1 Scope
This European Standard:
— specifies requirements and gives reference to the test methods defined for fire resisting duct
sections and their associated components (e.g. hangers and other items as fire stopping seals
proven at the time of testing), which are intended to be installed in heating, ventilation and air
conditioning (HVAC) systems in buildings, and
— specifies a method for the verification of constancy of performance of these products to the
requirements of this document, and
— specifies the marking and information on installation and maintenance of these products.
This document:
— is applicable to fire resisting duct sections placed on the market used in fire resisting air
distribution duct systems excluding smoke extraction systems, and
— governs associated components used together with duct sections (e.g. turning vanes, silencers,
access panels, with the exceptions of, e.g. fire dampers which are covered by separate standards).
To avoid duplication, reference is made to a variety of other standards. To this end, it is advised to read
this document in conjunction with EN 13501-3 for classification and EN 1366-1 and EN 15882-1 for
details of the fire resistance testing and the direct and extended field of application.
This document does not consider in detail the detrimental and/or corrosive effects that can be caused
by chemical processes present in the atmosphere, which are drawn through the system intentionally or
inadvertently.

The compliance of a fire resisting duct section with the requirements of this standard and with the
performances declared by the manufacturer in the DoP shall be demonstrated by:
— determination of the product type;
— factory production control by the manufacturer, including product assessment.
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
Annex D gives an example of declaration of Performance (DoP).
6.2 Type Testing
6.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless this standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, classified without further
testing (CWFT) and conventionally accepted performance).

---------------------- Page: 10 ----------------------
oSIST prEN 15871:2017
prEN 15871:2017 (E)
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same
AVCP system on the same product or products of similar design, construction and functionality, such
that the results are applicable to the product in question.
NOTE Same AVCP system means testing by an independent third party, under the responsibility of a notified
product certification body.
For the purposes of assessment, the manufacturer’s products may be grouped into families, where it is
considered that the results for one more characteristics from any one product within the family are
representative for those same characteristics for all products within that same family.
Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in
the standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified fire resisting duct section (unless a member
of the same family), or
— at the beginning of a new or modified method of production (where this may affect the stated
properties), or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the fire
resisting duct section design, in the raw material or in the supplier of the components, or in the method
of production (subject to the definition of a family), which would affect significantly one or more of the
characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics
need not be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European
specifications may be presumed to have the performances declared in the DoP, although this does not
replace the responsibility on the fire resisting duct section manufacturer to ensure that the fire resisting
duct section as a whole is correctly manufactured and its component products have the declared
performance values.
6.2.2 Test samples, testing and compliance criteria
The number of test samples of fire resisting duct sections to be tested/assessed shall be in accordance
with Table 1.

6.2.3 Test report
The results of the determination of the product type shall be documented in test reports. All test reports
shall be retained by the manufacturer for at least 10 years after the last date of production of the fire
resisting duct section to which they relate.
6.2.4 Shared other party results
A manufacturer may use the results of the product type determination obtained by someone else (e.g.
by another manufacturer, as a common service to manufacturers, or by a product developer), to justify
his own declaration of performance regarding a product that is manufactured according to the same
design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same
kind, provided that:
— the results are known to be valid for products with the same essential characteristics relevant for
the product performance;
— in addition to any information essential for confirming that the product has such same
performances related to specific essential characteristics, the other party who has carried out the
1)
determination of the product type concerned or has had it carried out, has expressly accepted to
transmit to the manufacturer the results and the test report to be used for the latter’s product type
determination, as well as information regarding production facilities and the production control
process that can be taken into account for FPC;
— the manufacturer using other party results accepts to remain responsible for the product having
the declared performances and he also:
— ensures that the product has the same characteristics relevant for performance as the one that
has been subjected to the determination of the product type, and that there are no significant
differences with regard to production facilities and the production control process compared
to that used for the product that was subjected to the determination of the product type, and
— keeps available a copy of the determination of the product type report that also contains the
information needed for verifying that the product is manufactured according to the same
design and with raw materials, constituents and manufacturing methods of the same kind.
6.2.5 Cascading determination of the product type results
For some construction products, there are companies (often called “system houses”) which supply or
2)
ensure the supply of, on the basis of an agreement, some or all of the components (e.g. in case of
3)
windows: profiles, gaskets, weather strips) to an assembler who then manufactures the finished
product (referred to below as the “assembler”) in his factory.
Provided that the activities for which such a system house is legally established include
manufacturing/assembling of products as the assembled one, the system house may take the
responsibility for the determination of the product type regarding one or several essential
1)
The formulation of such an agreement can be done by license, contract, or any other type of written consent.
2)
This can be, for instance, a contract, license or whatever kind of written agreement, which should also contain
clear provisions with regard to responsibility and liability of the component producer (system house, on the one
hand, and the assembler of the finished product, on the other hand).
3)
These companies may produce components but they are not required to do so.
10
---------------------- Page: 12 ----------------------
oSIST prEN 15871:2017
prEN 15871:2017 (E)
characteristics of an end product which is subsequently manufactured and/or assembled by other firms
in their own factory.
When doing so, the system house shall submit an “assembled product” using components manufactured
by it or by others, to the determination of the product type and then make the determination of the
product type report available to the assemblers, i.e. the actual manufacturer of the product placed on
the market.
To take into account such a situation, the concept of cascading determination of the product type might
be taken into consideration in the technical specification, provided that this concerns characteristics for
which either a notified product certification body or a notified test laboratory intervene, as presented
below.
The determination of the product type report that the system house has obtained with regard to tests
carried out by a notified body, and which is supplied to the assemblers, may be used for the regulatory
marking purposes without the assembler having to involve again a notified body to undertake the
determination of the product type of the essential characteristic(s) that were already tested, provided
that:
— the assembler manufactures a product which uses the same combination of components
(components with the same characteristics), and in the same way, as that for which the system
house has obtained the determination of the product type report. If this report is based on a
combination of components not representing the final product as to be placed on the market,
and/or is not assembled in accordance with the system house’s instruction for assembling the
components, the assembler needs to submit his finished product to the determination of the
product type;
— the system house has notified to the manufacturer the instructions for manufacturing/assembling
the product and installation guidance;
— the assembler (manufacturer) assumes the responsibility for the correct assembly of the product in
accordance with the instructions for manufacturing/assembling the product and installation
guidance notified to him by the system house;
— the instructions for manufacturing/assembling the product and installation guidance notified to the
assembler (manufacturer) by the system house are an integral part of the assembler’s Factory
Production Control system and are referred to in the determination of the product type report;
— the assembler is able to provide documented evidence that the combination of components he is
using, and his way of manufacturing, correspond to the one for which the system house has
obtained the determination of the product type report (he needs to keep a copy of the system
house’s determination of the product type report);
— regardless the possibility of referring, on the basis of the agreement signed with the system house,
to the latter’s responsibility and liability under private law, the assembler remains responsible for
the product being in compliance with the declared performances, including both the design and
...
