It is identical with ISO 2162-1:1993 published by the International Organization for Standardization (ISO). This British Standard partially supersedes BS 308-1. It is envisaged that when the full range of European Standards on technical drawing is implemented BS 308 will be withdrawn. 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 legal obligations.

This 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of an identical text or by endorsement, at the latest by January 1997, and conflicting national standards shall be withdrawn at the latest by January 1997. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. NOTENormative references to International Standards are listed in annex ZA (normative). EN ISO 2162-1:1996 © BSI 10-19983 1 Scope This part of ISO 2162 gives rules for the simplified representation of compression, extension, torsion, disc, spiral and leaf springs on technical drawings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 2162. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 2162 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 2162-2:1993, Technical product documentation Springs Part 2: Presentation of data for cylindrical helical compression springs. ISO 5261:1981, Technical drawings for structural metal work. 3 General In simplified representations, springs are represented as follows. Coiled wire springs: by a line following the axis of the spring wire. Other types of springs: by lines showing the characteristics of the respective type of springs and their elements. The representations shown are examples only. 4 Helical compression springs The following requirements shall be applied for the indication of the geometrical characteristics of wiremade springs on a simplified representation. a) Cross-section of the material Cylindrical: the appropriate graphical symbol in accordance with ISO 5261 () need not be indicated. Other than cylindrical: the appropriate graphical symbol in accordance with ISO 5261 shall be indicated (e.g. , ). b) Direction of helix Right-hand: assumed as normal and the designation RH need not be indicated. Left-hand: exceptional and the designation LH1) shall be indicated. c) Shape of ends Ground: no indication is necessary. Other than ground: the type shall be specified on the drawing, with dimensions if necessary (see ISO 2162-2). 1) In accordance with the rules given for the indication of left-hand screw threads (see ISO 5864:1978, ISO inch screw threads Allowances and tolerances, clause 11).
