3、inde of the Normenausschu Technische Grundlagen (Fundamentals in Technology Standards Committee). The adoption of a number of IS0 Standards (e.g. IS0 724, IS0 965 series) as national standards led the responsible committee to revise the DIN 13 series of standards, The nominal sizes are now based bot
