Endorsement notice The text of ISO 286-2:2010 has been approved by CEN as a EN ISO 286-2:2010 without any modification. “EN ISO 286-2:2010 (E) DIN EN ISO 286-2:2010-11 3 Introduction This part of ISO 286 is a geometrica
27、l product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain links 1 and 2 of the chain of standards on size in the general GPS matrix. For more detailed information on the relationship of this part of ISO 286 to the GPS matrix model,
28、 see Annex B. The need for limits and fits for machined workpieces was brought about mainly by the requirement for interchangeability between mass-produced parts and the inherent inaccuracy of manufacturing methods, coupled with the fact that “exactness” of size was found to be unnecessary for most
29、workpiece features. In order that the fit function could be satisfied, it was found sufficient to manufacture a given workpiece so that its size lay within two permissible limits, i.e. a tolerance, this being the variation in size acceptable in manufacture while ensuring the functional fit requireme
30、nts of the product. Similarly, where a specific fit condition is required between mating features of two different workpieces, it is necessary to ascribe an allowance, either positive or negative, to the nominal size to achieve the required clearance or interference. ISO 286 gives the internationall
31、y accepted code system for tolerances on linear sizes. It provides a system of tolerances and deviations suitable for two types of feature: “cylinder” and “two parallel opposite surfaces”. The main intention of this code system is the fulfilment of the function fit. The terms “hole”, “shaft” and “di
32、ameter” are used to designate the types of feature of cylinders (e.g. for the tolerancing of the diameter of a hole or shaft). For simplicity, they are also used for two parallel opposite surfaces (e.g. for the tolerancing of the thickness of a key or the width of a slot). The pre-condition for the
33、application of the ISO code system for tolerances on linear sizes for the features forming a fit is that the nominal sizes of the hole and the shaft are identical. The previous edition of ISO 286-2 (published in 1988) had the envelope criterion as the default association criterion for the size of a
34、feature; however, ISO 14405-1 changes this default association criterion to the two-point size criterion. This means that form is no longer controlled by the default specification of size. In many cases, the diameter tolerances specified in this part of ISO 286 are not sufficient for effective contr
35、ol of the intended function of the fit. The envelope criterion specified in ISO 14405-1 may be required. In addition, the use of geometrical form tolerances and surface texture requirements may improve the control of the intended function. A general graphical representation of the relationship betwe
36、en the respective tolerance classes and their deviations is given in Annex A. EN ISO 286-2:2010 (E) DIN EN ISO 286-2:2010-11 4 1 Scope This part of ISO 286 gives values of the limit deviations for commonly used tolerance classes for holes and shafts calculated from the tables given in ISO 286-1. Thi
37、s part of ISO 286 covers values for the upper limit deviations ES (for holes) and es (for shafts), and the lower limit deviations EI (for holes) and ei (for shafts) (see Figures 1 and 2). NOTE In the tables of limit deviations, the values of the upper limit deviation ES or es are shown above the val
38、ues of the lower limit deviation EI or ei except for tolerance classes JS and js which are symmetrical about the zero line. The ISO system for tolerances on linear size provides a system of tolerances and deviations suitable for features of the following types: a) cylinders; b) two parallel opposite
39、 surfaces. For simplicity, and also because of the importance of cylindrical workpieces of circular section, only these are referred to explicitly. It should be clearly understood, however, that the tolerances and deviations given in this part of ISO 286 equally apply to workpieces of other than cir
40、cular sections. In particular, the term “hole” or “shaft” is used to designate features of the cylinder type (e.g. for the tolerancing of the diameter of a hole or shaft) and, for simplicity, these terms are also used for two parallel opposite surfaces (e.g. for the tolerancing of the thickness of a
41、 key or the width of a slot). For further information on terminology, symbols, the basis of the system, etc., see ISO 286-1.
