This standard is intended to simplify drawings. It specifies general tolerances for shape and position for welded structures in four tolerance classes, these being based on customary workshop accuracy. The main criterion for the selection of a particular tolerance class should be the functional requirements which are to be met. If tighter geometrical tolerances are required, or if larger tolerances are both permitted and more economical, then they shall be indicated individually in accordance with ISO 1101. General tolerances of shape and position as specified in this standard apply for weldments, welding assemblies and welded structures when reference is made to this standard on drawings or related technical documents, e.g. delivery specifications, in accordance with clause 5. The specifications given in this standard are based on the principe of independency as specified in ISO 8015, according to which dimensional and geometric tolerances apply independently of each other. Where other tolerancing principles are to be followed, this shall be explicitly stated in the drawings.
