Description:This European Standard specifies general tolerances for linear and angular di-mensions and for shape and position of welded structures in four tolerance clas-ses, these being based on customary workshop accuracy. The main criterion for the selection of a particular tolerance class should be the functional require-ments which are to be met. The applicable tolerances are always those which are stated in the drawing. Instead of specifying individual tolerances the tolerance classes according to this standard may be used. General tolerances for linear and angular dimensions and for shape and position as specified in this standard apply for weldments, welding assemblies and welded structures etc. Special provisions may be necessary for complex structures. The specifications given in this standard are based on the principle of indepen-dency as specified in ISO 8015, according to which the dimensional and geometri-cal tolerances apply independently of each other. Manufacturing documentation in which linear and angular dimensions or indica-tions for shape and position are presented without individually indicated tole-rances shall be deemed incomplete if there is no, or inadequate, reference to general tolerances. This does not apply to temporary dimensions.
