European foreword
This document (prEN 17192:2024) has been prepared by Technical Committee CEN/TC 156 “Ventilation
of buildings”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 17192:2019.
EN 17192:202Y includes the following significant technical changes with respect to 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 standard EN ISO 11925-2
— The thermal resistance test have been taken away because the test was based on flat material and is
difficult to perform on material taken from a duct. The result from Thermal resistance test is relevant
to non metallic ducts and can be added at a later stage if there is a adapted method available.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association,and supports essential requirements of
EU Directive(s) / Regulation(s).

Introduction
This document handles technical requirements and test methods for Non metallic ducts and have been
developed after the Metallic duct, the Flexible duct and the ductwork made from insulation duct board
standards. All features in the other standards have been considered, used, ignored or adapted.

1 Scope
This document defines the test methods and performance characteristics for rigid or semi-rigid non-
metallic ductwork which are used for ventilation and air conditioning of buildings.
This document does not include flexible ducts such as those made of textiles, non-metallic spiral
ductwork or others, which are handled in EN 13180 or ductwork made from insulation duct board, which
is handled in EN 13403. Requirements for the air tightness of the ventilation system for non-residential
buildings are given in EN 16798-3. For residential buildings, it is essential to apply national rules.
This document specifies methods to test rigid or semi-rigid non-metallic ductwork under laboratory
conditions. On-site tests are excluded. The test methods and performance characteristics are valid for
ventilation ducts with circular, rectangular or other cross sections.
