3、BN 0 580 35163 7 National foreword This British Standard is the English language version of EN ISO 5845-1:1999. It is identical with ISO 5845-1:1995. The UK participation in its preparation was entrusted to Technical Committee TDE/4, Engineering drawing, Metrology, precision measurement and other re
4、lated documentation, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European develop
5、ments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publicati
6、ons with their corresponding European publications. The British Standards which implement these international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “
7、Find” facility of the BSI Standards Electronic Catalogue. A British Standard 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 le
8、gal obligations.

25、dization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to
26、 be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft Internationa
27、l Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 5845-1 was prepared by Technical Committee ISO/TC 10, Technical
28、drawings, product definition and related documentation, Subcommittee SC 6, Mechanical engineering documentation. This first edition of ISO 5845-1 is a partial revision of ISO 5261:1981, clause 3 of which has been technically revised. ISO 5845 consists of the following parts, under the general title

31、of fasteners. The representation of fasteners on technical drawings should conform to one of the following two methods, which must meet requirements for microcopying and reproduction: a) conventional drawing of fasteners (according to ISO 128); this method is particularly suitable for drawings conta
32、ining a small number of fasteners, or when the use of symbols may not provide complete understanding; b) symbolic representation; this method is best suited to drawings containing a large number of fasteners (see clauses 4 and 5). Requirements within industries vary considerably; in recognition of t
33、his fact, ISO 5845 is presented in two parts. Part 1 is mainly devoted to structural metal work. Part 2 is mainly devoted to aerospace equipment. Both are recommended for application to other fields as well. 1 Scope This part of ISO 5845 establishes general principles for the simplified representati
34、on of holes, bolts (screws), rivets, etc. on technical drawings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 5845. At the time of publication, the editions indicated were valid. All standards are s
35、ubject to revision, and parties to agreements based on this part of ISO 5845 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 128:1982, Techni

38、part of ISO 5845, the definitions given in ISO 10209-1 and ISO 10209-2 apply. 4 Simplified representation of fasteners 4.1 Representation on projection planes normal to the axes of the fasteners In order to represent holes, bolts and rivets on projection planes normal to their axes, the symbolic rep
39、resentation shall be drawn in continuous thick lines, type A, in accordance with ISO 128. The position of the fastener is indicated by a cross (see Figure 1). Additional information should be indicated in accordance with Table 1 and Table 2 or in accordance with ISO 5845-2. A prominent dot may be pl
40、aced in the centre of the cross in order to facilitate the use of drawing copies as a template (see example in Figure 2). The diameter of the dot shall be five times the thickness of the line used for indicating the cross. 4.2 Representation on projection planes parallel to the axes of the fastener
41、In order to represent holes, bolts and rivets on projection planes parallel to their axes, the symbolic representation shown in Table 2 and Table 3 shall be adopted. The horizontal line of this symbolic representation shall be drawn in a continuous thin line, type B; all other parts shall be drawn i
42、n a thick line, type A, in accordance with ISO 128.

48、ance with the relevant International Standard or other specification in use (see Figure 4). 5.4 The designation of holes, bolts and rivets, when referring to a group of identical elements, can be restricted to one exterior element. In this case the designation shall be preceded by the number of hole
49、s, bolts or rivets constituting the group (see Figure 3 and Figure 4). 5.5 Holes, bolts and rivets equidistant from a centreline may be dimensioned as shown in Figure 3 to Figure 5.
