EN ISO 13920: 1996 Welding - General tolerances for welded constructions - Dimensions for lengths and angles - Shape and position (ISO 13920: 1996)

This European Standard specifies general tolerances for linear and angular dimensions and for shape and position of 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.
