标准摘要
[中文适用范围]： ISO 286 的这一部分给出了根据 ISO 286-1 中给出的表格计算出的孔和轴常用公差等级的极限偏差值。 ISO 286 的这一部分涵盖了上限偏差 ES（针对孔）和 es（针对轴）以及下限偏差 EI（针对孔）和 ei（针对轴）的值（见图 1 和 2）。 [外文原描述]： ISO 286-2:2010 gives values of the limit deviations for commonly used tolerance classes for holes and shafts calculated from the tables given in ISO 286‑1. ISO 286-2 covers values for the upper limit deviations e U, hole (for holes) and e U, shaft (for shafts) and the lower limit deviations e L, hole (for holes) and e L, shaft (for shafts). The ISO system for tolerances on linear size provides a system of tolerances and deviations suitable for features of the following types: cylinders; two parallel opposite 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 ISO 286-2 equally apply to workpieces of other than circular sections.
