an alternative to the functional tolerances in Annex B, BS EN  does allow the use of BS EN ISO ; this is more likely to be used in cases of. International Standard ISO was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC Specifies general tolerances for linear and angular dimensions and for shape and position of welded structures in four classes, these being based on customary.
