19、. 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of an identical text or by endorsement, at the latest by January1997, and conflicting national standards shall be withdrawn at the latest by January1997. According to the CEN/CENELEC Internal Regulations
20、, 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.

22、ical product documentation intended for e.g. tender and/or order 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 standa
23、rds 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.

26、spring shall be in accordance with ISO 2162-1. Data on the spring action shall be indicated preferably by means of a load deflection chart (or graph) showing the predominant requirements necessary for the functioning of the spring together with any additional requirements. The type of spring ends sh
27、all be indicated in accordance with Table 2. 5.3 Technical data list The technical data list presented shall include all information necessary for the manufacture of the springs. Possibilities for the adaptation of a certain spring to given requirements during manufacture shall be specified. In part
28、icular, for springs working on a rod the minimum inside diameter of the coil shall be stated, and for springs working in a cylinder the maximum outside diameter of the coil shall be stated. To aid economy in manufacture, tolerances on sizes should not be unnecessarily restrictive. An example of a pr
