25、ype of finish to ends; and b) design and manufacturing data. 5.2 Representation, data on the spring action and indication of the type of spring ends Graphical representation of the spring shall be in accordance with IS0 2162-1. Data on the spring action shall be indicated prefer- ably by means of a
26、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 shall be indicated in accord- ance with table 2. 5.3 Technical data list The technical data list presented shall includ
27、e 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. Page 4 EN IS0 2162-2 : 1996 No. 1 In particular, for springs working on a rod the mini- mum inside diameter of the coil sh
28、all be stated, and for springs working in a cylinder the maximum out- side diameter of the coil shall be stated. To aid economy in manufacture, tolerances on sizes should not be unnecessarily restrictive. An example of a preprinted data list is given in annex A. This form provides a uniform scheme f
