented, the scale of the drawing and the purpose of the docum
21、entation. 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 (see ISO9222-2). In order to avoid misunderstandings, only one kind of simplification, either the general
22、or the detailed simplified representation, should be used on a drawing. 1 Scope This part of ISO9222 specifies the general simplified representation for seals. This representation should be used when it is not necessary to show the exact shape and details of the seals, for example in assembly drawin
23、gs. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of ISO9222. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this part
24、of ISO9222 are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 128:1982, Technical drawings General principles of presentation. 3 Method of represe
25、ntation 3.1 Lines All features of the simplified representation shall be drawn with the same line thickness used for all other visible outlines and edges on the drawing (line type A, ISO128). 3.2 Scale The contour of the simplified representation shall be drawn to the same scale as used for the draw
26、ing. 3.3 General simplified representation For general purposes (without specified lip configuration where it is not necessary to show the exact contour), the seal shall be represented by a square and a freestanding diagonal cross centred in the square (see Figure 1). The cross shall not touch the o
27、utlines. This representation shall be used in the space on one or both sides of the axis (see for example Figure 4, for the case of a horizontal axis). The representation shown in Figure 1 shall be used only when the sealing direction is unimportant. If it is necessary to show the sealing direction,
28、 an arrowhead may be added to the diagonal cross (see for example Figure 2). If it is necessary to show the exact contour of a sealing composition, it should be represented by the true outline of its cross-section, with the diagonal cross in a central position (see Figure 3). The cross shall not tou
29、ch the outlines. Figure 1 Figure 2 ENISO 9222-1:1995 4 BSI 02-1999 This representation shall be used in the space on one or both sides of the axis (see for example Figure 4, for the case of a horizontal axis). In cases where the seal permits more than one direction of assembly, the desired direction
30、 of assembly shall be given, for example by text or specification. 4 Hatching In simplified representations, hatching should be avoided. If, in special cases, greater clarity is necessary (for example in more detailed representations or illustrations for catalogues in accordance with ISO9222-2), all
31、 inserts and similar elements of the seals should be hatched in the same direction and with continuous thin lines (type B, ISO 128; see Figure 5) or blackened (see Figure 6).
