97/23/EC - Pressure equipment

Directive 97/23/EC aims to harmonize the laws of EU Member States regarding pressure equipment with a maximum allowable pressure exceeding 0.5 bar. It applies to the design, manufacture, and conformity assessment of pressure equipment and assemblies, including vessels, piping, safety, and pressure accessories. The Directive excludes certain equipment categories such as pipelines, simple pressure vessels, aerosol dispensers, vehicle-related equipment, and specific apparatus covered by other Directives or international Conventions. It lays down essential safety requirements to ensure the safe operation of pressure equipment and facilitates free movement of compliant products within the internal market. Harmonized standards and European material approvals support compliance, while conformity assessment procedures vary by equipment category based on associated risks. The Directive mandates CE marking to signify compliance, provides for authorization of user inspectorates, and permits temporary marketing of equipment under national rules during the transition phase. The overall objective is to remove technical barriers to trade while ensuring a high level of safety for users, animals, and property from pressure hazards.

Purpose

Directive 97/23/EC aims to harmonize the laws of EU Member States relating to the design, manufacture, and conformity assessment of pressure equipment and assemblies. Its goal is to ensure the free movement of pressure equipment within the internal market while maintaining a high level of safety for persons, domestic animals, and property. It addresses disparities in national regulations and certification procedures that could constitute barriers to trade. The directive applies to pressure equipment with a maximum allowable pressure (PS) greater than 0.5 bar.

Key obligations

  • Scope and Definitions: The directive defines crucial concepts including 'pressure equipment', 'vessels', 'piping', 'safety accessories', and 'pressure accessories'. Pressure is gauge pressure relative to atmospheric pressure.
  • Essential Safety Requirements: Pressure equipment must meet general and specific essential requirements tailored to different types of equipment to ensure safety.
  • Conformity Assessment: Member States must implement procedures for assessing compliance based on the level of hazard posed by the equipment. These include final inspections and proof tests for higher-risk categories (III and IV).
  • CE Marking: Pressure equipment conforming to the directive must bear the CE marking, indicating compliance with safety requirements and other applicable EU directives.
  • Use of Harmonized Standards: Compliance is eased through European harmonized standards established by recognized bodies (CEN and CENELEC), which provide presumption of conformity to essential requirements.
  • Materials: The directive demands the use of safe materials, preferably those with European approvals, to satisfy essential safety requirements.
  • User Inspectorates: Member States may authorize user inspectorates to carry out conformity assessment tasks under defined criteria.

Direktiva 97/23/ES ureja usklajevanje zakonodaje držav članic EU glede načrtovanja, izdelave in ocene skladnosti tlačne opreme ter sklopov, katerih največji dovoljeni tlak presega 0,5 bara. Namen direktive je odstraniti tehnične ovire za prosti pretok tega blaga znotraj notranjega trga, hkrati pa zagotoviti visoko raven varnosti za ljudi, domače živali in premoženje. V direktivi so opredeljene bistvene varnostne zahteve, ki vključujejo tako splošne kot posebne zahteve glede različnih vrst tlačne opreme, kot so posode, cevovodi, varnostne in tlačne armature ter sklopi tlačne opreme. Prav tako določa postopke ocene skladnosti glede na stopnjo tveganja in razred opreme, vključno z označevanjem CE, ki pomeni skladnost z direktivo. Direktiva izključuje določene vrste opreme, na primer neposredno povezane z vozili, medicinskimi pripomočki ali jedrsko rabo. Države članice morajo zagotoviti nadzor trga in po potrebi začasne ukrepe za omejitev uporabo tlačne opreme, ki predstavlja posebno tveganje. Prav tako predvideva možnost predstavitve opreme na sejmih ob upoštevanju varnostnih ukrepov. Standardizacija na evropski ravni pomaga pri dokazovanju skladnosti z bistvenimi zahtevami.

Namen

Direktiva 97/23/ES je namenjena približevanju zakonodaje držav članic Evropske unije na področju tlačne opreme, da bi zagotovila prosti pretok takšne opreme na notranjem trgu EU in hkrati zagotovila visoko stopnjo varnosti za ljudi, domače živali in premoženje. Poudarek je na uskladitvi različnih nacionalnih predpisov in certificiranj, ki so do takrat ovirali trgovino in varnost.

Direktiva se osredotoča na tlačno opremo z največjim dovoljenim tlakom (PS) nad 0,5 bara, saj naprave s tlakom pod to mejo niso reklevarne in ne predstavljajo velika tveganja. Vključuje tudi sklope tlačne opreme, če proizvajalec želi dati ta sklop na trg kot funkcionalno celoto.

