This volume, DIN Handbook 15/2, contains standards on dimensions and technical delivery conditions for steel pipes and tubes which had been previously contained in DIN Handbook 15. Eleven European Standards and one national standard (DIN 2460 "Steel water pipes and fittings") are revisions. New parts of the DIN EN 10216 and DIN EN 10217 series (on welded and seamless steel tubes for pressure purposes) which have been published since the last edition of DIN Handbook 15 have also been included.
