标准摘要
[中文适用范围]： ISO 286 的这一部分建立了 ISO 公差编码系统，用于以下类型的特征的线性尺寸：a) 圆柱；b) 两个平行相对表面。它定义了此编码系统的基本概念和相关术语。它从众多可能性中提供了用于一般用途的标准化公差等级选择。此外，它还定义了两个尺寸特征之间不受方向和位置限制的配合的基本术语，并解释了“基孔”和“基轴”的原理。 [外文原描述]： 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”.
