Amendments This standard differs from DIN 2353:1998-12 as follows: a) the normative references and Bibliography have been u
8、pdated; b) in 3.2 the requirements relating to stud fittings with type C (taper) stud end have been revised and the pressures for the heavy duty “S” series in Table 2, Table 3 and Table A.1 have been reduced; c) the former Clause 4 “Connecting dimensions and length of free pipe end” is now the infor
9、mative Annex A; d) the former Clause 5 “Parts list” has been deleted; e) the new Clause 5 (formerly Clause 7) “Design features” has been revised; f) the standard has been editorially revised. The following corrections have been made to the DIN 2353:2012-09 edition: a) in Table 1, column “Approx. dis
10、tance from centre to pipe e3”, the value “1” has been replaced by “15” in row L6; b) in Table 3, thread size d1 of stud end as in DIN 3852-1 and DIN 3852-2 for types “BB, J, P” the dimension “G A” has been changed to “G A” in rows L22 and S20.

This
12、standard gives an overview of the types and dimensions of compression fittings and couplings that are assembled from standardized parts and are not covered in DIN EN ISO 8434-1. It can be used to select fittings and determine the size of assemblies. NOTE Standard design straight stud ends are covere
