Dimensions
Continued on pages 2 to 8.
Foreword
This standard has been prepared by Technical Committee  Rohrverschraubungen  of the Normenausschuss Rohrleitungen und Dampfkesselanlagen  (Pipelines and Pressure Vessels Standar
ds Committee), taking into account the specifications of DIN EN ISO 9974-1 and DIN EN ISO 9974-3.
Amendments
This standard differs from the February 1992 edition as follows:
a)Dimensions d 4 for ports and d 3 for stud ends have been adopted from DIN EN ISO 9974-1 and DIN EN ISO 9974-3, respectively.
b)Type E stud ends are no longer specified.
c)Tolerances on d 3 and r  have been specified (cf. table 1).d)The standard has been editorially revised.Previous editions
DIN KrG 403: 1931-12; DIN 7602: 1935-10, 1947-05; DIN 3852-1: 1953x-08, 1964-10, 1966-05, 1978-09,1992-02.
All dimensions are in millimetres.
1Scope
This standard specifies the dimensions and designation for ports and stud ends with metric fine pitch thread for use with compression couplings, valves and screw plugs.
NOTE:Ports and stud ends conforming to this standard should not be used for new designs in fluid power applications.
This standard, together with DIN EN ISO 9974-1and DIN EN ISO 9974-3,September 2000 editions,supersedes
February 1992 edition.