Ključne obveznosti

  • Države članice morajo sprejeti ukrepe, ki omogočajo, da se tlačna oprema in sklopi lahko na trgu pojavljajo le, če ob pravilni uporabi ne ogrožajo zdravja ali varnosti ljudi, domačih živali ali premoženja.
  • Proizvajalci morajo pred izdelavo in dajanjem na trg zagotoviti skladnost tlačne opreme z bistvenimi varnostnimi zahtevami, ki so razdeljene na splošne in posebne zahteve, odvisno od vrste opreme.
  • Uvedeni so postopki ocenjevanja skladnosti, prilagojeni različnim razredom tveganja tlakne opreme, ki vključujejo testiranje, pregled in certificiranje, navadno s sodelovanjem priglašenih organov ali inšpektoratov uporabnikov.
  • Proizvajalci morajo na tlačno opremo pritrditi oznako CE kot dokaz skladnosti s to direktivo in ostalimi relevantnimi evropskimi predpisi.
  • Države članice lahko izvajajo nadzor trga in začasno omejijo ali prepovejo dajanje na trg ali uporabo tlačne opreme, če ta predstavlja nevarnost, ob spoštovanju nadzornega postopka EU.
  • Standardi, usklajeni na evropski ravni, imajo status priporočil in pomagajo pri zagotavljanju skladnosti s tehničnimi zahtevami direktive.
  • Zagotovljena mora biti preglednost in pravica do pravnih sredstev v primeru odločitev o neizpolnjevanju zahtev.

Zadevni izdelki in subjekti

  • Direktiva obsega tlačno opremo, kot so posode, cevovodi, varnostne armature in tlačne armature, s pojmom, da ta vključuje tudi sestavne dele kot so prirobnice, šobe, spojnice, dvižne zanke ipd.
  • Vključeni so tudi sklopi, sestavljeni iz več delov tlačne opreme, ki tvorijo funkcionalno celoto.
  • Izključena je oprema, ki se že ureja z drugimi specifičnimi direktivami (npr. o enostavnih tlačnih posodah, aerosolih, vozilih, medicinski opremi, plinskih napravah itd.).
  • Prav tako so izključene posebne vrste opreme (kot so jedrska oprema, določena oprema za naftno industrijo, vozila, plastična tlačna oprema, tlak pod 0,5 bara itd.).
  • Med druge udeležence spadajo proizvajalci, pooblaščeni zastopniki, priglašeni organi, inšpektorati uporabnikov in pristojni nadzorni organi držav članic.

Časovni okvir za izvajanje

  • Direktiva 97/23/ES je bila sprejeta 29. maja 1997 in morala je biti implementirana v nacionalne zakonodaje držav članic v določenem roku (navadno v dveh letih po objavi).
  • Predpisuje se prehodno obdobje, v katerem se že obstoječa tlačna oprema, izdelana skladno z nacionalno zakonodajo pred začetkom veljavnosti direktive, lahko še daje na trg in uporablja.
  • Po triletnem obdobju od začetka veljavnosti direktive se je predvidel pregled izvajanja, ki vključuje tudi presojo, ali je treba v direktivo vključiti področje preprostih tlačnih posod (urejenih z direktivo 87/404/EGS).
  • Komisarji in organi EU še naprej spremljajo potrebo po dopolnitvah ali spremembah direktive, zlasti v zvezi s tveganji, ki jih lahko obravnavajo druge direktive ali mednarodne konvencije.

Povzetek: Direktiva 97/23/ES določa pravni okvir za tlačno opremo z največjim dovoljenim tlakom nad 0,5 bara, z namenom uskladiti varnostne zahteve in postopke ocenjevanja skladnosti na ravni EU, ter tako omogočiti prosti pretok opreme in povečati varnost uporabnikov. Vključuje širok spekter opreme in nalaga oznako CE kot potrdilo o skladnosti. Izključuje opremo, urejeno z drugimi specifičnimi direktivami ali ki predstavlja majhna tveganja. Države članice morajo vzpostaviti inšpekcijsko ter nadzorno infrastrukturo za izvajanje zahtev direktive.

Direktiva 97/23/ES se uporablja za načrtovanje, izdelavo in oceno skladnosti tlačne opreme in sklopov, katerih največji dovoljeni tlak (PS) presega 0,5 bara. Tlačna oprema vključuje posode, cevovode, varnostne armature in tlačne armature, kot tudi sklope, sestavljene iz več kosov tlačne opreme, ki tvorijo povezano in funkcionalno celoto. Direktiva izključuje določene vrste opreme, kot so cevovodi za prenos tekočin v distribucijskih omrežjih, omrežja za oskrbo in odvajanje vode, oprema, ki jo zajemajo druge posebne direktive, oprema za vozila, jedrska oprema, oprema za nadzor vrtin v naftni in plinski industriji, oprema, kjer tlak ni pomemben dejavnik pri načrtovanju (npr. motorji, turbine), plavži, visokotlačna električna oprema, ladje, zrakoplovi, določena oprema iz prožne obloge, izpušni in dovodni glušniki ter drugi specifični izdelki po seznamu v direktivi.

