2、ndurchmesser von 40 mm bis 300 mm December 1986 edition. In keeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker. Foreword This standard has been prepared by Technical Committee Gewind
3、e 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 both o
4、n the basic dimensions specified in DIN IS0 724 and on the nominal profiles specified in DIN 13-19. The nominal sizes of the external thread minor diameters specified here have been calculated taking the root radius as being equal to H/6. The thread designation is to be found in DIN IS0 965-1. See t
5、he table in the Explanatory notes of DIN 13-1 for an overview of DIN and DIN IS0 Standards for screw threads. Amendments This standard differs from the December 1986 edition in that the nominal sizes are now to be calculated on the basis of DIN 13-1 9. Previo us edit ions DIN 13-40: 1961-05, 1964-06
