- air handling units according to EN 1886.
This document is a parallel standard to EN 12237, EN 1507 and EN 1751, based on the same leakage classification.
Lüftung von Gebäuden - Luftleitungen und Luftleitungsbauteile, Klassifizierung entsprechend der Luftdichtheit und Prüfung
Diese Europäische Norm gilt für technische Luftleitungsprodukte für den Einbau in Luftleitungen nach
EN 1505 und EN 1506, die in den im Aufgabenbereich von CEN/TC 156 definierten Klima- und
Lüftungsanlagen zum Einsatz kommen. Dieses Dokument legt die Dichtheitsanforderungen an technische
Luftleitungsprodukte fest, d. h. an Bauteile von Luftleitungssystemen, die mehr Funktionen als den Transport
von Luft erfüllen.
Die folgenden Produkte fallen nicht in den Anwendungsbereich dieses Dokuments:
⎯ Luftleitungsbauteile wie Bögen, Reduzierstücke, Luftleitungen und T-Stücke. Für derartige Bauteile gelten
EN 12237 und EN 1507;
⎯ Flexible Luftleitungen nach EN 13180;
⎯ Luftleitungen aus Dämmplatten nach EN 13403;
⎯ Drosselklappen nach EN 1751;
⎯ Luftbehandlungsgeräte nach EN 1886.
Dieses Dokument stellt eine parallele Norm zu EN 12237, EN 1507 und EN 1751 dar, die auf der gleichen
Luftdichtheitsklassifizierung beruht.

conditionnement d’air définis dans le domaine de travail du CEN/TC 156. Le présent document spécifie les
prescriptions en matière d’étanchéité pour les composants techniques des réseaux de conduits, c’est-à-dire
les composants de ces réseaux qui n’ont pas pour seule fonction de véhiculer l’air, tels que les atténuateurs
de bruit, les caissons filtrants et les ventilateurs de conduits, etc.
Les produits suivants ne relèvent pas du domaine d’application du présent document :
- composants de réseaux de conduits tels que coudes, réducteurs, conduits et raccords en T. L’EN 12237
et l’EN 1507 s’appliquent ;
- conduits flexibles conformes à l’EN 13180 ;
- conduits en panneaux isolants conformes à l’EN 13403 ;
- registres conformes à l’EN 1751 ;
- caissons de traitement d’air conformes à l’EN 1886.
Le présent document est une norme parallèle aux EN 12237, EN 1507 et EN 1751, basé sur la même
classification de l’étanchéité.
Prezračevanje stavb - Kanali in elementi kanalov, klasifikacija tesnosti in preskušanje
Ta evropski standard velja za tehnične elemente kanalov, namenjene za inštalacijo v kanalih, ki so v skladu z EN 1505 in EN 1506, uporabljenih v klimatskih in prezračevalnih sistemih, določenih v okviru CEN/TC 156. Ta dokument določa zahteve po uhajanju za proizvode tehničnih kanalov, na primer elemente v kanalih, ki imajo več funkcij od prenašanja zraka, kot so zvočni atenuatorji, filtrirne škatle, zračni tuneli itd. Naslednji proizvodi niso zajeti v tem dokumentu: elementi kanalov, kot so kolena, zmanjševalniki, kanali in T-kosi. EN 12237 in EN 1507 veljata; fleksibilni kanali, ki so v skladu z EN 13180; kanali, narejeni iz izolacijskih kanalnih plošč, ki so v skladu z EN 13403; dušilniki, ki so v skladu z EN 1751; prezračevalne enote, ki so v skladu z EN 1886. Ta dokument je vzporeden standard EN 12237, EN 1507 in EN 1751 ter temelji na enaki specifikaciji uhajanja.

Overview
EN 15727:2010 - "Ventilation for buildings - Ducts and ductwork components, leakage classification and testing" (CEN) specifies how to classify and test leakage of technical ductwork products used in HVAC systems. It applies to components installed in sheet metal ductwork (per EN 1505 and EN 1506) that perform additional functions beyond conveying air (for example, sound attenuators, filter boxes, duct fans). The standard defines airtightness classes, measurement methods and reporting requirements used by manufacturers, test laboratories and specifiers.
Key Topics and Requirements
- Scope and exclusions: covers technical ductwork products but excludes common fittings (bends, reducers, T‑pieces), flexible ducts (EN 13180), insulation ductboards (EN 13403), dampers (EN 1751) and AHUs (EN 1886).
- Airtightness classification (A–D): classes are defined with static pressure limits and an air leakage limit (fmax) that depends on test pressure; fmax is expressed per unit surface area and varies with ptest (ptest^0.65 relationship is used in the standard).
- Measured quantities and symbols: total joint length (L), product surface area (Ap), virtual product surface area (Ac) (Ac = max(Ap, L × 0.5)), measured leakage (qvlmeasured) and tightness factor (fc = qvl / Ac).
- Test method essentials:
- Use a sealed test rig with end caps; subject sample to at least five positive and five negative test pressures up to the static pressure limits.
- Record steady leakage when pressure is stable (±5% for 5 minutes).
- Correct measured leakage for ambient temperature and barometric pressure to standard conditions (+20 °C, 101 325 Pa).
- Instrumentation and calibration: flow meters and manometers must meet accuracy requirements; periodic calibration is mandatory.
- Test report must include product design, joint length and area calculations, test pressures, corrected leakage values and achieved airtightness class.
Applications and Users
- HVAC product manufacturers and R&D teams - for product design, quality control and CE marking evidence.
- Independent testing laboratories - to perform standardized leakage testing and issue reports.
- Specifiers, consulting engineers and contractors - to select components that meet project airtightness requirements and ensure system performance.
- Tendering and procurement - use airtightness classes to compare products objectively.
