適用范圍：This part of ISO 286 gives values of the limit deviations for commonly used tolerance classes for holes andshafts calculated from the tables given in ISO 286-1. This part of ISO 286 covers values for the upper limitdeviations ES (for holes) and es (for shafts), and the lower limit deviations EI (for holes) and ei (for shafts)(see Figures 1 and 2).The ISO system for tolerances on linear size provides a system of tolerances and deviations suitable forfeatures of the following types:a) cylinders;b) two parallel opposite surfaces.For simplicity, and also because of the importance of cylindrical workpieces of circular section, only these arereferred to explicitly. It should be clearly understood, however, that the tolerances and deviations given in thispart of ISO 286 equally apply to workpieces of other than circular sections.In particular, the term “hole” or “shaft” is used to designate features of the cylinder type (e.g. for thetolerancing of the diameter of a hole or shaft) and, for simplicity, these terms are also used for two parallelopposite surfaces (e.g. for the tolerancing of the thickness of a key or the width of a slot).For further information on terminology, symbols, the basis of the system, etc., see ISO 286-1.
