Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 2 : tables of standard tolerance classes and limit deviations for holes and shafts

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 eU, hole (for holes) and eU, shaft (for shafts) and the lower limit deviations eL, hole (for holes) and eL, 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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