Butt-welding pipe fittings - Part 4: Wrought austenitic and austenitic-ferritic (duplex) stainless steels with specific inspection requirements
EN 10253-4:2025

This document specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel in two test-categories which are intended for pressure purposes at room temperature, at low temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases.
It specifies:
a)   type of fittings;
1)   type A: butt-welding fittings with reduced pressure factor;
2)   type B: butt-welding fittings for use at full service pressure;
b)   steel grades and their chemical compositions;
c)   mechanical properties;
d)   dimensions and tolerances;
e)   requirements for inspection and testing;
f)   inspection documents;
g)   marking;
h)   protection and packaging.
NOTE   The selection of the appropriate fitting (material, thickness) is the ultimate responsibility of the manufacturer of the pressure equipment (see European Legislation for Pressure Equipment). In the case of a harmonized supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently, it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.

Gas Infrastructure - Gas installation pipework with an operating pressure greater than 0,5 bar for industrial installations and greater than 5 bar for industrial and non-industrial installations - Part 1: Detailed functional requirements for design, materials, construction, inspection and testing
EN 15001-1:2023

This European Standard specifies detailed functional requirements for the design, selection of materials, construction, inspection and testing of:
-   industrial gas installation pipework and assemblies with an operating pressure greater than 0,5 bar; and
-   non-industrial gas installation pipework (residential and commercial) with an operating pressure greater than 5 bar in buildings;
starting from the outlet of the network operator’s point of delivery up to the inlet connection to the gas appliance; normally the inlet isolation valve. This standard also covers the pipework to the inlet connection of a gas appliance that is not included within the scope of the appliance standard.
NOTE 1   The use of the term installation and pipework is interchangeable.
Apart from the exceptions stated below, this standard applies to gas installations operating at ambient temperatures between −20 °C and 40 °C and operating pressures up to and including 60 bar. For operating conditions outside these limitations, reference should additionally be made to EN 13480 (all parts) for metallic pipework.
For industrial gas installations up to and including 0,5 bar and for non-industrial (residential and commercial) gas installations up to and including 5 bar in buildings, EN 1775 applies.
For gas installations that do not fall within the scope of EN 1775 or other European Standards, this standard applies.
In this European Standard, the term “gas“ refers to combustible gases, which are gaseous at 15 °C and 1 013 mbar absolute atmospheric pressure (normal conditions). These gases are commonly referred to as manufactured gas, natural gas or Liquefied Petroleum Gas (LPG). They are also referred to as first, second or third family gases as classified in EN 437:2003+A1:2009, Table 1. The given values are considered as normal conditions for all volumes given in this standard.
This European Standard is applicable to installation pipework for the carriage of:
-   processed, non-toxic and non-corrosive natural gas according to EN 437:2003+A1:2009 and EN 16726 "Gas infrastructure - Quality of gas - Group H";
-   vaporized LPG;
-   biomethane, complying with EN 16723 1;
-   vaporized LNG.
NOTE 2   The specification of vaporized LNG is equal to that of natural gas as classified in EN 437:2003+A1:2009.
This European Standard does not cover pipework for hydrogen rich gases that fall outside the definitions within EN 437:2003+A1:2009.
LPG storage vessels (including all ancillaries fitted directly to storage vessels) are excluded. Also excluded are LPG installations and sections of LPG installations operating at vapour pressure in the liquid state (e.g. between the storage vessel and any pressure regulator).
In this standard, all pressures are gauge pressures unless otherwise stated.
This standard has been harmonized to address the essential safety requirements of the Pressure Equipment Directive (PED, 2014/68/EU [formerly 97/23/EC]) relevant for the joining of gas installation pipework (assemblies) falling within the scope of the PED. These are listed in Annex ZA. However, "this Directive does not cover the assembly of pressure equipment on the site and under the responsibility of the user, as in the case of industrial installations" (PED, Preamble, 7th recital, last paragraph).
Although in this respect, the standard takes into account the essential safety requirements of the PED, no inference can be drawn from this as to whether or not the installation or parts of the installation falls within the scope of the PED. Reference should therefore be made to the PED and relevant national legislation.
This European Standard specifies common basic principles for gas supply systems. Users of this European Standard should be aware (...)

Frequently Asked Questions

An EU Directive is a legislative act of the European Union that sets out goals that all EU member states must achieve. However, it is up to each member state to devise their own laws on how to reach these goals through national transposition. Directives are used to harmonize laws across the EU, particularly for the functioning of the single market.

Directive 97/23/EC covers "Pressure equipment". There are 2864 standards associated with this directive.

Harmonized standards under 97/23/EC are European standards (ENs) developed by CEN, CENELEC, or ETSI in response to a mandate from the European Commission. When these standards are cited in the Official Journal of the European Union, products manufactured in conformity with them benefit from a presumption of conformity with the essential requirements of 97/23/EC, facilitating CE marking and free movement within the European Economic Area.
