<p class="MsoBodyText" style="mso-layout-grid-align: none; text-autospace: none;"><span lang="EN-GB" style="mso-bidi-font-size: 12.0pt;">This document specifies general tolerances for linear and angular dimensions and for shape and position of welded structures in four tolerance classes, based on customary workshop accuracy. The main criterion for selection of a particular tolerance class is based on the functional requirements which are to be met.</span></p> <p class="MsoBodyText" style="mso-layout-grid-align: none; text-autospace: none;"><span lang="EN-GB" style="mso-bidi-font-size: 12.0pt;">The applicable tolerances are always those which are stated in the drawing.

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!
