ISO 286-1:2010建立了用于以下类型特征线性尺寸公差的ISO代码系统:a）圆柱体；b） 两个平行相对的表面。 ISO 286-1:2010定义了该代码系统的基本概念和相关术语。它从众多可能性中为一般用途提供了公差等级的标准化选择。 此外，它定义了两个尺寸特征之间的配合的基本术语，不受方向和位置的限制，并解释了“基本孔”和“基本轴”的原理。

ISO 286-1:2010 establishes the ISO code system for tolerances to be used for linear sizes of features of the following types: a) cylinder; b) two parallel opposite surfaces. ISO 286-1:2010 defines the basic concepts and the related terminology for this code system. It provides a standardized selection of tolerance classes for general purposes from amongst the numerous possibilities. Additionally, it defines the basic terminology for fits between two features of size without constraints of orientation and location and explains the principles of “basic hole” and “basic shaft”.
