This European Standard is applicable to metallic piping above ground, ducted or buried, irrespective of pressure. This European Standard is not applicable to: ? Pipelines and their accessories; ? Stream waterways such as penstocks, pressure tunnels, pressure shaft for hydro-electric-installations and their related specific accessories; ? Piping for vehicles covered by the EEC type approval procedures as laid down in Directives 70/156/EEC 1, 74/150/EEC 2 and 92/61/EEC 3; ? Items specifically designed for nuclear use, failure of which may cause an emission of radioactivity; ? Well-control equipment used in the petroleum, gas or geothermal exploration and extraction industry and in underground storage which is intended to contain and/or control well pressure, including the piping; ? Piping of blast furnaces including the furnace cooling, hot blast recuperators, dust extractors and blast furnace exhaust gas scrubbers and direct reducing cupolas including the furnace cooling, gas converters and vacuum furnaces and pans for melting, re-melting de-gassing and casting of steel and non ferrous metals; ? Enclosures for high voltage electrical equipment such as switchgear, control gear and transformers; ? Pressurized pipes for the containment of transmission systems such as for electrical power and telephone cables; ? Permanently fixed piping for ships, rockets, aircraft and mobile offshore units; ? Internal piping in medical devices as defined in the Directive 93/142/EEC 4 concerning medical devices; ? Internal piping of boilers and piping integral to pressure vessels. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications.

Specific definitions are given in the relevant Parts of this European Standard. 3.1.1 ambient temperature temperature of the surrounding atmosphere in the immediate vicinity of the piping system 3.1.2 piping system piping pipe or system of pipes for the conveyance of fluids within an industrial site NOTE 1A piping system can be regarded as one single system provided it conveys substances having the same properties and it is as a whole designed for the same allowable pressure. NOTE 2Interruption by different components such as pumps, machines, vessels etc. does not preclude the integration to one single piping. 3.1.3 fluid gases, liquids and vapours in pure phase as well as mixtures thereof NOTE: A fluid may contain a suspension of solids. 3.1.4 manufacturer person or organization that takes full responsibility for the design and manufacture of the piping system and its conformity to EN 13480 NOTE 1 The manufacturer is responsible for carrying out all relevant production processes and testing as specified in the applicable standards. NOTE 2If a manufacturer employs subcontractors or fabricators/installers for certain items he is responsible for their work. NOTE 3In the EC Member States a manufacturer or his representative is responsible for the conformance of a piping system he puts on the market, with the essential safety requirements of the PED.
