European foreword
This document (EN 17192:2026) has been prepared by Technical Committee CEN/TC 156 “Ventilation
of buildings”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by August 2026, and conflicting national standards shall be
withdrawn at the latest by August 2026.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 17192:2019.
— Reaction to fire tests have been updated with classifications D and E, the tests are in accordance with
the single-flame source test, according to EN ISO 11925-2.
— The thermal resistance test has been removed because it is not possible to perform this test on other
than flat materials. A thermal resistance test for non-metallic ducts can be added if a suitable method
is developed.
— Overarching requirements for the air tightness classes of the ventilation system for non-residential
buildings are given in EN 16798-3.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
Introduction
This document specifies the requirements and test methods for non-metallic ductwork and has been
developed after the standards for metallic ductwork, flexible ducts and ductwork made from insulation
duct board.
1 Scope
This document specifies the requirements and test methods for rigid or semi-rigid non-metallic ductwork
which are used for ventilation and air conditioning in buildings and excludes flexible ducts and ductwork
made from insulation duct board.
The specified test methods are under laboratory conditions and exclude on-site tests.

NOTE The default value is ATC 7 if no leakage is measured.
The operating pressure range of the ductwork is defined by negative and positive pressures.
The air tightness class shall be declared together with the operating pressure range. The declared air
tightness class shall be valid for the specified operating pressure range.
The operating pressure range shall be declared in increments of 10 Pa together with the air tightness
class.
EXAMPLE
Example declaration:
Operating pressure range Air tightness class declared
−20 Pa to +50 Pa ATC 2
−60 Pa to +260 Pa ATC 4
−40 Pa to +110 Pa ATC 3
Example explanation:
At an operating pressure of 40 Pa, air tightness class is ATC 2.
At an operating pressure of 125 Pa, air tightness class is ATC 4.
At an operating pressure of 90 Pa, air tightness class is ATC 3.
5.3 Pressure loss
The pressure loss shall be declared for every duct and component of the ductwork.
5.4 Operating temperature
The temperature class defines the range of the operating temperature for the use of the ventilation
ductwork. The designation for the lowest operating temperature is STL and for the highest operating
temperature STH.
The designation is followed by the operating temperature.
