This DVGW Standard G 463 shall apply in conjunction with DIN EN 1594 ”Gas infrastructure – Pipelines for maximum operating pressure over 16 bar – Functional requirements“. DIN EN 1594 defines the general fundamentals for designing, constructing, operating and maintaining high pressure gas pipelines. These general fundamentals constitute the minimum requirements agreed upon by the European experts in- volved in the standardisation process and shall, therefore, be complemented by detailed technical rules and / or national standards to be implemented thereafter. This DVGW Standard G 463 specifies the detail- ing and implementation of the design and construction processes on the basis of the tried and trusted long-standing safety philosophy of the German gas sector. DVGW Standard G 466-1 shall apply to the operation and maintenance of suchpipelines.
