DIN 7603 en密封垫标准

ICS 23.040.80 Dichtringe 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 Rohrverschraubungen of the Normenausschuss Rohrleitungen und Dampfkesselanlagen (Pipelines and Pressure Vessels Standards Committee). Amendments This standard differs from the November 1994 edition as follows: a) The dimensions and mass of ring seals and gaskets which are not to be used for new designs are now dealt with in Appendix A. b) Dimension r1 has been specified for type C gaskets. c) Dimension d1 has been corrected for gaskets of nominal size 21 · 26. d) The specifications for service temperatures have been amended (cf. table 3). e) The standard has been editorially revised.
