EN ISO 286-1-2010 几何产品规范(GPS).线性尺寸公差的ISO编码系统.第1部分:公差,偏差和配合的基础［代替:CEN EN 20286-1］
Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 1: Basis of tolerances, deviations and fits (ISO 286-1:2010)
This part of ISO 286 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.It defines the basic concepts and the related terminology forThis code system. It provides a standardizedselection 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 oforientation and location and explains the principles of “basic hole” and “basic shaft”.
