6、Schluche und Armaturen. The modifications made to the previous edition, DIN EN 15182-4:2007-05, were necessary to leave as little room for interpretation as possible. A national standard on high pressure branchpipes did not exist until the publication of the previous edition DIN EN 15182-4:2007-05.

7、This European Standard does not specify requirements relating to couplings for connection to pressure hoses as there are no European Standards on couplings for this purpose. For this reason, these should be specifically agreed at the time of ordering in order to ensure the compatibility of all firef

8、ighting water supply system components in Germany. For high pressure branchpipes PN 40 to DIN EN 15182-4 there are no standardized solid couplings PN 40 available. It is recommended to use screwed connections. Attention is drawn to the possibility that some of the elements of this document may be th

Branchpipes complying with this European Standard may be marked with a suitable markN1)as proof of conformity. Amendments This standard differs from DIN EN 15182-4:2007-05 as follows: a) In t

10、he definitions of the high pressure branchpipes and types, “variable pattern” has been replaced by “adjustable pattern”. b) The reference pressure for the determination of the hydraulic characteristics is now 6 bar 0,1 bar.
