3Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 764-1:2004,EN764-2:2002 andEN 764-3:2002 and the following apply.
main pressure bearing parts
parts which constitute the envelope under pressure, essential for the integrity of the equipment
pressure vessel
housing and its direct attachments up to the coupling point connecting it to other equipment, designed and built tocontain fluids under pressure
NOTE A vessel may be composed of more than one chamber.
gas, liquid and vapour in their pure phase as well as mixtures thereofNOTE A fluid may contain a suspension of solids.
pipe or system of pipes,tubing, fittings, expansion joints, hoses or other pressure-bearing components, intendedfor the transport of fluid, connected together and integrated into a pressure system
several pieces of pressure equipment assembled by a manufacturer to constitute an integrated and functionalwhole
piping or system of piping designed for the conveyance of any fluid or substance to or from an installation (onshoreor offshore) starting from and including the first isolation device located within the installation and including all theannexed equipment designed specifically for pipelines
maximum allowable pressure (PS)
maximum pressure for which the pressure vessel is designed as specified by the manufacturer
maximum/minimum allowable temperature (TS)
maximum/minimum temperature for which the pressure vessel is designed as specified by the manufacturer
testing group
one of the four groups designed to specify the extent of non-destructive testing and destructive testing necessary in
association with weld joint coefficient, material grouping, welding process, maximum thickness, service temperature
NOTE The testing group of a vessel is not linked to the hazard category.
weld joint coefficient
reduction coefficient related to the testing group and which is applied to the nominal design stress
required thickness
thickness excluding corrosion or any other allowances specified in EN 13445
hazard category
category of the pressure vessel taking into account the potential hazards
testing factor
a factor taking into account the amount of NDT testing in castings, applied on the nominal design stress
material manufacturer
individual or organization that produces material in the basic product form used in the manufacture of pressure equipment
individual or organization that is responsible for design, fabrication, testing, inspection, installation of pressure equipment and assemblies where relevant
NOTE 1 The manufacturer may subcontract one or more of the above mentioned tasks under its responsibility.
NOTE 2 In EU member states the manufacturer is responsible for compliance with the Pressure Equipment Directive 97/23/EC. For those manufacturers outside the EU their authorized representative inside the EU assumes this responsibility.
weld metal, heat affected zone and adjacent base material(s)
4 Interdependency of the parts of the series
Parts 2 to 6 and part 8 of EN 13445, together with Part 1, form a consistent set of specifications which shall be followed for compliance to the standard.
NOTE Parts 7 and 9 of this series are published as a CEN Report and a CEN Technical Report. They are not European Standards.
