Gas infrastructure. Pressure testing, commissioning and decommissioning procedures. Functional requirements Ingestion-build-51215 PE pipes with co-extruded layers1 Scope This European Standard describes common principles for pressure testing, commissioning and decommissioning of gas infrastructures as covered by the functional European Standards of the Technical Committee CEN TC 234, see Annex B. They have been extracted from the detailed codes of practice and operating manuals in the member countries. This European Standard does not cover installation pipework which is covered by EN 1775.
